Having noticed sticky drops on orchids on leaves, many flower growers panic. This phenomenon is not so frequent, and therefore is perceived by many as something terrible and out of the ordinary.
Is the appearance of sticky droplets dangerous? Does it signal orchid disease? How to understand why orchids have sticky leaves, and what to do? We will answer all these questions in our today's article.
Sticky orchid leaves phalaenopsis
If sticky drops appeared on the orchid, you need to determine the cause. And it can be completely different. And in one case it will be completely natural, and in the other it will require serious measures.
Above all, do not rush to wash off the sweet droplets, disturbing the flower once again. In any case, it will not affect the result in any way, but the overall picture may blur. Droplets can be more or less, appear on the peduncle or leaves, be above or below. However, it is always possible to find secondary signs of the disease, if present.
Drops on an orchid are usually transparent, regardless of the causes of the appearance. They are sometimes called sticky dew, for similarity, with transparent morning dew. At the same time, the liquid on the leaves of phalaenopsis is always sticky.
If you look at the flower more closely and carefully, you can find or not find other symptoms. Based on this, it is possible to draw conclusions whether the orchid leaves are sticky, with some kind of disease, or sweet droplets are quite normal.
Next, we describe the very symptoms, depending on the origin of the sticky droplets.
The natural process of the appearance of sticky droplets on the leaves
This may seem strange, because by itself, the phenomenon is rare, but indeed, it can be quite normal in orchids.
And it is connected with the fact that in the wild, orchid requires pollination. Is there really a better way to attract pollinators to insects than sweet nectar? Of course not! Here is the orchid and begins to allocate sweet droplets to lure insects to their flowers.
In nature, everything is arranged very well and orderly, and in orchids as well. However, it is sometimes difficult to isolate a pattern. It’s impossible to understand why the orchid didn’t do that before, and now decided to isolate nectar. But the fact remains.
How to understand that this is the case? Carefully inspect the plant. Do not miss anything. Examine the leaves very carefully on both sides. Inspect the peduncle and the flowers themselves. Inspect the root system as far as possible. You should be alerted by the presence of spots on the leaves. And maybe you will find pests. If the flower is all right, then nothing to worry about. Sticky drops on the leaves of an orchid in this case are quite natural. Leave stickiness, and do not take any measures.
As we said above, a disease or other problems will always have more than one symptom. Determine that the plant suffers from excess moisture can be when the orchid sticky drops on the leaves are accompanied by spots. This should immediately alert.
To check whether the case is really watering, look at the substrate, most likely it is too wet. But, it would seem, overmoistening occurs frequently, but there are no sticky drops. And this in this situation will be an explanation. Pay special attention to environmental factors. Surely, the indoor temperature is not as high as required for the flower. And there is an orchid on the window, or under the lamp itself. Coolness, bright light and overflow are the combination of circumstances when an orchid produces sticky drops.
In such a situation, you must first reduce the lighting. But, of course, no need to put a flower in the shade. It is enough to move a little away from the window.
The second step will require replacement of the substrate. You can, of course, dry the old one, but the risk is great that in it, under such unfavorable conditions, microbes and fungi have already begun to be diluted. Therefore, the replacement, at least part of the substrate will be more appropriate.
You can use vitamin cocktails for the speedy rehabilitation of orchids.
It manifests itself almost as well as overflow. There are sticky drops on the orchid and spots. To determine the true cause can only be knowing whether you could overdo it recently with fertilizers, or whether it was just watering. It is almost impossible to distinguish one from the other.
If you suspect that the matter is in dressing, then you need to immediately begin transplanting the flower. And it does not matter whether it is blooming now or not. If you postpone the transplant, then you can completely lose the plant.
The case in the structure of the root system. Its upper layer consists of hollow cells, which like a sponge absorb moisture and nutrition. With an excess of moisture and fertilizer, this layer becomes clogged and the roots rot. And it happens so fast that sometimes the owner does not even have time to identify the causes, and the root system has almost died.
Starting the transplant, you need to wash the roots in clean water, and then slightly dry. After that, plant a flower in a thoroughly washed pot, and do not water it for at least a week. Top dressing is generally better to exclude in the coming months, or until the next flowering.
Recall also that using universal flower fertilizers for epiphytic orchids. the dosage specified in the instructions should be reduced at least 3 times. And some flower growers are advised to cut it 10 times.
Unknowingly, it can be decided that droplets are the product of pests. But in fact, everything is much more amazing. The orchid makes the sticky leaves itself to protect itself from uninvited guests. This seems incredible, and makes you suspect the presence of intelligence in the flower. But in nature, everything is so arranged. Even a plant can resist pests. More often such droplets are concentrated on the inside of the leaf, although they can be located anywhere.
