White time

Tree trunks can be whitewashed from late November to mid-February of the following year. During this period, the temperature is low, the cold air sinks, and the trunks are most vulnerable to freezing damage. Some pests and bacteria live through the winter in the cracks of the trunk epidermis. Whitening the trunk at this time will do more with less.

Whitened area

The main trunk and main branches of the ginkgo tree should be painted. The height of the main trunk is about 1.5 meters above the ground. Large trees with incomplete crowns, diseased trees, and the south of the trunk should be painted white. Ordinary branches and branches of the year should not be painted white to avoid burning the cortex.

Tuqianqingyuan

It is emphasized again here that the garden must be cleared before whitening. After winter pruning, the litter, pest branches, pruned branches, and scraped old peels are cleaned to the garden. Outside, buried deep or burned. Then whiten it.

Go with it

The whitening agent should be used as soon as it is prepared, and used as soon as possible after it is prepared, not for a long time. In order to prevent waste, the dosage can be determined based on experience, or make a little less first, and then make less.

Apply meticulously

Choose sunny weather, dip a brush or straw into the whitening agent, and smear the fruit trees evenly and carefully. Don't be careless and quick to avoid affecting the whitening effect.
