Do you use pesticides to green the roadside area of holly? Don't you use pesticides? Does the video use pesticides?

Holly is easy to get powdery mildew without spraying pesticides. After infected with powdery mildew, the leaves are covered with white powdery substances, which affects the photosynthesis of leaves. If photosynthesis is blocked and nutrients cannot be produced, plants will grow poorly and their leaves will shrink and become slightly white and deformed. In severe cases, leaves and tender leaves will dry up and die, greatly reducing the greening and ornamental effects.

Holly is a beautiful tree with lush foliage and evergreen seasons. Most of them are planted in gardens for beautification. It is an excellent ornamental tree species, widely used in green walls, parks, highway central isolation belts and other places.
