Yellowing the leaves of cicas is a common problem that, in most cases, can be easily fixed.
The most common causes are:
- The lack of trace elements.
- Nitrogen deficiency.
- Low illumination of the plant is for light-loving species, high intensity of illumination is for shade-loving.
- Damage to the root system.
The lack of trace elements occurs for two reasons:
1) cycadite was not fed with fertilizers containing microelements, and he had nothing to digest, this situation begins to manifest somewhere six months after the acquisition of the plant.
2) tsikas were fed with microelements, but due to the fact that the plant is contained in the cold, or due to the fact that the acidity of the soil mixture went beyond the recommended range, the trace elements are no longer available for the plant. This situation manifests itself after the tusk was watered with hard water for a year or more.
In the first case, it is enough to feed fertilizers with trace elements, and already new leaves will develop without yellowing. In the second case, transplantation with partial or full replacement of the soil mixture is necessary, and the plant content in the recommended temperature range.
Low (High) Illumination
For each type of cicasas, there are optimal parameters for the intensity of illumination. In order for the leaves to turn yellow, the light intensity should be very different from the recommended. As a rule, this happens in the spring with a sharp increase in the intensity of illumination, or if the plant is taken out of the room to the street without quenching.
Root system damage
The most common causes are:
- the plant has not been watered for a long time,
- the plant is often watered,
- root system supercooled,
- roots suffered from a high concentration of fertilizer with a one-time feeding.
The video shows one of the options how to solve this problem.
Should I worry?
First of all, it is necessary to find out whether there is a dormant period for cicasum, which begins in late autumn and lasts until the beginning of spring. Being a tropical plant, the cicas does not shed the foliage, but it ceases to grow and does not throw out new leaves, that is, the vegetation stops. During this period, a slight yellowing of individual sheets is possible. If the old leaves located at the trunk become yellow, then they dry out and fall off - you can not worry, as this is a natural process of getting rid of old leaves, after which fresh, young leaves will appear on the plant. In this case, cicasus can be helped by removing all the old parts of the plant.
Improper care as a cause of yellowing
The most common cause of yellowness on the leaves lies in the wrong care, and there may be many reasons for this:
- poor lighting
- insufficient or excessive watering,
- pest attack and disease infection
- lack of dressings.
The tsikas needs top dressing only in spring and summer. During this period, fertilizers must be applied every two weeks. It is best to choose organic fertilizers, for example, you can use mullein, diluted in water. In the winter time for the plant comes a period of rest, so fertilizing should stop.
Putting the pot on the balcony, on the windowsill under the open window or next to the open window, you also risk getting yellow on the foliage. The fact is that the plant does not tolerate drafts even in the summer, and even more so in low temperatures in winter. What to do in this case? The answer is obvious - the flower pot must be moved to a place protected from drafts, but it must have normal air circulation. In winter, the temperature in the room should not fall below 12 ° C, otherwise the leaves will also become yellow, begin to curl, then dry out completely and fall off.
The heat-loving southern plant needs enough light for normal development. Obviously, poor lighting is another reason why the cyclone turns yellow. The best location for it will be a place in a spacious room with good lighting, the windows of which face south, southeast or southwest. Illumination must be diffused - tsikas also can not tolerate direct sunlight. If the flower is placed in the garden, on the veranda or terrace, it is necessary to create a penumbra. However, remember that the plant needs time to adapt to the new light, so a gradual change in the amount of light is recommended. It should be borne in mind that tsikas tend to asymmetrical growth, so periodically it should be turned the other side to the light. The number of light hours per day should be at least 12-14. In winter time (from November to the end of March) the lack of lighting can be filled with fluorescent lamps and phytolamps.
Lack of moisture
The main rule when watering - regularity and moderation. The soil in the pot should not dry out completely, so as soon as it dries to half (at least 2-4 cm), the soil should be moistened. In the summer, this should be done about once a week (sometimes every 5 days). Water for irrigation must be defended for at least 12 hours, preferably a day, heated to room temperature. In winter, in the dormant period, the frequency of watering is reduced, but the plant still needs moisture, so watering is done 3 times a month. However, it should be taken into account - if the period of rest is weak or not expressed at all, the moisture regime can not be changed. Also, in winter, it is necessary to avoid close proximity of the flower to batteries and other heating devices - this can cause yellow edging on the foliage.
