Hoji diseases can provoke pests, bacteria, fungi, viruses and external factors. Damage and various cancers can occur not only due to pests, but also as a result of keeping them in inappropriate conditions. High humidity and warm temperatures contribute to the spread of fungal diseases, at the same time insect pests perfectly spread in dry and hot conditions of the plant.

Diseases to which hoyas can be affected:
1. Bacterial diseases.
This type of disease is caused by pathogenic bacteria that cause the disease. Bacteria that penetrate plant damage can spread throughout the vascular system.
The main symptoms of bacterial damage are: the stem and branches of the plant dry out and ulcers form, reddish spots may appear on the leaves, leaves turn black-brown with a yellowish halo, and watery spots may appear on the leaves and leaf stalks. When the central zone of the damaged part softens, a sticky, foul-smelling liquid is released from it.
In order to avoid infection with a bacterial disease, you should first of all try not to leave cuts on the plant; after pruning, disinfect with copper preparations.
Methods of control: treatment with preparations containing copper.
2. Viral diseases.
These are pathologies caused by viruses: non-cellular organisms that are able to penetrate certain living cells and reproduce only within these cells.
The main symptoms of plant damage by viral disease: on the leaves may appear spots of light yellow or pale green color of various shapes, between the veins or on the veins themselves, on which the thickening occurs.
Methods of control: a plant affected by a viral disease is very difficult to treat. Such a plant must be isolated from other plants in order to avoid contamination of other healthy plants. Disease vectors are pests.
3. Fungal diseases.
Fungal diseases are caused by defeat phytopathogenic imperfect mushrooms.
Main symptoms: root rot - the plant stops growing, leaves turn yellow and wither, gray-brown roots that soften. It can also appear as powdery mildew: the appearance of pale-gray spots on the leaves, which increase with time. When the form of the disease is neglected, such spots can appear both on the stems and on the flowers. Gray decay manifests itself in the form of brown spots of dead tissue and a gray velvety coating consisting of mycelium and spores. First appears on drying leaves and shoots, and then moves to healthy areas of the plant.
Methods of struggle: transplanting plants in a new pot with fresh soil. Compliance with the correct irrigation. Use drugs based on benamyl or thiram. When powdery mildew, you can use fungicides (sulfur, benlate, carbonates of copper, manganese, zinc). For treatment of gray rot spray plants with 1% Bordeaux mixture or 0.5% captan solution.
4. Noncommunicable diseases.
These are diseases that are usually caused by non-compliance with the rules of plant maintenance. As supercooling and too high temperature adversely affect the state of hoya. Increased temperature and direct sunlight can cause burns on the leaves and other parts of the plant. Owing to too cold a temperature, the lower leaves may turn yellow and new shoots develop poorly. Cracks in the trunks and branches may appear due to a sharp temperature drop.
Improper watering can lead to wilting of the plant or to the decay of the roots - in case of stagnant water in the soil. Excessive stretching of shoots is due to the lack of the required amount of light illumination. Care should also be taken with the hoya fertilizer. Incorrect use can lead to discoloration of leaves and flowers. You can not treat fertilized plants weakened plants and in the hot time of the day.
For diseases of hoi, Epin or Zircon preparations can also be used. Epin can spray hoi leaves and stalks in the case of hypothermia and waterlogging - the greatest effect is achieved after 10 days. In the case of treatment with Appin, it is undesirable to put the plant in bright light, since the light destroys the particles of epin. In case of overdrying of the plant and the defeat of fungal diseases, Zircon can be used - the effect of the action is immediate and decreases within 10 days. Zircon is more suitable for restoring the root system of a plant, Epin - the ground part - leaves and stems. Both of these drugs are used if the plant has suffered severe stress and needs help in recovery.

Hoyi pests:
1. Spider mite - arthropod insect, similar to a small spider, which lives mainly on the lower part of the leaf. As a result of damage to the spider mite, the leaves become covered with yellow dots, spots and fall. A web forms between the leaves and the stem. Favorable conditions for the emergence and reproduction of spider mites - high temperature and dry air. Therefore, in order to prevent infection with spider mites, it is recommended to spray the plant in the hot season (as often as possible - the tick is afraid of moisture).

2. Shchitovka - larvae, attaching to parts of the plant (leaves or stems), covered with a waxy coating as a shield. There are many varieties of scythos, but they all suck up the sap of the plant, the leaves first turn yellow, then they dry up - brown and as a result they fall. The plant can die if you do not carry out treatment measures to destroy the pest.

3. Redhead - these are insects of 2-5 mm in size, which have a wax cover. The emerging larvae crawl around the plant and stick to the leaves and trunks. Favorable breeding conditions - moisture and heat. The mealybug is especially dangerous - an adult insect of 3.5 mm orange or pink color, the body of which is covered with a waxy coating. Leaves that are damaged by mealybug become yellow and fall off. New shoots are slowing in growth. Soot fungi can settle on the secretions of the worms.

