Landing rules
Seedlings take root best when they are 2-3 years old. Planting is usually done before the buds fully open or after the leaves fall, following the following pattern:
- Dig a hole measuring 40x40x50.
- Lay a drainage layer of up to 10 cm of broken brick or gravel on the bottom.
- Pour 10-15 cm of fertile soil on top.
- Straighten the roots of the seedling and bury it to the root collar.

Planting a seedling with closed roots is permissible at any time from the beginning to the end of the growing season. During the hot season, he needs to create temporary shelter from the sun.
Watering and fertilizing

In warm regions, you can postpone pruning to early spring. Gardeners wait for sprout buds to appear and leave 3-4 of them on each shoot. Annual pruning includes the sanitary part: cutting out diseased and crooked branches.
Preparing for winter

Diseases and pests
