It's time to paint the tree white. How can I paint the tree white?

A layer of white paint on the tree is usually called whitewash, which is a mixture of stone and sulfur (not pure lime). Painting is done before winter.

Paint to prevent freezing and damage the wintering place of pests and diseases. Most mites and some scale insects, such as Lagerstroemia indica and persimmon scales, overwinter in cracks in bark. Pear net stinkbug is in the rhizosphere bark of the host tree. Whitening trees in winter can prevent freezing and kill insects. Generally, the painting height is 1, 5m above the ground. Preparation of common whitening agent: 5 kg of quicklime, 0.5 kg of stone sulfur mixture stock solution or sulfur powder, 0.5 kg of salt, 0. 1 kg of animal oil or tung oil, and 20 kg of water. Firstly, quicklime and salt are mixed into liquid, then oil is added and mixed with lime-sulfur mixture evenly.

In winter, most pests and diseases have entered the hibernation period. At this time, painting the trunk can greatly reduce the harm of pests and diseases in spring and get twice the result with half the effort.
