White paint on poplar branches in spring will be harmful to trees, which will hinder the natural absorption of sunlight and water by poplar branches and affect the growth of trees. It is suggested that herbicide should be used instead of paint to control the growth of weeds and reduce the impact on trees.

Poplars in spring are evergreen shrubs or small trees, belonging to Salicaceae. Its leaves are wide and short, dark green, with obvious wedge shape, and white hairs on the back of the leaves.