4. Nematodes - These are colorless worms that have a body 1.3 cm long and 0.9 cm wide. As a result of damage by a nematode, blooms appear on the roots of the plant - galls in which nematodes live and reproduce. These bloated galls can be of various sizes depending on the degree of nematode damage and the weakness of the plant. When a plant is affected by a nematode, it stops growing, leaves turn yellow and in an advanced stage can die, since damaged roots cannot fully provide the plant with essential nutrients. In addition, many nutrients are absorbed by the pests themselves. There are also stem nematodes - worms that live in the stem of a plant. As a result of damage by stem nematodes, the stems and shoots develop ugly: leaves become shriveled, whole bunches of thin shoots with small leaves appear. The stem core acquires a brown color.

5. White fly - this insect butterfly resembles with its appearance an ordinary mole. But the main harm bring the larvae that feed on the juice of the leaves. Usually adult insects are on the back of the sheet. From the defeat of the whitefly on the leaves appear small round spots, after which the leaves turn brown and fall off.

6. Poddur - White-winged insect 1-2 mm long, which can jump. Appears as a rule in a pot with a soil with strong waterlogging. Insect infects terrestrial parts of the plant.

Pest Control Techniques:
1. mite:
Drug sunmite - effective in combating a number of types of mites: spider mite, strawberry mite, grape mite.
Drug benefits:
allows you to fight ticks on all phases of pest development (egg - larva - nymph - adult tick),
use of the drug does not cause cross-resistance,
the drug begins to affect the pest within 15 minutes after treatment,
the drug is characterized by a prolonged period of action (5-6 weeks),
the effectiveness of the drug is not affected by temperature fluctuations
safe for crops and low toxic to warm-blooded animals,
A side effect of Sunmite is the effect on the whitefly.
Mechanism of action:
Sunmite is a contact acaricide, characterized by high activity in pest control at all stages of their development (egg - larva - nymph - adult tick).
Sunmite has a contact effect, therefore, to achieve the maximum effect, it is of fundamental importance to uniformly apply it to the surface of plants during spraying,
It is recommended to use Sunmite after flowering, when the population of ticks reaches or exceeds the threshold level,
In order to avoid accelerating the development of resistance, Sunmite should be used no more than once a year,
Application: 0.5-0.75 g per 1l of water.

Drug apollo - contact acaricide of specific action for the fight against eggs and young larvae of red fruit mites Panonychus spp. and common spider mites Tetranychus spp.
The drug perfectly controls the mite MacDaniel, the spider carmine-red mite, the common spider mite, the Pacific mite, the citrus red mite, the red apple tick, the Schlechtendal mite.
Application: 0.2-0.6 ml per 1 l of water, with strong infection, repeat treatment after 3 weeks. Or combine with another drug.
A feature of this drug is that it kills the larvae and eggs, and mites sterilize.
In order to avoid the occurrence of resistance in spider mites, they do not recommend using Apollo more often 1 time per season. In extreme cases, 2 times. Therefore, the second treatment, if necessary, it is better to hold a different drug.

2. Shchitovka, thrips, whitefly, aphid:
Drug Aktara (water-dispersed granules) - to protect against aphids, whiteflies, thrips, scutes, shields, pouras.
The drug can be applied by irrigating the soil under the plants.
When watering, the rate of consumption of the drug is 1 g / 10 l of water, with a plant height of up to 40 cm. The consumption rate of the working fluid is 10 l per 250 pots. Do not over-wet the soil.
In some cases, 4 g of aktar should be dissolved in 10 l of water and shed evenly. It is also permissible to dissolve 4 g of aktar in 2 liters of water. That is, 1.4 g of the package is dissolved in 0.7 l of water (this is the maximum permissible concentration specified by the manufacturer).
Adding Aktara in the soil allows you to completely abandon the spraying.
The period of protective action: 14–28 days when spraying the crop, when applying soil - 40–60 days.
Influence speed: insects stop eating 30 minutes after treatment with the preparation, complete death of insects occurs after 24 hours. When watering the exposure time comes later.

Drug Aktofit - a biological product to combat aphids, mites, whitefly, thrips, etc.
It is safe for humans, soil arthropods and earthworms, does not adversely affect the biological activity of the soil, is not phytotoxic.
Recommendations for use:
vegetable mites 4ml / l, 1-2 treatments
thrips miner mol 10-12ml / l, 1-2 treatments
spider mite 2-3ml / l, 1-2 treatments
Aphi 6-8ml / l, 1-2 treatments.

