Sister Zhi: Can I fix it like this? Leaves are always falling recently.
Memories of late summer: of course, you can trim it like this to make the height look roughly the same. This pruning is equivalent to topping. The effect of pruning is that each branch will grow new branches and leaves, and the crown will flourish again after a period of growth.
The reason for complete defoliation is that the original soil is too hard and airtight. After watering, polarization is caused, either the soil is dry and hardened, or the soil is dry and accumulated water for a long time after watering. In either case, it will affect the root system. Either the temperature difference between day and night has changed, and it is hot during the day and cold at night (the temperature difference between day and night here is 10 degrees, not in your place). Either there are pests and diseases. Find the reason and judge for yourself.
The conversation is over!
When is the best pruning time for rich trees?
The best time should be from early May to mid-May, but it will be different according to the regional climate. Because of the mild climate in the Yangtze River basin, April can be chosen. The temperature in this period is very suitable for the growth of plants, and it is also conducive to the germination of new buds and the growth of new branches. Note that in March-April before pruning, it is necessary to adjust to a suitable temperature for management, so that nutrients can be accumulated and can be recovered quickly after pruning.
How to maintain the rich tree after pruning?
Pruned rich trees should be moved to a cool and ventilated place for maintenance, and some bactericidal spirit should be sprayed on their wounds for disinfection, so as to avoid wound infection leading to suppuration and affecting the normal growth of plants.
1, watering: reduce or even temporarily stop watering. Because the transpiration of plants will be weakened after the branches and leaves become less, the water needed will also be less.
2. Fertilization: A little fertilizer can be applied before the new branches germinate, mainly nitrogen fertilizer. After about a month, new branches will grow one after another, and at this time they can be moved to the sun for normal maintenance.
