Maintenance after pruning:

1, disinfection and sterilization

Pruned apple trees should be sprayed with potassium permanganate disinfectant or coated with a layer of plant ash to avoid apple tree wound infection. If the incision is too large, it is necessary to wrap the incision with a cloth to allow the apple tree to grow normally.

2. Humidity conditions

After pruning, the flat fruit trees need to be replenished with water. Sprinkle some water on the roots of plants with a kettle to keep the soil moist, but don't drop water on the wounds of apple trees, or the trunk will turn black and rot.
