In winter in Los Angeles, how should I prune my Wei Zihua?

After entering the defoliation dormancy period (about 65438+1mid-October) to the late February of the following year, the author strongly suggests adopting the policy of "ignoring". At this time, the plants have fallen leaves, and most nutrients flow back to the trunk. The stimulation of pruning does not help growth, but creates many unnecessary wounds. If there is a cold current at this time, there will be a crisis of frostbite. However, in early March, the dormancy period of Lagerstroemia indica will end, which is the best time for pruning. At this time, branches with inappropriate spatial arrangement should be thinned, while the remaining branches should be lightly to moderately pruned (based on the principle of cutting off no more than half of the nodes), depending on the spatial arrangement. If it is potted Osmunda japonica, this is also the best time to change pots.
