Can litchi beginning of spring be pruned?

Young fruit trees should be pruned all year round, but adult fruit trees should be pruned within 15 days after fruit picking, that is, they must be pruned well before attacking autumn shoots, so that autumn shoots can sprout in a suitable position. Pruning after fruit picking is a normal comprehensive pruning, such as retraction, renewal pruning and adjustment of crown structure.

In addition, the new buds can also be smeared in the bud stage, and it is best to smear too dense, too many and overlapping new buds after the young Ye Gang is unfolded. Premature smearing will weaken the growth of existing new buds. In addition, care should be taken not to prune the last branch after it matures, so as not to stimulate the occurrence of winter shoots. Not pruning during fruit development will promote vegetative growth, destroy the balance with reproductive growth, and be unfavorable to fruit setting.

Please note when trimming:

(1) should be from the inside to the outside of the crown, and from the big branches to the small branches, so as to avoid large local gaps on the periphery of the crown after cutting;

(2) pruning tools, twigs are cut with branches, big branches are serrated, and saws should be sharp;

(3) The cutting mouth should be smooth, and there should be no residual branches to avoid the invasion of pests and diseases after withering;

(4) If no fruit trees are hung in that year, they can be pruned early;

(5) After pruning, rotten fruits, dead branches, pruned branches and weeds on the ground should be removed, and centralized burning should be carried out to reduce the source of overwintering pests and diseases.

Maintenance of Litchi Tree after Picking

All we have to do is clean the garden. After litchi is completely picked, the fallen branches, fruits, bad fruits, dead leaves, dead branches, etc. will be cleaned up and treated centrally to avoid breeding pests and diseases and harming fruit trees.

(2) What needs to be done is pruning the branches. Litchi trees can't be pruned immediately after picking, and it will take about half a month to start. Because litchi trees are fragile after fruit picking, it is best to wait until the leaves turn green before pruning.

(3) What needs to be done is fertilization. After half a year's growth, the nutrients of litchi trees have almost been exhausted. Now, after picking the fruit, the plants need to be supplemented with nutrition in time. Fertilizing litchi trees in autumn can increase soil fertility, ensure the safety of fruit trees in winter, and prepare for germination in the next spring. Fertilization can be carried out 15 days after picking, so as to cultivate strong mother branches and promote flower bud differentiation.

(4) What needs to be done is the prevention of pests and diseases. Because the picked litchi trees have many wounds, dead branches and rotten fruits will breed pests and diseases, and summer and autumn are also the seasons with frequent pests and diseases. After cleaning and pruning, do not relax your vigilance and prevent common pests and diseases in advance.