3. Redhead:
It is recommended to remove them manually with a brush or cotton swab moistened with alcohol. Plants are treated with special insecticides — spray on the affected parts preparations based on white oils (10-20 g per bucket of water).
You can use a mixture of such drugs: 1g. Aktara, 1g. Mospilan, 1g. Confidor Maxi. Each preparation is diluted separately in 330 ml of water, and then the leaves are mixed and processed; it is possible to water the soil in which the damaged plant grows. After that, you can re-process the drug Aktara 1g. 250 ml of water with an interval of 5 days.
Folk means of dealing with the b heart:
1) the leaves and stems can be washed once every 7 days with soapy water, onion juice or garlic with soap,
2) wash with an infusion of orange or mandarin peels infused for 1-2 days,
3) plan 1 tsp simple soap, dissolve in hot water. Then add to 1 liter, add 1 tbsp. spoon of alcohol or 2 tbsp. spoons of vodka. Sprinkle the plant with the solution, after covering the ground in a pot. The next day, rinse the plant with warm water. The treatment must be repeated after 3-4 days,
4) 25-70 g of garlic knead, pour 1 liter of boiling water, insist 6 hours, strain and spray the plant,
5) with a brush dipped in calendula infusion, it is easy to remove the lump with the pest and thoroughly lubricate this place. This is done in the evening. Within two days, the plant should be protected from the sun.


5. Nematode:
1) in order to avoid the appearance of nematodes, it is recommended to add marigold leaves or walnut shells to the ground. It is also known that the infusion of garlic can interfere with the reproduction of nematodes,
2) first you need to change the soil to fresh, and the pots are well steamed,
3) effective specific drugs - nematocides (chloropicrin, methyl bromide),

6. Podura: first of all, the soil should be dried, and then sprinkled with lime, tobacco dust or hexachlorane.

Why the flower does not grow?

Common mistakes when growing hoi:

  • Incorrect pot size.
  • The amount of incoming light. Hoya loves bright lighting. But you should not overdo it, as in strong sunlight burns on its leaves.
  • Watering should be done rarely, only after the land is completely dry.
  • The soil. Suitable for growing fleshy, loose soil.

We also talked about why hoya does not bloom and what to do about it. Read about it in another article.

What are the problems and what to do to solve them?

Common problems of improper care - slowing or stopping growth, changing the color of the leaves. There is also spotting on the leaves, they curl and dry. Other symptoms depend on the specific disease.

Yellowing around the edges is a symptom of improper watering or watering with hard tap water, prolonged drying of the soil.

Yellow spots are also a sign that hoya has been burned by direct sunlight.

  1. Finding out the exact cause and normalization of care.
  2. Spraying with copper-containing or chemical preparations for prophylaxis (weak solution of Epin, Fitoverma).
  • Excess moisture.
  • Choosing the wrong place.
  • Dry and hot air.
  1. Put the plant in a warmer place.
  2. Watering exercise soft water at room temperature.
  3. Feed the soil with a balanced fertilizer (Gumi-20 wagon or equivalent).

  • poor lighting
  • wrong pot size,
  • warm wintering
  • pruning of peduncles,
  • lack of water or food.

  1. Adjustment of conditions of detention.
  2. Treatment with copper preparations.

Infection occurs when:

  • immoderate watering
  • high air humidity
  • poor water quality
  • moisture stagnation
  • watering in the cold.

  1. Transplant plants in a new and clean pot.
  2. Adding updated soil.
  3. Compliance with the frequency of watering.
  4. Treatment with special preparations (Fundazol, Topaz).

Illness appears with poor ventilation and high humidity, if the plant is cramped or in a packed soil soil.

  1. Disinfection of instruments and soil.
  2. Regular airing of the room, greenhouses.
  3. Improved lighting for the plant.
  4. Extreme measures - processing chemicals. This is 1% Bordeaux mixture or 0.5% Kaptan solution.

  • wet air,
  • excess nitrogen
  • temperature drops.

  1. Remove affected parts.
  2. The use of special preparations (Topaz, Thiovit) and fungicides.
  3. Soil saturation with manganese, zinc, sulfur.

White fly

This is an insect that resembles a mole in appearance. The main harm to the plant is caused not by adults, but by the larvae, since the basis of their nutrition is the sap of the leaves.

Eliminate whitefly complex.

Whitefly fighting methods:

  1. Manual pest collection. Wipe the plate plate with a cotton pad or toothbrush, pre-moisten them in soapy water.
  2. Folk recipes.

