When to plant grape seedlings
Generally speaking, the best sowing period for grape seedlings is February or March in spring, and November in autumn.
How to plant grape seedlings
1. Grape seedling preparation
It is recommended to build in areas with good drainage and sandy loam soil.
2. Grape seedling pruning
(1) First-year pruning
When grape seedlings grow three to four true leaves and start to sprout leaves, one strong branch is left as the main grape vine for each seedling, while other sprouting new shoots and tender tendrils are removed. When the main vine reaches 1.2 meters, the first secondary branches within 20 centimeters from the base of the vine are rubbed off, and the first secondary branches above 20 centimeters are left with 1-2 leaves and pinched. When the main vine is 1.4-1.5 meters long, the top of the main vine is removed to cultivate the first secondary branch. When the main vine is 1.6-1.7 meters long, the third branch is removed, leaving one leaf at the top, and the rest of the third branches are removed, followed by normal winter pruning.
(2) Second-year pruning
When the new shoots are 15 centimeters long, the branches should be fixed, and the long, underdeveloped branches should be pruned back. It is advisable to leave 6 new shoots (with a bud spacing of about 15 centimeters) on each tree. When the inflorescences can be clearly distinguished in size, excess inflorescences should be retained, leaving 4-5 inflorescences per plant. If there are more inflorescences, it is best to leave one fruit cluster per fruiting branch. If there are fewer inflorescences, two spikes can be left for the fruiting branches. When the main vine of a two-year-old tree reaches 80 centimeters, it should be pinched flat. The fruiting branches should be left with 8-12 leaves 2-3 days before flowering or at the beginning of flowering, and the nutrient branches should be left with 10-12 leaves. The main vines pruned in winter should be slightly longer than 1 centimeter in diameter and pruned to 50-60 centimeters. The rest of the fruiting branches are pruned short.
(3) Grape seedling fertilizer and water management
In order to achieve the shaping purpose of the seedlings in the first year of planting and promote the maturation of the withered vines and plump buds, it is necessary to ensure sufficient fertilizer and water (G-Y). The principle should be to apply more, less, and shallowly. With irrigation, 4-5 applications can be made in a year.
