How often do grape vines generally get eliminated?

Grapevines are generally considered to be eliminated when they are over 20 years old. However, not all varieties are eliminated at this time. The elimination criteria mainly depend on growth, health and economic benefits. Specifically, only grape vines that are too weak to grow new branches, are frequently infected with diseases and pests, and do not bear fruit or bloom need to be eliminated. There are also some varieties whose fruit quality improves the longer they are cultivated, and such varieties can continue to be cultivated. Therefore, the age at which grape vines are eliminated will vary depending on factors such as variety, growth conditions and economic benefits.

How to eliminate grape vines?

1. Elimination time

In actual operation, it is best to cull the grape vines during their dormant period to reduce the impact on new trees.

2. Elimination method

(1) Digging up the entire grape vine: This is a relatively thorough elimination method and is suitable for situations where the grape vine has incurable diseases or is severely aged. After digging, the surrounding land should be disinfected to avoid the spread of diseases and pests.

(2) Grafting and renewal: For grape vines that need to be eliminated, hard branch grafting and green branch grafting techniques can be used to replace the variety.

(3) Fertilization to restore vigor: If the grape vines are not dying and still have a certain ability to bear fruit, you can consider fertilizing to restore the tree vigor. When applying fertilizer, apply about 60-100 kilograms of farmyard manure per plant, and then apply about 1 kilogram of superphosphate.

(4) Elimination and utilization: The eliminated grape vines can be sorted into two parts: the woody part and the leaves, and other organic matter and microorganisms can be added, and then fermented into organic compost. Alternatively, some discarded grape trees have large branches and can also be used as raw materials for construction, such as building shelves.



To sum up, there is no fixed standard for the elimination of grape vines, but it is affected by many factors. Therefore, whether it needs to be eliminated should be determined based on the actual situation. In addition, attention should be paid to effectively handling obsolete grape vines and carrying out renewal and transformation to improve the economic benefits and fruit quality of the vineyard.
