Spider mite: how to treat a plant when a spider web appears?
Spider mites most often damage young seedlings. It feels good in dry air. And if the summer turned out to be especially hot, then the tick will easily damage even adult marigolds. Take action in time, otherwise the plant will dry out and soon die. Signs of the appearance of a tick are a whitish shade on the leaves. The web must be cleaned by hand, so as not to injure the delicate leaves.

The resulting infusion is treated with the affected marigolds. Soon the spider mite will retreat, because it cannot stand the smell of tobacco.
How to deal with aphids?
One of the worst pests for marigolds is aphids. She is able to destroy the plant. The parasite settles on all parts of this garden culture - from leaves to roots. And it literally sucks in the juice from the cells and secretes poison. As a result, the leaves deteriorate and die off. Their complete deformation occurs, the tops of the plant are bent.
If, in addition to the above signs, you notice sticky sap on the leaves, this is the main sign of aphids.
