One or several years is the best.
Grape seedlings can be bought at home for planting. Under normal circumstances, one-year seedlings and two-year seedlings can be bought. It is best to buy seedlings for more than one year but less than two years, which can go through two flower bud differentiation periods and bear fruit more easily in the third year. If the grape seedlings grow older, it is difficult to take root and survive after planting, and the number of fruits is less, so it is best to choose the grape seedlings that are young and not yet formed.
Second, how to plant
1, planting time: Grape seedlings are best planted in autumn, which can be delayed for a while, and begin to grow vigorously in spring.
2. Prepare the soil: Before planting the grape seedlings, choose the appropriate soil. Although it does not require high soil, it grows well in fertile and loose sandy soil.
3. Digging and pruning: Dig a large pit in the soil, put organic fertilizer and urea as base fertilizer at the bottom of the pit, and then cover it with a layer of soil. Prune the root system of grape seedlings, remove dead roots and rotten roots, leave healthy and developed roots, plant them in pits after disinfection, fill them with soil and compact them, and then pour water into them.
4. Maintenance management: After planting, cover the soil to keep warm, properly water it regularly to keep it moist, keep enough sunshine, and pay attention to pruning before spring.