High demand for moisture is often experienced not only by the root system, but also by foliage. Therefore, it is desirable for the plant to arrange a “shower” - the stem part and the roots should be covered with a film or other waterproof material, and the green part of the flower should be generously sprayed with a spray bottle. Such bathing can be arranged for cicasus once every few days. If it is not possible to use a spray bottle, at least wipe the leaves with a damp cloth. Excessive dryness of the air can be eliminated in this way - pour river sand onto a wide pallet, pour water on it and install a plant on it or next to it - moisture from the sand will evaporate and moisten the air in the room. Instead of sand, you can use peat or expanded clay. There is an opinion that in the stem part of the plant accumulates water, but this is a myth, therefore regular hydration for cicas is vital.
Excessive watering is another reason why the cicasum may lose its green tint, most often from the base of the leaf. Excess moisture is dangerous not only by the yellowing of the foliage, but also by the decay of the root system, which will inevitably lead to the death of the plant. The water in the pot should in no case be stagnant.
Yellowing due to pests
Cicas rarely suffers from pests and diseases, but is not completely protected from them. If all of the above reasons are eliminated, and the leaves still continue to turn yellow, you need to inspect the plant for infection by a small parasite - a shield. Typically, when the disease begins, the foliage begins to turn yellow from the tips, and the plant itself is wrapped in fluff or cobweb. All pests and especially their eggs must be removed from the plant, and the foliage itself must be treated with special preparations: Aktellik, Phosbecid, Aktara, Bankol. You can also use safe folk methods:
- soap solution (you can add alcohol),
- an infusion of pepper, garlic or onion,
- kerosene (it can also be added to the soap solution).
Tsikas Revolyuta (drooping cicas)
Tsikas Revolyuta (drooping cicas)
The leading position is occupied by the Revolution band, actively cultivated at home. The plant is compact, therefore it is in demand among gardeners. If in the external environment this type of cicas grows up to 6 meters high, then in the room an adult cycad within a year forms no more than seven new leaves. Such decorative culture is very convenient to grow even in a small room.
Cicas has a drooping stem in the form of a column, whose height is 45 - 55 centimeters. At the top of the stem is the crown of palm-like or fern leaves. The foliage of a young plant is soft, pubescent, with time it will become harsh, glossy.
Cones form at the top of the stem. Female-type cicas has densely pubescent yellow or reddish foliage. Cones loose structure. Cycadus drooping male type with brown cones, tightly fitting scales.
Tsikas Revolyuta is an ornamental houseplant, it is considered to be a living decoration of apartments and winter gardens. It is not so easy for beginning flower growers to grow this representative of flora. To do this, it is necessary to study in detail the care of a plant at home at various stages of development.
This name was obtained because of the curved leaf shape, the upper side of which is glossy, shiny, and the bottom - matte. He comes from Madagascar and India.
From this culture, sago is obtained by removing it from the stem core. Sago is considered a valuable product for the population of many countries.
Cicas sickle unpretentious to temperature conditions. Loves well lit places indoors. Watering is moderate, in winter - insignificant. Replant the plant every five to seven years, if the size of the pot has become small. Propagated more often by seeds in the spring. You can propagate by cuttings that are formed from side shoots. The cuttings need fertile soil and the temperature in the room is not lower than + 25 °.
Ulitkovikovy zikas (curled)
Ulitkovikovy zikas (curled)
Australia and India are considered to be the homeland of the plant. Ulitkovy cicas is characterized by large dimensions. Its trunk is in the form of a column, reaching a height of up to three meters. Leaves 1–2 meters long are collected in bunches. Cone-shaped tip appears in any month of the year. The number of leaves in it is different: 15 - 26 pieces (depending on age and temporary season). Young leaves grow vertically, becoming large, begin to bow to the ground, lying horizontally.
The beauty of this representative flora lies in the feathery, large leaves, divided into many narrow leaf-slices attached to the central vein. Such a narrow-lanceolate segment has a length of 25 cm, its width reaches 1.5 cm. The segments are arranged densely towards each other. On the central vein of the main leaf there are short spines.
