The grapevines bloom (from May to June) and bear fruit after 90 to 100 days (from August to September).

Spring in the northern and southern hemispheres is different. Spring in the northern hemisphere is generally from March to April, and spring in the southern hemisphere is generally from September to October. This is also the difference between European production areas and Australia, New Zealand and other production areas. .

After the dormancy of winter, the grapes sprout in spring and grow new vines and leaves. In May-June in the northern hemisphere and November-December in the southern hemisphere, petals begin to form and then bloom.

Growth habits

Temperature: The minimum temperature required for grape growth is about 12℃-15℃, and the minimum ground temperature is about 10℃-13℃ , the optimal temperature during the flowering period is about 20℃, and the optimal temperature during the fruit expansion period is 20℃-30℃. If the temperature difference between day and night is large, the coloring and sugar content will be better

Moisture: Grapes have high requirements for moisture, and strictly controlling the moisture in the soil is a prerequisite for growing good grapes. Grapes require more water in the early growth or vegetative growth stages. In the late growth or fruiting stages, the roots are weaker and require less water. Root damage should be avoided to avoid affecting quality.

Light: Grapes must have a certain intensity of light during normal growth. However, when the light is too strong, especially when the grapes enter the hard-core stage, sunburn is more likely to occur. At this time, bagging or plant removal can be used When leaving leaves, try to keep leaves that can cover the grape fruits.