  • Dust the soil in a pot with ashes, sprinkle garlic with garlic solution (100 g per 1 l of water, leave for 5 days, dilute with water before processing).
  • Another folk remedy is dandelion infusion: take 50 g of roots and dried leaves, pour 3-4 liters of water, leave for 5 hours. Strain before spraying.
  • Insecticides. These are Konfidor, Aktellik, Aktar. The dosage is indicated on the package, choose the volume for spraying ornamental plants.
  • Insect whose body is covered with a waxy coating. The average size of individuals - 2-5 mm. The larvae flood the whole plant, stick to the leaves and the stalk. The reason for the appearance of pests is heat and high humidity.

    Measures to combat the b heart:

    • Manual cleaning. To do this, you will need to moisten the cotton wool in alcohol and wipe the plant where the worm appeared.
    • Folk recipes. This soapy water, diluted juice of onions or garlic, infusion of citrus peels. The remedies have a pungent odor that scares the worm.
    • Also use special chemicals: Aktrata, Konfidor-maxi, Mospilan.

    Red spider mite

    Appears in rooms with poorly humidified air. Живет на обратной стороне листьев, листовая пластина покрывается желтыми пятнами. Главный признак – паутина.

    Методы борьбы с вредителем:

  • To free hoyu from spider mites, first you need to rinse its leaves with warm soapy water.
  • Remove single parts of the plant affected by the pest.
  • Water and cover the plant with cellophane, leave for 3 days.
  • Effective chemicals from ticks - drugs Neoron, Apollo and Sunmite.
  • These are transparent worms, the average length of which is 1 cm. When infected, blooms of various sizes appear on the roots - nematodes live and multiply inside these swellings. With mass infection, the root resembles a bunch of grapes.

    The reason for the emergence of root nematodes is watering: the pest is transmitted to a new plant from an infected one through water.

    How to eliminate pests:

    1. The only effective method is re-rooting.
    2. Chemical agent for the fight - Ekogel. The minus of the substance is that it does not kill the parasite, but only slows down its reproduction. During this time, the plant can root and grow strong.
    3. Preventing the appearance of these worms - changing and disinfecting the soil, steaming pots. Also, for the prevention, you can add to the soil the shell of nuts or marigold leaves.

    Another name - springtails. In fact, these insects do not belong to pests, they are relatively safe for plants. But leaving them on hoy do not need. When a large population of podura cause significant damage.

    In the soil there is usually a small amount of undercuts that are invisible to the human eye and do not cause harm to the plant. An increase in the population occurs for such reasons: the stagnation of water and the formation of silt on the surface, parts of the hoya began to rot.

    How to remove:

    1. At the first signs you need to dry the soil, then sprinkle it with tobacco dust or lime.
    2. Chemicals from pest. Basudin, Pochin (sprinkle the granules on the surface with a thin layer), Mospilan, Aktara.

    These are small insects of different colors (there are orange, gray, black). The cause of occurrence is infected neighboring plants or contaminated soil. Also, winged females can fly into the room through the open window.

    Remedies:

    • The pest does not tolerate the smell of geranium. This is the easiest way to get rid of insects.
    • If there are no geraniums on hand, wash the leaves with soapy water.
    • Recipe for spraying. Chopped onion, garlic, fresh leaves of tomatoes pour 1 liter of boiling water, leave for 6-8 hours, drain, sprinkle. Alternative - tobacco solution (fresh leaves pour boiling water).
    • In the list of effective chemicals - Konfidor, Fitoverm, Enzio, Aktellik.

    These are small bugs whose body color corresponds to the color of leaves (green, yellowish), so it is almost impossible to notice them. A favorable factor for the appearance is dry air.

    Getting rid of effectively:

    1. Plant isolate.
    2. To get rid of the parasite you need to wipe all parts of the hoya with water with the addition of laundry soap.
    3. From folk methods using tinctures of citrus, garlic or onion.
    4. Of the chemicals - Fitoverm, Angio, Aktara, Aktellik.

    There is a large variety of subspecies of this pest, but they all cause the same damage to the plant. The parasite sucks the juice out of hoy, after which it has a similar effect, as with lesions by other insects - the leaves turn yellow, dry up and fall off.

    The causes of the appearance of shield insects are the weakened immunity of hoya, an oversupply of nitrogen in the soil, dry air, improper watering, and insufficient light.

    How to remove the parasite:

    1. To get rid of shitovki need to remove them manually from the leaves.
    2. After rinse with water and medical extract of onion and garlic.

    Of the chemicals suitable Aktara and Actofit.

    Below you can see how the Hoya looks like with various problems and ailments.
    Falling and yellowing leaves:

    Pests on the plant:

    Conclusion

    So, now you will find out why diseases appear in a flower and what to do, for example, if the leaves turn yellow.

    Hoya is ideal for growing indoors (you can find out if you can keep wax ivy at home and see photos of the plant here, and in this article you will find all the secrets of plant reproduction at home). It does not require scrupulous and constant care. For a good flowering plant is enough to land in a suitable place and follow simple rules of care: properly water, keep the light balance. remember, that any violation of conditions of detention weakens hoyi’s protectioncause disease or pest attacks.

