Reasons for painting trees in winter

In winter, painting trees can effectively kill insects and bacteria. Insects in early winter like to be in the cracks of old trees, and white lime can kill insects. Pests are afraid of white, so pests in the soil won't climb trees painted with white lime. When it is cold in winter, the tree is brown, which will absorb a lot of heat, with large temperature difference and easy cracking. White lime can reflect light, so trees don't crack easily.

Why do trees whitewash in winter?

Painting white lime on trees in winter has the function of killing insects and killing bacteria, which can protect trees from being eroded by pests during dormancy. In early winter, insects like to be in the cracks of old trees, which will make the trees in jeopardy. Lime is painted to kill these pests.

Applying white lime to trees in winter can greatly reduce the harm of pests and diseases in spring and make trees more energetic in spring. Pests prefer dark and dirty places to white and clean places, so white lime water will keep pests away.

The whitewashing effect of lime water on trees in winter

Pests in the soil are afraid to climb the tree to eat when they see white lime water, which can ensure the safety of the tree. Small animals on the roadside also like to grind their teeth on trees. Lime can protect trees from too much damage.

Lime water can keep trees warm. The temperature is too low at night in winter, but in the daytime, the skin of the tree turns brown, which is easy to absorb light and the temperature will rise. If the temperature difference is too large, trees will crack easily. Because white ash has the function of reflecting light, the temperature difference becomes smaller and the tree is not easy to crack.
