It is an excellent garden ornamental flower and one of the good varieties of stump bonsai.

Third, how to plant Lagerstroemia indica

1, planting

(1) ground planting: planting from June after defoliation 1 1 to March of the following year. When planting, leave the trunk 100~ 120 cm high and cut off the upper part. After the new spring bamboo shoots grow, choose 3~4 main branches with suitable angles and let them blossom.

(2) Potting: It is a good way to cultivate potted plants quickly by using seedlings from old branches transplanted alive in that year. Because the branches of Lagerstroemia indica are soft, potted Lagerstroemia indica can be properly climbed and bound. Generally speaking, when the growth of spring shoots stops and the branches are semi-lignified, they are coiled and shaped, and drawn into bonsai in various postures with thin brown ropes.

2. Fertilization and pest control

Generally, crape myrtle management is relatively extensive. In early March, spraying fertilizer was applied, and N, P and K were applied in combination: from late May to early June, P and K fertilizer 1 time was applied to strengthen branches and promote flowers, and flowering fertilizer 1 time was applied in late July and early September respectively, and the fertilizers were cake fertilizer and water. So that flowers can bloom. If diseases are found, Bordeaux solution or 600 times carbendazim solution should be used for prevention and control.

prune

The flowers of Lagerstroemia indica grew on the sprouting spring shoots at that time, with strong germination and irregular crown, which needed pruning.

(1) Winter pruning: In order to ensure normal flowering and form large inflorescences, winter pruning is very important. When planting on the ground, the branches born at that time should be cut off at the height of the main branch (fist) to make the robust branches bloom in the next year. First of all, all budding branches, diseased branches and overlapping branches in potted plants should be cut off. In order to beautify the shape, the branches should be cut off at the position 1 cm above the full terminal buds of other branches, generally leaving only about 5 cm.

(2) Pruning after flowering: After flowering in summer, cut off some residual flowers to prevent them from bearing seeds, so as to reduce nutrient loss and promote new branches and flowering. Pruning in growing season should not prune new branches or short nodes sprouting in spring. Otherwise, it is easy to cause only long branches and no flowers.