This type of cyclotar is propagated by seeds and vegetatively. Side shoots appear all year round on the trunk of an adult plant.
Zikas curled is a decorative, evergreen perennial. Very much appreciated in the tropics and subtropics. The elegant plant is especially popular in Florida.
The homeland of the plant is Madagascar. Cicas is widespread in Kenya, Tanzania, Mozambique, Comoros and Seychelles. Prefers sandy soil, likes to grow on coral formations. Under natural conditions, it grows about 10 meters. The average height of a tree stalk is usually 4 meters. The top often forks.
Foliage length from 150 to 210 centimeters, has a dark green color, semi-gloss. Pollen ripens in buds of oblong orange or brown color. Seeds are large, reaching the size of a goose egg (50-60 mm).
Indochina is the birthplace of Siamese cicasas. Now it can be found in Thailand, southern Vietnam, in the forests of Burma. About the plant, we can say that it is miniature - the height does not exceed 2 meters.
The trunk is in the form of a tuber: the lower part has a thickening, from the middle to the top - narrows, becoming much thinner. Thorny, scrubby yellowish petioles covered with pinnate leaves. The leaflets on them are narrow, pointed, of medium length, about 10 cm, and 5 mm wide. Leaf color is bluish-white.
The highest plant of the family of cycads. The trunk, like a column, grows up to 15 meters in height. Leaflets of a linear shape, 30 cm long, 2 cm wide, are densely located on the petioles, form pinnate leaves two meters long. The leaves grow both symmetrically and in bunches; from afar, Rumph's tsikas seem unkempt. This cycad grows faster than all their relatives. It lives on the shores of the island of Java, as well as the Andaman, Nicobar. Sri Lanka owes its origin.
How to care for cicasus at home?
Zicas - an unusual plant, attracting the eye. It is pleasant to flower growers to dilute the collection with an original plant with century history. It is no coincidence that its value is higher than other flowers grown in indoor conditions. It will be comfortable to feel the cycad in the spacious hallways and halls that have good lighting and an appropriate temperature.
You can grow it in open ground, if the climate is favorable, not harsh. Any amateur grower can grow a tusk at home, if properly cared for.
Zicas in its natural environment does not grow on the most fertile soil. A plant that came to us from the tropics, on the one hand, needs a large amount of organic matter in the soil, on the other, it does not particularly require additional mineral additives. Cycadite like fertile subacidic soil with good drainage. Suitable substrate for palm plants.
You can prepare a light soil mixture on your own, using peat and sand base, humus, sod and leafy soil. All take in equal amounts.
It is important to properly lay the drainage to ensure good moisture permeability, without water stagnation. Expanded clay or pebbles must be distributed over the entire container for planting, and not just poured into the bottom of the pot. This method will allow excess moisture to seep into the pan.
Watering and moisture
The cicas plant is naturally habitual to droughts, so care at home must be adapted to the natural. Water less often, but more abundant! Let the soil dry out almost completely between the irrigations, then moisten it well and abundantly with an earthen clod, and half an hour later - drain the excess water from the sump. Regarding the frequency of watering need to focus on temperature and lighting. In the summer, in hot and sunny conditions, the cycad is often thirsty, and in winter, in a state of rest, when there is a shortage of sunlight, the palm tree drinks less water. Both excessive moisture of the soil and its long overdrying are harmful to the plant! 8 rules for watering indoor plants.
Zicas revolyuta is picky about air humidity. Since it grows in nature mainly in tropical wet areas, it is necessary for the house to provide higher humidity by regular spraying. In dry air, the tips of the leaves turn yellow and dry! Sheet feeding - recipes. Large leaves can be wiped with a damp cloth to rid them of dust, or arrange a periodic warm shower for the plant, protecting the potted soil and palm trunk with a package.
Fertilizers and fertilizing
Feeding a palm tree, remember that a lack of fertilizer is always better than their excess! The concentration and frequency of dressings are directly dependent on the lighting. Usually during the period of a hot summer that is active for a plant, it is fertilized according to the instructions once every three weeks, in the spring and in the autumn 1/2 doses of fertilizer are sufficient once a month, and in the winter it is not used at all.
