Walnut should prune its overgrown branches in spring, do a good job of coring in summer, and cut off all overlapping, forked and drooping branches. At the same time, it is necessary to cut the crown into a fan shape, cut off the branches that have blossomed and borne fruit in autumn, and cut off all withered, pests and delicate branches in winter to reduce the consumption of nutrients.

Pruning time of walnut

Walnut can be pruned many times a year, and the best pruning time is before falling leaves in autumn and after germination in spring. Because the leaves of the walnut tree have sprouted in the long summer solar term and the fruits of the walnut tree have been basically picked in the Bailu solar term, these two time points are suitable for pruning the walnut tree.

Pruning walnuts in time can accelerate the formation of branches, increase the number of branches, thus improving the fruiting ability, making fruit trees grow and bear fruit correctly, and achieving the requirements of early, stable and high quality.

Pruning method of walnut

1, spring pruning

When pruning walnut trees in spring, it is mainly to prune the branches on the trunk, cut off the branches and apply carbendazim for sterilization, so as to promote the growth and development of the lateral branches of the plants and facilitate the flowering and fruiting of the plants. At this time, sufficient light should be given to accelerate wound healing and inhibit excessive growth of plants.

2, summer pruning

When pruning walnut trees in summer, the branches in dense areas are mainly cored to improve the ventilation and transparency of the plants. You can also cut off all the overlapping, forked and drooping branches, and at the same time trim the crown and trim the crown into a fan shape.

3, autumn pruning

When pruning walnut trees in autumn, it is mainly to cut off the branches that have blossomed and borne fruit, and cultivate the healthy branches that have not borne fruit as the new trunk, which is conducive to better flowering in the next year, enhancing the growth trend of plants and promoting the differentiation of mixed buds.

4, winter pruning

When pruning walnut trees in winter, all withered, insect pests and delicate branches growing on the plants should be cut off. After applying carbendazim, cover the wound with plastic film in time to prevent water loss from plants. It is also necessary to loosen the soil once to avoid excessive water accumulation at the bottom of the soil, which will lead to root rot of plants.
