Ecological habits of Lagerstroemia speciosa

Strong adaptability, like light, slightly tolerant of shade. Like warm and humid climate, slightly cold-resistant. Not drought-tolerant and barren, suitable for fertile, deep and moist slightly acidic to slightly alkaline soil. The root system is developed. Strong germination ability and pruning resistance. Resistance to sulfur dioxide and hydrogen fluoride.

Multi-purpose sowing method: cut the ear of the fruit in winter, stroke the fruit, soak it in water, rub off the peel and dry it slightly, and mix the seeds into clean sand and store them in low temperature and humidity until sowing in early spring. The row spacing of drilling is 15 ~ 20cm, the sowing amount per mu is 7.5 ~ 10kg, and the covering soil thickness is1~1.5cm. Generally, the seedlings begin to emerge in mid-April, and the seedlings will be interplanted in time when they are full. The seedlings used for hedgerow planting should be cut off at 15 ~ 20 cm above the ground to promote the germination of lateral branches. If you are a street tree or courtyard greening, you should cultivate trees. After the seedlings are planted separately, they are cultivated for 2 ~ 3 years. When the height of seedlings is1.5 ~ 2m, they can be transplanted. Planting spacing should be 3×3 meters. If it is used as hedge planting, the spacing between plants should be 40 ~ 50 cm.

If cutting propagation is adopted, March in spring is the best season and the survival rate is high. Like light, slightly resistant to shade, warm and humid, suitable for slightly alkaline soil, strong anti-air pollution ability.
