The role of pruning potted crape myrtle

The flowers of potted crape myrtle mainly bloom on the branches of the current year, so if we make full use of this characteristic and prune the crape myrtle multiple times under proper maintenance and management and sufficient nutrients, we can achieve the purpose of multiple blooming. This method is also called "rotational pruning."

Pruning time for potted crape myrtle

Generally speaking, it is more appropriate to prune crape myrtle in winter. When pruning, you can prune all the branches with more complex growth or diseased and dead branches, and ensure that the crown of the plant is relatively neat.

How many times should potted crape myrtle be pruned?

Potted crape myrtle can be pruned six times. Heavy pruning should be done in winter according to the needs of shaping. In early April every year, when the new shoots grow to more than 10 cm, half of them can be cut back, and those branches that affect the appearance can also be cut off.

In June, flower buds are slowly forming, and one of the double branches can be cut off. Around July, the branches that have already withered should be cut off in time. In early August, after the flowers have withered, they should also be cut off in time. In late August, the third flowering has arrived, and the branches that have withered should be cut off again.

Propagation of potted crape myrtle by cuttings

Potted crape myrtle is suitable for pruning and propagation before spring budding. Choose strong crape myrtle branches with a length of 15-20 cm, then insert them into a cultivation medium mixed with garden soil, peat and river sand in equal proportions, and water them once.

How to prune potted crape myrtle

1. Winter pruning: After the crape myrtle completely enters the dormant period, it can be heavily pruned. Dead branches, diseased branches, and weak branches can be pruned away to reduce nutrient consumption. For trees with better natural conditions, the one-year-old branches can be cut close to the main trunk, and only 2-3 thick branches need to be retained as the mother of new branches the following year.

2. Spring pruning: Crape myrtle has a very strong germination ability and will sprout more branches and buds in spring. In order to ensure the beautiful shape of the tree and reduce the occurrence of diseases and pests, bud pruning must be carried out. Bud pruning must be done at least three times, with a cycle of 7-10 days.

3. Summer and autumn pruning: Summer and autumn pruning can effectively prolong the flowering period. It is usually carried out about 10 days before autumn. The flower branches of the current year are cut short, leaving only 2 to 3 buds at the base of the flower branches to allow new flowers to grow. After pruning, ensure that the plant grows in a well-ventilated and sunny environment.

Precautions for pruning potted crape myrtle
