The planting time of summer black grapes is generally in spring and autumn. In spring, the seeds are sown before and after Qingming Chrysanthemum, and in autumn, the seeds are sown after all the leaves have fallen out.
Planting techniques of summer black grape
1, soil
Grapes are usually planted in relatively flat and open places, and summer black grapes are no exception. It is also necessary to ensure that the soil in the selected place has properties such as water permeability and air permeability.
2. Tie vines and prune them
When the new shoots are 50-60 cm long, the vines should be wound around the stems, the tendrils should be removed in time, and the young trees should keep enough nutrients to make them strong.
3. Fertilizer
The application of fertilizer after sowing is essential. Summer black itself has a great demand for fertilizer. In order to ensure the yield, we must make good use of organic fertilizer.
Management method of summer black grape
1 pruning
When 4-5 real leaves grow out of the new shoots, bud them. Proper pruning of the branches and leaves in the dense areas of the grape trellis can increase the transparency and ventilation. Before flowering, you can repeatedly pick the heart and tie the vines in time to make the trellis more tidy.
Step 2 water it
We should follow the principle of watering when it is dry and wet. When it is hot in summer, we should try our best to increase the number of watering, and when the temperature is low in winter, we should try our best to water less.
