How to cultivate Lagerstroemia indica

The common propagation methods of Lagerstroemia indica are sowing and cutting;

Lagerstroemia indica is sown in March-April and outdoors, and the seeds are evenly spread on the flat seedbed. Sprinkle about 2-3 capsules every 3-4cm. After sowing, cover with fine soil about 2 cm thick. After about 10~ 14 days, most seeds germinate and sprout, and soil moisture should be ensured after germination.

After the seedlings grow two pairs of true leaves, in order to ensure that the seedlings have enough growth space and nutrient area, we can choose to interplant the seedlings after the rain, so that the air between the seedlings is ventilated and the sunshine is sufficient. During the growing period, management should be strengthened, thin fertilizer should be applied 2-3 times in June-July, drought should be prevented in summer, and water should be watered frequently.

Cutting is carried out in July and August, when the new branches grow vigorously and have the most vitality, and the survival rate of cutting is high at this time. Select semi-lignified branches and cut them into cuttings about 10cm long, leaving 2-3 leaves at the top of the branches.

Cut about 8cm deep and water the seedlings. In order to keep moisture and keep warm, the seedbed was covered with a plastic film, and a sunshade net was built to shade the sun. Generally 15-20 days can take root. Uncover the film, keep the sunshade net, and water it properly during the growing period. Branches can reach 70cm in that year, and the survival rate is high.

Growth habit

Lagerstroemia speciosa likes warm and humid climate, light, a little shade tolerance, fat, especially the deep and fertile sandy loam. It is suitable for being born in a slightly humid place and is also resistant to drought and waterlogging. It is forbidden to plant in places with high groundwater level and low humidity. It is warm, but cold-resistant and has strong germination.

Lagerstroemia indica also has strong anti-pollution ability and strong resistance to sulfur dioxide, hydrogen fluoride and chlorine. Semi-shady, like to be born in fertile and humid soil, but also drought-tolerant, calcareous soil and acidic soil grow well.