    Root causes rot

    This disease is also caused by pathogenic fungi. It develops only at high humidity.

    His provoke:

    • systematic play of indoor plants,
    • content at low temperatures,
    • excess nitrogen in the soil.

    Excess water in earthen coma is the most common cause. It leads to decay of the roots or other parts of the plant, and then to the death of the whole flower. In places of defeat, the tissues soften, they turn into muck with an unpleasant smell.

    When root rot occurs, the situation is more insidious. At the onset of the disease, the plant behaves as if it lacks water. But additional watering only aggravates the situation. In order to save the wax ivy from rot, all affected parts must be removed by treating cutting sites with activated charcoal. If the disease settled on the roots, then only grafting will help.

    Bacterial infections and insects

    Pathogenic bacteria cause the wilting of a flower, which begins at its apex and then spreads to the whole plant. Another characteristic feature is the appearance of spots on the leaves. They quickly spread over the entire surface of the plate, causing it to yellow and fade. Measures to combat bacterial infections is the content of culture in dry air for the period of treatment and treatment with copper preparations.

    Waxy ivy affects such pests:

    1. Nematodes are colorless worms up to one centimeter in size. Most often settle on the roots, with the result that they do not provide the plant with nutrients. The hoya struck by nematodes turns yellow, sheds leaves, stops growing.
    2. Spider mite settles on the bottom of the leafy plates of wax ivy. A cobweb forms in their sinuses, and the leaves themselves become stained. The spider mite does not like water, so when it appears, it is necessary to spray a flower as often as possible.
    3. The shield is like small tubercles covered with a layer of wax. It feeds on plant sap, causing it to dry. The leaves of wax ivy first turn yellow and then turn brown. Affected flower dies over time.
    4. The buckworm can reach up to 5 mm in size. It attaches to the leaves, emits sticky drops, on which a black fungus settles with pleasure. Thus, the plant receives a "double blow", does not allow new shoots and dies.
    5. A fool is different from other pests in that it can jump. This white-winged insect develops with significant watering of the earthy coma. It affects only the ground part of the hoy.
    6. The whitefly resembles a small mole. Its larvae actively feed on plant sap, located below the leaf. Culture is covered with small spots.

    All pests cause hoya leaves to fall, stop its growth. A weakened plant quickly dies, if not to take measures to destroy insects. When nematodes of wax ivy are detected, they are necessarily transplanted into a new, disinfected land. In all cases, the treatment is carried out with one of the preparations according to the instructions: Actofit, Aktara, Konfidor-maxi, Sunmite, Appolo and others. As a rule, watering and spraying them carried out twice with a short break.

    How to save the plant from drying out

    There is no need to water hoyu often, she does not like it. At the same time the flower does not tolerate irrigation with cold water. In the summer it is watered more often, not forgetting about regular spraying. If the wax ivy began to dry, it is necessary to adjust the watering and bathing the plants. For this non-flowering specimen is immersed in water for 40 minutes. It is also worth cutting off a few cuttings and rooting them.

    Blooming wax ivy is strictly forbidden to bathe.

    Helpers for resuscitation hoy are drugs Zircon and Appin. The first restores the root system, and the second - rescues the ground part (stem and leaves). With a solution of Epina, the flower is sprayed, avoiding exposure to sunlight on hoya. If you use several means at the same time, then even a very ruined flower can be saved within 10 days.

    What if the leaves turn black?

    Many do not know why the ivy leaves turn black and how to treat them? Often pathogenic bacteria cause discoloration of the plates. They infect the plant through wounds or cuts and spread throughout its body. At the same time, branches of waxy ivy dry up and ulcers form on the trunk.

    One of the reasons that hoya does not bloom is inappropriate indoor air temperature.

    To save ivy from drying:

    • plant to isolate
    • prune affected segments
    • process copper-based drugs
    • do not spray during quarantine and keep in a dry place.

    If the above measures to save wax ivy failed, then it is destroyed. Because another cause of black foliage may be a viral disease that is practically not treatable.

    Why do the hoya leaves turn yellow?

    This flower does not like extreme conditions: heat or cold. At low temperatures in the room at the hoi leaves begin to turn yellow, it slows growth. The discoloration of the plates also occurs during sunburns.

    Yellowed leaves must be removed. They will not restore their tone any more, but may become a place for the development of pathogens of various diseases. For plants it is important to choose a room with optimal illumination or cover the window with a grid. Another reason for leaf color change can be rot, as well as insect damage.

    If the hoya leaves turn yellow and fall off, then an excess of sun can be the cause.

    The fall of hardwood plates can be triggered by various factors:

    • waterlogging earthen clod,
    • moving the plant to another place
    • cooling, especially in winter due to airing.

