one spider mite
If you notice that cobwebs have begun to appear on the leaves, even in small quantities, do not write it off as an ordinary spider or dust. Most likely, this is a spider mite — a tiny insect that could bring into the room from an open window or from a recently purchased flower. Most often they appear in the summer — they need warmth and lack of dampness.
In addition to an unpleasant web, they are dangerous because they feed on the juice of a plant, slowly killing it. Therefore, they must be disposed of as soon as you notice their presence.
In gardening stores you can find special preparations (for example, Fitoverm, Akarin) that destroy not only spider mites, but also other harmful insects — acaricides and insectoacaricides. They can be chemical or biological, depending on the composition, but they work in much the same way.

3 powdery mildew
Another common problem that you may encounter when planting houseplants is the appearance of white bloom. These are no longer parasitic insects, but a fungus that could occur if you watered the plant too much or the flower suffered from temperature changes.
If the plaque has just appeared, cut off the damaged leaves, treat the cut and all unaffected leaves with an antibacterial spray for plants. If there is a lot of plaque, go to the store for a fungicide solution. As a rule, it should be applied 2-3 times with an interval of 10 days.

If you know that you have not violated the watering regime and there are no reasons for such drying, treat the flower for fungus.
The affected leaves must be removed, the watering regime, temperature and humidity in the room should be adjusted. Since the fungus appears in a small amount immediately on the whole plant, it will be necessary to treat the trunk, branches and leaves with a solution of fungicides.
