How to prune small walnut trees
After the seedlings of walnut trees are planted, they generally begin to blossom and bear fruit after two to three years of growth. After planting, the plants grow in soft soil and abundant water, and often grow particularly vigorously, and the branches are particularly strong. In order to promote the early flowering and fruiting of plants, besides applying enough phosphorus and potassium fertilizer and controlling water to a certain extent, reasonable pruning is also a very important management work. Because walnut tree is a kind of tree with bleeding period, unlike other fruit trees, it is not suitable for pruning in spring. To do a good job of pruning walnut plants, we must find the right pruning time.

The first period is early summer pruning. Because walnut trees, like vines, have bleeding periods, if you don't master the time node and operation method when pruning in spring, it will easily lead to the loss of juice from the branches of the tree after pruning, leading to the death of some branches or even the whole plant. Therefore, the best pruning time is from summer to around. Young trees dry when they grow to about 60 cm. Big trees can cut the vigorous branches long and short, make the branches grow more lateral branches, differentiate more flower buds, and create power for high yield.

The second stage is autumn, and the pruning time is from late August to mid-September. At this time, the newly grown branches are cut short. The preserved branches developed more fully in the last two months before freezing, and they will bear fruit when they germinate again in the next spring.

Walnut trees are also not suitable for pruning in winter, especially some walnut trees that begin to bear fruit. At the end of autumn, many buds have fully developed and have flower buds. If pruned in winter, these buds are likely to be cut off, resulting in fewer fruits in the next year. However, if it is the transverse branches, back branches, straight branches, diseased branches and dead branches that affect the light and ventilation, it should be cut off as soon as possible, and it can be removed in the summer growing season to avoid wasting the nutrients of the tree.
