1, moisture?

Grapes have a high demand for water, and they need a lot of water in the early stage of growth and development. At the late stage of fruiting, because the root system is not weak, the water demand is greatly reduced, so you can't water too much. Otherwise, if the humidity is too high, the vines will grow wildly without fruit, which will easily lead to diseases such as black pox and gray mold. ?

2. Lighting?

Grapes also have certain requirements for light, because grapes are a plant. If you just want it to look like a shed, you just need to give enough water and a certain amount of base fertilizer. Because it is a vine, you should take it seriously if you want to eat grapes. Because the normal growth of grapes needs a certain intensity of sunshine, if the sunshine is insufficient, it will cause the grapes to fall out of flower or grow wildly without fruit. ?

3. Trim?

In order to prevent the grapes from growing wildly, some branches and leaves can be cut off appropriately, but not all. Keep the leaves that can cover the grapes, because the sun is too strong and the grapes will get sunburned. Therefore, we must pay attention to fertilization after cutting branches and leaves. ?

Extended data:

Grape transplanting is generally carried out from September to 65438+ 10. When the leaves of the grapes fall, choose to cut them. One-year-old robust branches, short internodes, 3 lateral buds, about 15~20 cm long, buried in sand for overwintering, and cuttage in March ~ April of the following year. ?

Grape root system is developed. In order to avoid potted plants taking root, first, use large pots; Second, turn the flowerpot once every two years to dilute the roots, and pay attention to prevent freezing damage in winter. ?

Planting time: the suitable period for planting grape seedlings, from defoliation dormancy to grape bleeding in the next year. Sowing in spring in most parts of northern China. When the soil temperature reaches 7~ 10℃ (usually in early April in Shandong), it can be planted in the field.