    If the hoya leaves turn yellow and you do not know what to do, then the first thing you should resort to is to move the pot from the cold room. Watering should be at room temperature or slightly warm. If there is not a single leaf on the plant, this is not a reason to throw it away. You can cut wax ivy at a height of about 5 cm from the ground and wait for new shoots.

    Knowing what hoyi diseases are and how to identify them, you can grow a healthy and incredible beautiful plant. Proper watering and the corresponding air temperature in the room - the key to abundant flowering.

    Non-communicable hoi diseases, how to eliminate them

    Such diseases are caused by improper maintenance of the plant and care for it. Hoya does not like too low temperature, and heat, which, together with direct sunlight can cause burns on the plant. If the temperature is too low, the leaves will turn yellow, and new shoots grow very slowly. The consequences of a sharp temperature drop can be cracks in the trunk.

    If you do not follow the rules of watering hoy, the stagnation of water in the soil can lead to rotting of the roots, as a result of which they disappear. And if the plant does not have enough lighting, the shoots will be excessively stretched. Carefully and responsibly should be taken to the hoya fertilizer. If fertilizing is used incorrectly, the leaves and flowers of the plant may become discolored. Do not fertilize hoyas in hot weather.

    Non-infectious diseases of wax ivy can be treated with Epin and Zircon. In the case of waterlogging or hypothermia, "Epinay" sprayed the leaves and stalks of hoya. The effect will be achieved 10 days after the start of use of the drug. "Epin" is afraid of sunlight, so do not put the plant under direct rays during processing. "Zircon" is used to treat hoyas when the plant is over dried. It gives an instant effect that lasts for 10 days.

    “Zircon” restore the hoya root system, and “Epinom” - the aboveground part of the plant. Both drugs are well help wax ivy recover from severe stress.

    Hoya does not bloom

    If the home hoya does not bloom, there are several reasons for this, so before you do something, you need to understand what exactly provoked the problem in your case.

    The main reasons why ivy does not bloom are as follows:

    • age of the plant
    • lighting,
    • wintering conditions
    • support,
    • top dressing
    • watering,
    • soil composition
    • pot size
    Age of the plant. Hoya, begins to bloom in the second or third year of life, but in some cases, its flowering begins earlier.

    Lighting. The best illumination for the hoi is the south or southeast window. But there are exceptions: there were cases when wax ivy bloomed on the western windows and even in dark corridors. If your hoya does not bloom, move it to where it will receive more light.

    Support. Hoya does not like to be tied to a support so that the shoots descend. First you need to grow long shoots and only then gradually bind the plant to the support. The main thing is to properly form a home hoyu. No need to remove old flower stalks.

    Watering. Wax ivy does not need frequent watering. In between water procedures, the soil should be completely dry. In the cold season, hoyu is rarely watered, in the summer it is sprayed a little more often and regularly.

    Top dressing and soil. The soil in which hoya grows must be loose and breathe well. Usually it is sand, peat and substrate mixed in equal parts. Sometimes the plant is fertilized, but not often. Some feed hoya with mullein so that it blooms well. For wax ivy, fertilizing is also suitable, which is given to succulents and cacti.

    Leaves dry, turn pale, curl

    If the leaves of wax ivy fade, dry and curl, This may be due to the low temperature in the room where hoya is located. It is also possible that This is due to the bright sun.

    Leaves fall

    If wax ivy leaves fall, there may be several reasons. For example, excessive moisture appeared in the ground, or do you moved hoya to another place. Leaf fall may occur due to severe hypothermia in winter, so do not put the plant on a cold window and do not water it with cold water.

    Bacterial diseases hoi, how to get rid of them

    This type of disease is caused by pathogenic bacteria. They penetrate the damaged areas of the plant and spread throughout the vascular system of hoya. The main symptoms of ivy damage by bacteria are dried branches and the trunk with formed ulcers, as well as reddish spots and watery spot on the leaves. Also, the leaves can become black-brown with a yellowish tinge.

    When the damaged area softens, a sticky liquid with an unpleasant odor will be released from it. To prevent bacteria infection, you need to monitor the integrity of the trunks and leaves, avoiding the appearance of cuts on them. After pruning, be sure to disinfect with copper based preparations.

    Treatment methods will be effective only when the local lesion and bacteria have not yet reached the vascular system of hoya. The diseased plant must be isolated, put in a room with dry air, not sprayed. If you notice the disease in its initial stages, you can defeat it by removing all the affected parts of the hoya and capturing some healthy tissue.

    Before each cut, treat the scissors or knife blade with an antiseptic. Then sprinkle hoy bordeaux mixture or preparations containing copper. If the processing has not brought results, the flower must be destroyed.

