Matters needing attention in later maintenance of vase inserted with Lagerstroemia speciosa

1, water, potted Lagerstroemia indica at home also needs to receive almost the same sunshine as outside, even in high temperature environment, generally do not need shading. The cultivation position should be selected in the brick mud field far away from the wall as far as possible to prevent poor ventilation at the wall and raise the ambient temperature, which is unfavorable to the growth of Lagerstroemia indica. Watering in all seasons should follow the principle of "no watering, thoroughly watering". The specific watering amount should be determined according to the actual humidity of the basin soil. If the basin soil leaks, it should be replenished in time to increase the density of the basin soil. Fertilization and watering should be carried out in spring bud stage, summer bud stage and flowering stage, and the amount of water should be controlled from late autumn to early spring to keep the basin soil dry as much as possible.

2, cutting, specifically divided into softwood cutting and hardwood cutting. Generally, softwood cutting is carried out in rainy season, and hardwood cutting is carried out in spring, with good survival rate. When cutting, annual branches should be selected from vigorous mother plants, and the branches with a length of about 10- 15 cm should be pruned, and the cutting depth is about 8- 10 cm.

Generally, it can take root in about 20 days. Need proper shading and watering. The survival rate of branches is high, which can grow to about 60-80 cm in that year.

3. In the flowering period, Lagerstroemia indica has a strong ability to grow branches, with a large number of long branches. Therefore, it is necessary to cut off the residual flowers after flowering to promote the new growth of plants and make the next round of flowers germinate as soon as possible, thus prolonging the flowering period.

At the same time, we should also cut off long branches, diseased branches, overlapping branches and interspersed branches in time to prevent excessive consumption of nutrients.
