What is the effect of brushing lime water on trees in winter?

1. It has the effect of sterilization and insecticide; it can reduce the harm caused by pests and diseases in spring

The most important function of lime water is to kill insects and bacteria and protect trees from being eaten and harmed by pests and bacteria during their dormant period. In early winter, insects like to lay eggs in the cracks of old bark, which puts the trees in danger. Applying lime water can kill these pests and make their "overwintering" plans fail, thereby greatly reducing the damage caused by pests and diseases in the spring and allowing the trees to be full of vitality and spring.

2. Prevent pests from climbing trees; prevent bark from being bitten by animals

Pests like dark, dirty places and don't like to stay in white and clean places. Therefore, the white color of lime water will make them "daunted", and the pests in the soil will not dare to climb up the trees to harm and eat the trees, thus ensuring the safety of the trees. The small animals on the roadside also like to grind their teeth and play on the trees, and this layer of lime can also play a certain protective role, so that the trees will not suffer too much damage.

3. Prevent frost damage and keep warm; reduce the large temperature difference between day and night

You know, winter is very cold, and we humans all wear thick down jackets to keep warm. Then the lime water is equivalent to the "down jacket" for trees. After the lime water dries, it can keep the trees warm and allow them to spend the winter safely. The temperature is very low at night in winter, but during the day, due to the rising temperature, the bark of the trees is dark brown and easily absorbs light and heat, so the temperature will rise quickly. Such a large temperature difference will make trees vulnerable to freezing and cracking. Apply lime water, because it is white, it can reflect 40% to 70% of the sunlight, reducing the temperature difference between day and night of the tree and preventing it from cracking easily.

Finally, in agriculture, lime can also be mixed with copper sulfate to produce the famous pesticide "Bodol solution", which is a powerful fungicide that is very useful and can protect plants.
