What to Do If Grapes Grow Too Slowly
This article provides information on what to do if grapes grow too slowly and detailed methods to promote grape growth, as follows:
When farmers grow grapes, they naturally want them to grow quickly and well. Actually, achieving this is quite simple; it just requires careful maintenance. Below are six points on how to make grapes grow faster: early planting, bud removal and shoot selection, reasonable fertilization, short root planting, film mulching, and pest and disease control.
1. Early Planting
The choice of planting time determines the growth of grapes. Because after planting, grapes have a period of seedling establishment, which should not conflict with the germination period. If grapes can be made to sprout new roots early and adapt to the new environment, they will grow quickly in the spring. Generally, planting in autumn is better than in winter, winter is better than spring, and early spring is better than late spring.
2. Bud Removal and Shoot Selection
Bud removal in grapes is usually carried out twice a year, once during the germination period and the second time 10-15 days after the first. At this time, strong large buds should be left, weak branches, diseased branches, and branches in poor condition should be removed, and dense growth areas should be thinned. When new shoots grow to about 10-20 centimeters, branches with inflorescences can be selected, making sure that the branches left are basically uniform, which can concentrate nutrients and promote grape growth.
3. Reasonable Fertilization
Before planting, sufficient base fertilizer should be applied to promote grape growth. During later growth, timely topdressing is also necessary. When the new shoots of the grapevines have grown to 4-7 leaves, topdressing should be done promptly, usually using fast-acting nitrogen fertilizer, and combining it with a 0.4% concentration of urea solution, applying 1.25-1.75 kilograms of water per plant every 8-12 days. After August, the topdressing fertilizer should be changed to a 0.4% concentration of potassium sulfate compound fertilizer mixed with water solution, applying 1.25-1.75 kilograms of water per plant every 12-15 days.
4. Short Root Planting
Because the root system of grape seedlings is well-developed, long roots should be cut to about 13-15 centimeters during planting, which helps the growth of the grape root system and can promote nutrient absorption and transmission, speeding up the growth of branches and buds.
5. Film Mulching
Because the temperature in early spring is relatively low, low temperatures can inhibit grape growth, so farmers can cover the seedling trays with a layer of black plastic film to ensure that soil moisture does not evaporate, keep the temperature, exclude light, and prevent weeds, which is beneficial for grape growth.
6. Pest and Disease Control
When growing grapes, the invasion of pests and diseases is most feared. Pest and disease control is mainly preventive, so generally, a broad-spectrum fungicide can be sprayed before and after rain to suppress the occurrence of pests and diseases. Microelements can also be added to the pesticide to supplement the nutrients of the grapevines.
