What are the methods and precautions for growing grapes?

Grape cultivation methods

Grape is a vine plant of the Vitaceae family and the genus Vitis. The methods of grape propagation include: cutting propagation, layering propagation, and grafting propagation.

The minimum temperature required for grape growth is about 12 to 15 degrees. It is best to provide a temperature of about 20 degrees during the flowering period. The temperature during the fruit expansion period needs to be between 20-30 degrees. If the temperature difference between day and night is large, the coloring and sugar content will be better.

During the growth period of grapes, the application of nitrogen fertilizer should be controlled, and attention should be paid to applying more phosphorus fertilizer and high-carbon organic matter. It has high requirements for water and needs to keep the soil slightly moist. Grapes must have a certain intensity of light during normal growth, but shade is needed in summer. It is best to plant them in loam and fine sandy loam.

Watering method

Grapes have high requirements for water. They need to be replenished with water in time in the early growth stage or the vegetative growth period. They need less water in the late growth stage or the fruiting period. Watering should be controlled. Grapes should avoid rain and dew. Drainage measures need to be taken during the rainy season.

Fertilization method

Grape nutrition can be supplemented in three ways: basal fertilizer, topdressing, and foliar fertilization. Basal fertilizer can be applied during hibernation or after harvesting, chemical fertilizer can be sprinkled when watering after flowering, and lime can be applied to soils with a pH value below 6.0.

Pruning methods

Generally, after the grapes sprout, they can be pruned, leaving the useful buds and cutting off the useless, too weak, unhealthy, and those that sprout too late. When multiple buds sprout from one bud point, leave the main bud and remove the rest.

Grape cultivation precautions

When watering grapes, pay attention to the water temperature, which should be close to the temperature of the potting soil. In summer, water them before 10 am and after 4 pm, avoiding the hot noon. Water them every 2-3 days in early spring and every day in summer. As the temperature gradually drops in autumn, the number of waterings gradually decreases.
