When are grapes planted?
Are you curious about the month for planting grapes and some small green plant maintenance tips related to grape cultivation techniques and management? These tips will surely be helpful to you. Let's learn about them together!
Grapes can usually be planted in February or March. If planted late, the survival rate is lower. First, dig several trenches, add some organic fertilizer, and then place the grapevines. For later management, the trenches should be kept open to avoid water accumulation. Before planting grapes, we need to prune the seedlings first, cutting off the branches and the weak tips, retaining 2 to 3 strong main buds on the main branches to cultivate fruiting parent branches. Then, set up a trellis, which can be either a flat trellis or a vertical one. Continue pruning the growing branches, leaving only 7 to 8 leaves, cutting off the new branches, and retaining one leaf on the new branch tip for pinching, leaving nutrients for the fruit.
Disease and pest control: When the new branches grow to 20 centimeters to the early flowering stage, spray 200 times the semi-dose Bordeaux mixture 1 to 2 times to prevent gray mold. After flowering, spray Bordeaux mixture for protection. From late June, you can alternately use Bordeaux mixture and bactericides like carbendazim for control. Because July to August each year is the peak period for downy mildew, spray the medicine once every 10 days, for 2 to 3 consecutive times to prevent bacterial infection. Apply fruit-setting agents during flowering, generally after rainy days and sunny weather. Also, prevent the king Kong drill beetle from boring into the tender stems. Use specific medications based on the disease.
Fertilization and water management: The soil should not be too dry; grapevines prefer moist soil. Apply nitrogen and phosphorus fertilizers when newly planted, and switch to phosphorus and potassium fertilizers after the vines start growing. When the fruits are the size of peas, you can continue to apply compound fertilizers and wood ash to lay a good foundation for fruiting.
When the fruits are almost ripe, you can cover them with paper bags to prevent cracking due to dry weather or continuous rain, as well as protect against fruit-eating flies, bees, and birds.
In the late autumn and winter, we can thoroughly clean and prune the dead branches. Do not prune too late as the dripping of branches can also lead to nutrient loss. When pruning, retain 6 to 7 fruiting branches and cut off the branches above to effectively reduce the disease source. During the grape dormant period, spray 2 to 5 times with lime sulfur mixture to control black spot disease and powdery mildew.
