Will crape myrtle have yellow leaves in September?

Yellow leaves. The new branches of Osmunda japonica bloom, and the germination ability of Osmunda japonica is very long. The more pruning, the more germination. Pruning Osmunda japonica is mainly divided into winter pruning and post-flowering pruning.

Pruning time in winter should not be too early. Osmunda japonica is a deciduous plant. After autumn, the leaves will gradually dry up and fall off until winter.

Osmunda japonica needs to be pruned as a whole in winter, and the pruning time should not be too early. Should wait until the ambient temperature is lower than 0℃ before pruning. At this time, all the nutrients in the branches basically returned to the trunk and roots, and the branches were pruned, so there was no great loss of nutrients to the plants.

Precautions:

Heavy pruning should be used to trim Osmunda japonica in winter. Osmunda japonica has strong germination ability and can be directly pruned into polished rods. In the second year, a large number of branches will sprout from the top of the trunk, and these branches can basically bloom under other light and nutrient conditions.

At the same time, after the whole inflorescence is pruned, other buds of this branch will sprout new branches, and these branches will continue to bloom, and the subsequent flowers will become bigger and bigger, and the flowering period will be greatly extended. Of course, this needs to be based on adequate nutrition of plants.