In the "diet" of the cyclotron must be present trace elements, their optimal ratio - nitrogen (N): phosphorus (P): potassium (K) - 3: 1: 3, or 3: 1: 2. Deficiency and excess of trace elements in the soil. In addition to the mineral dressings, the cicas home perceives organics well, which can be alternated. Organic for indoor plants.
Requirements and necessary conditions
In the natural environment of the Pacific tropics, these majestic members of the sago palm trees are prone to slow development. During the year they can grow up to three sheets and grow a little. And in room conditions, the height and number of feathery stems practically does not change.
With proper care and a properly selected location, the flower will annually please the owners with a new leaf, gradually increasing the lush bright green fan. Попробуем разобраться во всех тонкостях этого капризного экзота.
Саговая комнатная пальма предпочитает хорошо освещенные теплые зоны, поэтому для нее нужно подыскать в доме самые яркие места. Желательно, чтобы свет согревал листву на протяжении 8–10 часов в сутки.
In summer, the pot with the plant can be transferred to the sunny balcony or loggia, and in winter it needs additional lighting.
If it does not provide the necessary illumination, the foliage will stretch greatly and lose its uniform pinnacle, which will undoubtedly affect decorativeness. Moreover, in the shadow of the cicasas stop growing.
But do not overdo it with ultraviolet. Direct sun rays, as a rule, leave behind severe burns on delicate sheet plates. To prevent this from happening, place a flower in the southeast or southwest side of the house, where there is a lot of ambient light.
And in order to evenly develop the crown of your palm, periodically turn the pot.
Cycadite will be grateful for the acidic fertile substrate and good drainage. These are the main requirements of the plant to the physico-chemical characteristics of the soil.
For this variety of palm trees experienced flower growers are advised to use light soil mixed with river sand and top peat. The classic variant for cicasum consists of equal portions of raw peat, humus, hardwood and river sand (perlite can be added as an alternative). In addition, the ground should be drained throughout the volume. It will be wrong to simply fill the pot with a small layer of expanded clay when planting - it must be evenly distributed over the entire planting container.
Such a structure will allow excess moisture to drain into the pan, just make sure that there is a hole in the pot. If you do not have time to mess with the preparation of soil mixture, you can use the purchased soil for palm trees.
Many people like Zikas, but having heard of his demands, beginners stop their ardor, because they do not know how to care for a flower in an apartment setting. Experts say the need for elemental irrigation, fertilizer, foliage hygiene and transplanting.
There are always plenty of moisture and heat on the native tropical coasts of cicasas. But despite its origin, capricious exotus can withstand a short drought and does not tolerate excess water at all.
Abuse of these qualities of the cycad is not at all worth it, otherwise it will wither. Professionals in horticultural affairs are advised to water the plant when an earthen ball in a pot is half dry.
Please note that the moisturizing process is different from the classic watering. First you need to pour a large amount of defended non-cold water under the root to soak the substrate.
Then, when excess liquid is drained into the pan, repeat the procedure, this time in order to fuel the entire root system. The rest of the water from the stand under the pot must be drained, because fungal spores and mold can start in them, which will inevitably lead to the death of palm trees.
If you do not know the preferences of this plant, it is easy to destroy illiterate feedings. To fertilizers tsikas extremely demanding.
In order not to harm the plant, it is important to remember the main rules:
- Feeding should be done once a month, starting from the period when the tsikas will come out of hibernation (from spring to autumn).
- Palma reacts poorly to complex mineral fertilizers.
- For the pot recommended exclusively organic without magnesium and potassium salts.
- Ideal for horse bones are horse manure and mullein solutions.
- When feeding, be sure to consider the ability of the plant to absorb the introduced substances. And remember that in this case it is better to underfill than pour.
Pruning and care of leaves
Growing a sago palm tree does not provide for permanent duty with scissors in hand to remove all the excess or to form a crown. In this case, it will be necessary to periodically cut off the lost attractiveness and slack leaves.
They are easy to see in an atypical shape and color, and dying specimens often drop down, lying in a horizontal plane.
When growing cicas at home, only young specimens need transplantation, which the former planting capacity has become cramped. Experts advise to carry out this procedure every three years.
