One of the most common pests that can affect plants is the spider mite.
Spider mites often infest roses, causing them to weaken, lose leaves, and become much more susceptible to various diseases.
Spider mites are so small that they are difficult to spot with the naked eye. Upon closer inspection, they resemble tiny, moving grains of sand.
Spider mites always live in large colonies—a hundred or more individuals. The main sign of their presence on a plant is a fine web on the underside of the leaf, with tiny parasites beneath it.
You can get rid of spider mites on roses with acaricides. The choice of product should always be based on the severity of the infestation.
