Orchids are considered quite capricious houseplants that often get sick. Florists know this and are always in service.

But noticing sticky drops on the leaves of phalaenopsis, many of them panic, since this phenomenon is quite rare.

What does it mean and how to deal with it, as well as what preventive measures are there? You will learn the answers to these questions and much more by reading our article.

What are these drops and how they look: description and photo

It happens that drops appear on the leaves of phalaenopsis, outwardly resembling dew, they are sticky to the touch, and they taste sweet. They can be of different sizes and located in different parts of the flower. If you take a closer look, you can see the sugary structure.

Reference! This phenomenon has a scientific name - transpiration.

In the photo you can see how the drops look on the leaves of the plant.

Causes of occurrence

If you find such droplets on your indoor flower, you need to quickly determine the cause of their appearance. In one case, immediate measures will be required to save the plant, in the other, this is a natural process.

Sticky drops can appear for a variety of reasons:

  1. Natural process - flower nectar attracts pollinating insects or, conversely, serves as a trap for insect pests.
  2. Excess watering - the accumulated moisture oversaturates the flower, and he gets rid of it by evaporation through the leaves. If you add bright lighting and low temperature to improper watering, then this will be the answer to the problem.
  3. Damage by harmful insects - with poor immunity, the plant can be attacked by pests such as aphids, worms, ticks or scale insects. They feed on the sap of the plant and the sticky layer is a kind of signal for help.
  4. Disease affections - sticky drops indicate such an infectious disease as powdery mildew. Another sign of the disease is that white bloom or black fungal spores are visible on the leaves of phalaenopsis.
  5. Excess dressing - with excessive use of dressings, an exotic flower increases its metabolism and it tries to get rid of excess sugars caused by the use of fertilizers, releasing nectar in the form of a sticky layer on the leaves.


The success of treatment depends on the correct diagnosis of the phenomenon, therefore before starting the measures to restore the health of the flower, it is necessary to conduct a thorough visual inspection:

  • If, in addition to the sticky layer, white bloom or black spots are also observed on the leaves of phalaenopsis, this is a sign of powdery mildew.
  • Yellow spots on the leaves indicate an excess of mineral fertilizers.
  • It is also necessary to inspect the reverse side of the sheet. If the reason for the appearance of sugar drops lies in insect pests, they should be looked for there.

When is there reason to worry?

If an exotic flower grows and develops well, then the reason for the appearance of sugar drops is physiological and you shouldn't worry about it. However, when the accompanying signs described above appear, the plant must be rescued immediately, otherwise it will die.

What to do if stickiness appears?

Having understood the reasons for the appearance of sweet drops, you should proceed to decisive actions to save the plant. The complex of rehabilitation measures depends on the cause.

Due to a sudden change in care

Orchid is a demanding and capricious plant, therefore, when the conditions of care change, it experiences stress, and tries to draw attention to itself with the help of sweet dew.

We check whether the optimal conditions for keeping phalaenopsis are met:

  • comfortable temperature and humidity in the room;
  • no drafts and sudden temperature changes;
  • the flower should be on the sunny side, but in no case in direct sunlight;
  • minimal watering in winter.

If the storage conditions are violated, the flower will not be able to develop fruitfully and will signal this with a sticky layer on the leaves.

To protect against insects

To protect against insects, the orchid produces sweet nectar that attracts them. Pests stick to it and die.

But sometimes sticky drops can be traces of pests that have settled on the back of the leaf and feed on exotic juice.

To solve the problem, follow the steps:

  • remove an infected plant from healthy ones;
  • remove insects with a cotton pad;
  • trim the affected areas as needed;
  • wipe the leaves with soapy water;
  • if this does not help, spray with an insecticide solution, for example, Fozalon or Phosphamide.

When the threat has passed, the plant can be returned to its place.

To attract insects

Another natural physiological reason for the appearance of sweet drops on an orchid is the attraction of pollinating insects.

If the plant looks healthy, there is nothing dangerous in the appearance of sugar syrup on the leaves. and no treatment is required for the plant.

Due to illness: plant treatment

If phalaenopsis is infected with powdery mildew, there is no time to waste.

Infection actions:

  • isolate a diseased plant;
  • rinse phalaenopsis with warm water;
  • give it time to dry;
  • treat with drugs "Aktara" and "Aktellik".

When the plant is healthy, it can be put back in place.


To protect the exotic flower from serious problems associated with the appearance of the sticky layer, it is necessary to create optimal growth conditions for him and, in order to prevent, regularly examine the exotic:

  • the optimum room temperature in the summer is + 22 + 25 degrees, in the winter - + 16 + 18;
  • lighting should be diffused;
  • water the flower once a week; between waterings, the soil must dry completely;
  • fertilize 2 times a month with dressings with a high content of potassium and iron;
  • spray the flower with water daily.

Of course, it is easier to prevent the problem than to treat a sick orchid later. Now the appearance of sugar drops will not cause you to panic, since you know how to care for your favorite flower in order to avoid trouble, what you should pay attention to in order to notice the disease in time, and also what to do to cure your pet.