But if the palm tree began to intensively increase biomass and threw out new leaves, you need to wait. Wait until the foliage is stronger, because the season of transplants lasts from spring to autumn.
Remember that cycads are always better developed in slightly cramped vessels. Therefore, do not rush to transplant them. This is done only with the apparent discomfort of the flower.The new tank should be deep and 2–3 cm wider in diameter than the palm trunk. Accordingly, the ideal proportions of the pot are approximately as follows: with a diameter of 15 cm - a depth of 30–35 cm.
Before starting a wet earthen clod with cicasum, remove a third of the foliage on it. Always start this process from the bottom, removing old branches. Act very carefully and protect the root system of the exotic from any damage.
Carefully disinfect all inventory and utensils, otherwise the plant may become infected with putrid infections.
Successful cultivation of this variety of palm trees requires not only patience, but also certain knowledge and skills. Unfortunately, in the reviews about the culture, flower growers are increasingly discussing all sorts of problems that arise during home cultivation of a flowerpot.
In some cases, their cause is the inexperience of the owners, in others - a violation of the rules of care and disregard for the demands of the cyclotron. Consider the most common questions and answers to them.
Rotting of the lower part of the trunk and roots
The problem is expressed by softening the lower part of the trunk. Dirty-brown spots are clearly visible on it. When digging, black or dark brown areas on the roots are noticeable.
Such a flower can be saved by cleaning from all affected areas, their disinfection and transplanting into a new container. At the same time, when you get the affected plant from the old pot, completely shake the ground from the roots, carefully inspect them and cut everything that has died off to the living.
Then treat the affected area with fungicides ("Fundazol", "Maxim", "Home", "Skor"). Then cover this place with garden pitch, paraffin or wax. Saturate healthy roots with “Kornevin” or “Emistim”, “Heteroauxin”.
It is better to transfer such specimens to full recovery to perlite. This can take from 3 to 6 months or more. If the flower began to give new root processes, the rot ceased. Otherwise, repeated cleaning and disinfection may be necessary.
Rotting top of the trunk
If you notice a darkened soft top of the palm trunk, it means that the disease completely destroyed the base of the pot. In such cases, the infection affects the foliage - it becomes brown, falls to the floor.
In most cases, the sinus can not regenerate dead tissue and dies. But do not rush to throw it away.
To begin, remove all softened affected areas, capturing a few centimeters of live fibers. Spread the roots and trunk generously with any fungicide, then cut the surviving cicas base tissues into plates and place them on raw agroperlite. Chances are high that young shoots will appear.
Light spots on the leaves
In such cases, you need to revise the frequency and composition of flower dressings, and also pay attention to the conditions of its maintenance. Perhaps he lacks light or cold. The reason may lie in the elemental lack of nitrogen.
Dry leaves and yellow leaves
This pattern is often observed when the plant does not receive the required nutrients. Then the old leaf plates give up their resources to form new shoots and die.
But the reason may be hiding in an overdose of fertilizing. If such a “sinner” was noticed behind you, do not wait for the problem to be solved by itself, but immediately rinse the soil. And better transplant a palm tree.
Also review all the nuances of flower care and the ratio of existing conditions with the necessary requirements of cicas.
New leaves are shorter than old ones
This problem is quite expected when conditions of detention were drastically changed for the worse. For example, you moved the pot from the sunny side to the shade. Palma did not have time to adapt, this process coincided with the build-up of a new escape, and as a result you got a very unattractive picture.
The reasons may also be exhausted land in a pot, lack of food or its excess. In any case, the need to adjust the care and conditions created for the plant.
New leaves do not grow
Every year the cycad must release 1–2 leaves. In their absence, you should pay attention to the temperature regime, which contains a pot, its lighting, the frequency of watering and fertilizing. And also inspect the trunk for trunk rot. Now all the secrets of this beautiful, but, alas, naughty flower are revealed to you. Learning what to do when the leaves turn yellow and fall on the cicasus during care at home, the base is rotting, there are no new shoots, do not be afraid to start it.
If you follow all the above recommendations, be calm - the sago palm will not disappoint you, but on the contrary, from year to year will increase its emerald crown for decades.