    Bacterial spotting

    Spots on the leaves appear on the dead spots. They do not have clearly defined edges, the structure is rather vague. The spots may be oily or glassy. They quickly spread over the entire area of ​​the leaf, which then dries, turns yellow and falls. If hoya is in a humid and warm environment, this greatly increases the rate of spread of the disease.

    They are manifested in the softening and dying off of the plant tissues, then on the affected place a rotten slush with an unpleasant odor is formed. The most common rot affects plant species with large fleshy leaves. A hotbed of rot can occur on any part of ivy: flowers, leaves, roots. The reason for the occurrence usually lies in violations of conditions of detention, such as high humidity of the soil, cold room, an excess of nitrogen fertilizers.

    Hoi mushroom diseases, their treatment methods

    Such diseases are caused by the defeat of the plant by imperfect phytopathogenic fungi. Characteristic symptoms: the flower stops growing, the leaves wither and turn yellow, the roots become brown and soft. In some cases, the leaves appear powdery mildew in the form of gray spots, which over time significantly increase in size. When the disease is started, the spots appear on the flowers and stems. Gray rot consists of spores and mycelium. First of all, it appears on the drying shoots and leaves, and later affects the healthy parts of the hoya.

    To overcome the disease, you need to transplant the flower in fresh soil and strictly follow the rules of watering. We recommend using preparations based on thiram and benamyl. Чтобы раз и навсегда избавиться от мучнистой росы, необходимо также использовать фунгициды: бенлат, карбонат меди, серу, цинк, марганец. Отличным средством в борьбе с серой гнилью является бордоская смесь. Опрыскивайте ей хойю однопроцентным раствором.

    Чаще всего эти грибы поражают слабые растения: who have mechanical damage and undergoing stress. All above-ground parts of the hoya come under attack, but the focus of the disease always begins with the leaves. The spots on them look completely different. It depends on the type of fungus that caused the disease.

    When the source of infection is Kabatiellazeae, small yellow specks appear. If you look at them through a magnifying glass, inside you can see a black or brown dot. As the disease progresses, the stain increases, instead of a dot, a bezel appears with a gray spot inside.

    If hoyu was struck by the Colletotrichumorbiculare mushroom, then you will see brown spots on the leaves with a yellow border. When the disease progresses, the spots merge, then the affected areas dry out, and holes are formed in the leaves.

    Colletotrichumtrichellum mushroom leaves large brown spots with a yellow or gray tint and gray spores.

    Anthracnose usually affects the plant in warm and humid weather, as the mushrooms feel good at 90% air humidity and 22-27 ° C. The disease is provoked by frequent spraying of the plant if hoya does not dry out for a long time and lives in a greenhouse.

    Fungal spores are spread by raindrops, insects, wind. Lack of potassium and phosphorus in the body of ivy contributes to the disease.

    To effectively deal with anthracnose, regularly steam the soil of the plant, reduce the humidity of the air, destroy the affected leaves, spray hoyu with preparations “Kvadris SK”, “Hom”, “Strobe”, “Abiga-Pik”.

    Root and stem rot

    With this disease, hoya stops growing, the leaves dry out and fall off, then the root decays, and the plant dies. At first it seems that hoy just does not have enough watering, but after normal soil moisture it becomes clear that this is not the problem, the leaves continue to dry out and fall off.

    It is very difficult to identify the disease at an early stage, because the wax coating on the leaves makes them look healthy for a long time, and the root rots quickly. Lesions on the stem can be dry and wet. Rotten roots are black or gray. They can also be wet or dry.

    In order to prevent and treat rot, the soil should not be too wet.especially if the room has a low temperature. The soil for planting needs to be sterilized. In case of a rot disease, the affected plant is treated with Kuproksat, a colloidal sulfur or Bordeaux mixture, and if these funds do not help, ivy will have to be destroyed.

    Cortical growth on the leaves

    This disease manifests itself by fading leaves and gray bloom; a crust forms on the inside of the leaf. The startled escape stops growing, but if you take the necessary measures in time, then hoya will survive. Further growth of wax ivy can slow down, and a new shoot will start moving next season. Hoya leaves will continue to be healthy if all conditions of detention can be met.

    The sequence of treatment of this disease: First, waxy ivy leaves should be rubbed with alcohol, then sprayed with “Hom” or “Ordan”. After processing, place the plant in a warm place.

    Gray rot

    This fungus affects all green parts of the plant. On them brown spots with a greenish or gray raid will be visible. After some time, the spots will look like dry rot, necrosis of blood vessels and tissues will occur. The affected parts of the plant die off.

    The fungi that cause this disease are wound parasites. They get inside the stalks and leaves through the wound. Also these mushrooms like musty air. Disputes are spread by wind, dirty tools and precipitation. Favorable temperature for the development of the disease - 17-25 ° C.

