How to Prune Grapevines
Grape pruning can be done in autumn and winter. You can use sharp scissors to cut off branches that are growing poorly or affected by diseases and pests, helping the plant save nutrients. After pruning the grapes, spray them with a carbendazim solution for sterilization, and you can also water some purified water to help the plant grow.
What to Do When Grape Branches Are Too Thin
When the grape branches are too thin, you can reduce the use of nitrogen fertilizer and increase the use of phosphorus and potassium fertilizers to slow down the plant's growth rate. You can also select grapes to inhibit branch growth and promote shoot growth. You can also provide grapes with mineral-rich water and keep the soil moist.
What to Do When Grape Leaves Turn Yellow
If the leaves of the grapevine turn yellow and wither, it might be due to excessive pesticide spraying, which burns the grape leaves and requires washing the blades with a large amount of water. It could also be due to too much water, in which case you need to reduce the frequency of watering. Alternatively, it might be because of high temperatures, in which case you need to take shading measures, spray to cool down, and promote strong growth of the grapes.
The above is a comprehensive explanation of how to prune grapevines, hoping it can help you.
