When is the litchi tree suitable for pruning?
Litchi trees can be pruned all the year round, but before attacking autumn shoots, pruning work must be done well, such as retracting, renewing pruning and adjusting crown structure.
How to prune the branches and leaves of litchi trees
Pruning in full fruit period: Litchi should be pruned, retracted and thinned in full fruit period. After the fruits are picked in summer and autumn, the mother branches that bear fruit in that year are generally cut short.
Pruning of old trees: The rejuvenation of old trees is mainly to regenerate branches and trunks through retraction pruning. After strengthening management, the tree recovered and achieved the goal of high yield.
Treatment of over-dense trees: Over-dense trees are mainly aimed at cross-shading caused by improper pruning, declining tree vigor, breeding of pests and diseases, and declining output year by year.
Pruning skills of litchi trees
Pruning grows fast: young litchi trees are shaped with round heads of main branches within 2~3 days after planting, and branches are inhibited by cutting short, removing cores and draining before new shoots germinate. It is mainly to cut off dense branches, bent branches and weak branches, so that nutrients can be effectively utilized and the crown of trees can be expanded.
There are many results of pruning: litchi trees can increase the number of fruits by cutting off fruit stems and dead branches, non-ideal branches and late autumn branches damaged after high temperature in summer, and retaining strong branches and transverse branches.
Matters needing attention in pruning litchi trees
Litchi trees should be pruned from the inside out, from big to small. Branches should be trimmed with branches, and big branches should be serrated. When the fruit trees were not hung, they could be pruned earlier.