    The ways to combat and prevent this disease are as follows: disinfect working tools and soil, air the room and reduce humidity. Do not forget about the lighting - hoya should not grow in a dark place.

    Black fungus

    A black fungus settles on the secretions of aphids, powdery worms and whiteflies. It is a dry plaque that is not life-threatening to the plant, but clogs the pores of the leaves, which is why hoya “does not breathe”, stops growing and weakens.

    Treatment is to destroy pests. Wipe the flower with a damp cloth dampened in soapy water and then treat it with a fungicide.

    Mealy dew

    This disease is quite rare in domestic hoi. More often it is faced by those who grow this plant in greenhouses or in the open air. Leaves appear little white loose spots that can be easily wiped off. But if nothing is done, the spots will grow until they occupy the whole area of ​​the sheet.

    The appearance of powdery mildew contributes to moist air, excess fertilizer with nitrogen and strong temperature drops.

    Prevention and treatment: in case of a weak injury, tear off the diseased leaves and normalize the conditions of detention. If the disease is in its advanced form, use the preparations “Kvadris SC”, “Topaz”, “Tiovit”, “Bravo”.

    Downy mildew

    Another name for this disease is peronosporosis. Hoya is rarely affected by this disease. They suffer, as a rule, ivy growing in greenhouses and in the fresh air.

    On the leaves appear yellow spots, which eventually change color to brown. On the underside of the leaves gray spots are formed, they then turn into black dots.

    If you let everything take its course, inevitably yellowing and falling leaves, and the causative agent of the disease will fall into the vessels of the plant, which will lead to wilting hoy.

    Prevention and treatment: Be sure to disinfect the soil before planting, air hoyu and timely remove diseased leaves. In case of a disease, treat the lower part of the leaves with the preparations “Ordan”, “Khom”, “Kvadris SK”.

    Black spot

    The spots on the leaves that appear in this disease are shiny and bulging. They are called - stroma. How the stroma will look depends on the pathogen. But despite the slight differences in appearance, they all develop rapidly in high temperature, high humidity and poor lighting.

    Treatment: spray the diseased plant with the preparations “Kvadris SC”, “Abiga-Peak”, “Maxim”.

    Symptoms of the disease: spots of red, yellow or orange appear on the top of the leaf, and on the inside there is a congestion of brown and orange spores. The leaf turns yellow, dries and then dies off. The disease spreads and progresses at high humidity and a temperature of 10-20 ° C.

    Prevention and treatment: It is not necessary to spray hoyi species that are susceptible to rust, because the water droplets on the leaves contribute to the maturation of the spores. When watering it is not necessary to wet the aboveground parts of the plant. If hoya is sick, remove the affected leaves and spray the plant with Vectra, Kuproksat, Topaz, Vectra or Bordeaux preparations.

    Favorable environment for the fungus, the causative agent of this disease - wet and cool weather. The disease begins with the roots, and then spreads throughout the plant. Leaves form gray or colorless spots with spores in the middle. Then the leaves die off and fall off.

    Prevention and treatment: conduct ground disinfection "Fundazol". After that, treat the plant with a preparation containing copper, and isolate the hoyu for the duration of the treatment. All other plants that were in contact with her, process. Leaves on the diseased hoi remove to prevent the reproduction of fungi.

    Fusarium wilt

    The disease proceeds in one of two ways: only the stem can wither or even rot the roots.

    In the affected wax ivy, they first lose the turgor of the crown and then the escape. The vessels are clogged, become dark at the cut of the stem. To save the plant, it is necessary to cut off and root the top of the shoot. At the onset of the disease, the large roots remain healthy, and the small ones rot first.

    If the soil and the air are wet, and the temperature is above 18 ° C, then the disease is very active.

    How to deal with the main pests of hoy, methods of dealing with them

    Hoihe diseases provoke fungi, bacteria, viruses, pests and various external factors. Diseases can also occur as a result of improper care: Increased heat and humidity contribute to progressive carbonaceous diseases, and insect parasites do well in hot and dry conditions.

    In the fight against tick and whitefly will help the drug Sunmite. It is effective at all stages of pest development and is not addictive. The drug starts immediately after its use and remains active for one and a half months.

    From shchitovki, mite, thrips, whitefly and aphids have proven themselves well Aktara and Actofit. Chervtsov is best removed by hand with a brush dipped in alcohol and spray the affected parts of the plant with preparations based on light oils. Well help and a mixture of drugs "Mospilan", "Confidor-maxi", "Aktara" on 1 mg. Each drug must be diluted separately in 330 ml of water, and then mix everything.

    To radically get rid of the poduras, you need to dry the soil, and then sprinkle it with tobacco dust or lime.
