What are the cultivation methods and precautions for grapes
During the growth of grapes, it is necessary to control the application of nitrogenous fertilizer and pay attention to applying more phosphorus fertilizer and high-carbon organic matter. Grapes require a higher amount of water, needing to maintain slightly moist soil. Grapes must have a certain intensity of light during normal growth, but shading is needed during strong summer sunlight. It is best to plant them in loamy soil or fine sandy loam soil, with the fruit expansion period requiring temperatures between 20-30 degrees Celsius.
Method of grape cultivation
Grapes belong to the Vitaceae family and are a type of vine plant. The propagation methods of grapes include cutting propagation, layering propagation, and grafting propagation.
The minimum temperature required for grape growth is about 12 to 15 degrees Celsius, with the flowering period preferably at around 20 degrees Celsius. The fruit expansion period requires temperatures between 20-30 degrees Celsius. Larger day-night temperature differences result in better coloring and sugar content.

Irrigation method
Grapes require a higher amount of water, especially during the early growth or vegetative period when it is necessary to supplement water promptly. In the later growth or fruiting period, less water is needed, and irrigation should be controlled. Grapes dislike rain and dew, so drainage measures must be taken during the rainy season.
Fertilization method
Grapes can supplement nutrients through three methods: base fertilizer, topdressing, and foliar application. Base fertilizer can be applied during dormancy or after harvest. Chemical fertilizers can be scattered during watering after flowering, and lime can be applied to soils with a pH value below 6.0.
Pruning method
Generally, pruning can be done after the grape sprouts, leaving useful sprouts and cutting off the unnecessary, weak, unhealthy, or late-emerging ones. When multiple sprouts emerge from the same bud point, the main bud is left and the rest are removed.
Precautions for grape cultivation
When watering grapes, attention should be paid to the water temperature, which is best to be close to the potting soil temperature. In summer, water early in the morning before 10 am or after 4 pm in the afternoon, avoiding the hot midday. Water every 2-3 days in early spring, daily in summer, and reduce the frequency as the temperature drops in autumn.
