The Best Time for Grape Pruning
This article provides detailed knowledge about the best time for grape pruning for concerned netizens. The editor of the website will introduce the information to the readers.
The Best Time for Grape Pruning
The best time for grape pruning is during the autumn and winter each year, around November-December, which is the transition from autumn to winter, after the leaves have fallen. Grape pruning usually occurs in winter and summer. The pruning volume is highest in winter, and the specific timing depends on the situation. Different grapes have different pruning methods, influenced by factors such as tree strength and yield.
The Best Time for Grape Pruning
Grape pruning is generally carried out after the leaves have fallen, around November-December each year. During this period, the temperature is suitable, and the葡萄 plants can heal better after pruning.
Grapes are perennial vines that need to update their vines and balance the relationship between nutritional growth and reproductive growth. This enables the plants to grow strong and maintain robust fruiting capabilities, thereby extending the plant's lifespan and fruiting period, achieving high yield and quality.
In fact, grapes are suitable for pruning all year round, especially during dormancy. Seasonal pruning includes removing buds in spring, dealing with auxiliary shoots in summer, thinning weak and unnecessary branches in autumn, and solving the problem of enclosed canopy. Winter pruning has the highest volume, addressing vine renewal and adjusting tree strength and yield.
How to Master the Timing of Grapevine Pruning
Physiologically speaking, pruning should occur after the leaves fall and as temperatures drop, nutrients slowly flow from the upper part of the branches to the lower part, and grapes officially enter the overwintering state, which is the timing for winter pruning.
In reality, with such a vast north-south span in our country, the timing and speed of temperature drops vary by region, making it difficult to have a unified pruning time. In some places, pruning occurs two weeks after the leaves fall, while in others, it may be a month after.
How to Prune a Grapevine
In practice, in the north, it is necessary to cover the soil with mulch for insulation. Therefore, winter pruning and taking down the vines should be completed before mulching. If it's a warm winter, pruning may begin before the leaves have fallen.
In recent years, fully enclosed rain shelters have become popular, eliminating the need for mulching. Winter pruning usually takes place before the 19th day of the third lunar month or after the 19th day of the fourth lunar month. The most direct reason is that it's too cold during the 19th days of the third and fourth lunar months, making work difficult, so pruning is delayed until it's warmer.
Pruning methods should be adjusted based on the plant's growth and development stage. If the top of the grapevine is 1.2 centimeters thick, the pruning point should be at 1.5 meters. If the grapevine has poor growth, the pruning point can be reduced to 1.2 meters.
Weak葡萄 branches should be pruned heavily, as this promotes better plant growth. Additionally, pruning should remove diseased and yellowed branches to prevent unnecessary consumption of plant nutrients, improving fruit yield and quality.