What is it for, and how does it work? Elementary. Insects crawl on the sweet nectar, and just can not get out. Approximately by this principle work traps for flies.
What should be done in this case? Of course, start immediately ridding the orchid of pests. Depending on who you find during the inspection, use either special preparations or hot showers.
In any case, it will be necessary to replace the substrate, that is, to transplant the flower. Otherwise, you risk leaving pest larvae in the ground, and repeat everything again.
For some fungal diseases, droplets on the leaves are also characteristic. For example, powdery mildew manifests itself at a very early stage of development. If, in addition to drops, you began to notice white bloom, then you need to apply the fungicide as soon as possible to avoid serious consequences.
In addition, it is good to spray a flower with vitamin B6, which has a positive effect on the health of the flower, and also protects against fungi and pests.
Prevention of the formation of sticky droplets on the leaves is no different from the prevention of any other disease. The first step is to observe the conditions recommended for these plants. And in the second, do not neglect regular inspections and treatments. After all, orchid leaves, like roots, immediately signal if something goes wrong. Then your orchid will be healthy, and you will not have a question why sticky droplets have appeared on the orchid.
In addition, do not forget about the special vitamin shakes for orchids. You can easily cook them yourself, while the flower gets a huge benefit from it. Unlike fertilizers, which simply provide nutrition, vitamins ensure the harmonious and active development of the orchid. They increase the immunity of the flower, and hence its overall resistance to various diseases. With vitamin supplements, the flower will be much more painless to tolerate both planned transplants and some unfavorable conditions. After all, it is clear that anything happens, that it is impossible to guarantee a constant temperature and humidity, and to maintain the substrate in perfect condition. But the vitamin complexes with vitamins of group B, succinic acid and glucose in the composition, will allow the flower to successfully cope with difficulties.

Why does the plant release fluid?
When a fluid protruding on the surface of a plant is detected, it is worthwhile to take the following actions in order to reveal what caused this:
- measure temperature and humidity
- level of his aspiration,
- it is also necessary to eliminate the factor of the harmful effects of direct sunlight and excessive watering,
- isolate the orchid from other flowers and conduct a thorough inspection of each leaf, peduncle, rosette and substrate.
Usually, parasites can be seen with the naked eye or with a magnifying glass - directly inside the viscous droplets, on the reverse side of the sheets, and also in the tubercles tucked in webs. If there are no traces of damage, and the conditions of orchid maintenance are close to optimal, then, most likely, there are no reasons for panic.
The isolation of nectar in this case is a natural process of transpiration. In the opposite case, it is necessary to take measures to improve flower care and pest control.
What to do?
In the case when the viscous droplets signal the presence of problems, it is necessary to revise the principles of orchid care. Principles of Orchid Care:
- Replace watering by dipping the pot (up to the level of the barrel) in a bucket or basin with water for 15-20 minutes. The procedure is carried out once every 2 weeks. In addition, it is recommended to add fungicide tablets to the 1-2 capacity, for example, "Alirin-B".
- Reduce moisture intake in winter - excessive moisture only creates favorable conditions for the reproduction of pests. The sure signal to water a flower is to dry the roots.
- In the summer, the plants should not be allowed to dry out: spray orchids from a spray bottle and organize watering from the shower with warm enough water.
If a viscous substance on the surface of an orchid is a symptom of infestation by parasites, then measures should be taken immediately. Prevention measures:
- With a powdery mealybum lesion: cut off infected flowers, wipe the leaves on both sides, the window sill and shelves for plants with insecticides, diluted in accordance with the instructions ("Fitoverm", "Aktara"). It is also desirable to completely replace the substrate.
- In the presence of aphids: daily, mechanically treat the diseased areas with soapy water (1 briquette of laundry soap per 5 liters of water) or resort to using special preparations, for example, Fozalon, Phosphamide.
- Attacks: remove dry and yellowed leaves and flowers, and treat healthy parts of the plant with an oil solution (2 tablespoons of olive oil per 1 liter of water), fresh garlic juice or insecticides such as Permethrin, Arrivo.
Chemicals can be hazardous to human health. It is worth working with them in protective gloves and a mask, and also to keep away from children and pets.
Thus, the concern of florist due to the appearance of sticky drops on orchids is not always justified. This phenomenon is often a natural process for the synthesis of flower nectar. At the same time, such dew is a sign of danger to the plant. Attentive inspection of the flower as well timely application of preventive and curative measures is a guarantee of beauty and health of the orchid.
