Red spider, one of the most common pests in Hong Yun, usually occurs in summer and mainly lives on the back of leaves or the base of leaf axils, and propagates very fast. Red spiders will prick and suck leaves, buds and flower and leaf juice, affecting the normal growth and development, not only affect the beauty, but also lead to the death of the whole plant.

Leaf tip yellowing is one of the common diseases in Hongyun. it is mainly due to improper watering, low air humidity and excessive fertilization, resulting in salt damage caused by too high salt in the plant soil. This is what we call physiological diseases, which we think are caused. In light cases, the leaves turn yellow, and in severe cases, the plants die directly.

Prevention and treatment: the disease is related to water, so our watering is very important, choosing the right water quality is more important. Try to choose water with less salt, water at home, and use it after exposure to the sun. Control the temperature and avoid the temperature angle to avoid frost damage.
