Cultivation techniques of Lagerstroemia indica

It can be propagated by sowing and cutting. A large number of healthy and tidy seedlings can be obtained by sowing. Seeds are usually harvested in late autumn and sown in February-March of the following year. The seedbed can be covered with film, and the film can be removed after the real leaves grow to prevent the seedlings from being infected with stem rot due to excessive humidity. If the sun is too strong during the day, the seedlings should be properly shaded. After the cotyledons grow, you can spray potassium dihydrogen phosphate once every half month. Remember not to be too thick. It is advisable to dilute 1500 times solution to prevent young leaves from being burned. It can be planted in a month.

Cutting is usually carried out from March to April. During this period, the temperature is neither too high nor too low, and the branches are nutritious and easy to survive. One-year-old semi-woody branches should be selected, and the branches without sprouting lateral buds are suitable, and the cutting length is 10 cm. The bed insertion requires good air permeability and no water accumulation. After the cuttings are inserted, they should be sprayed in time during the day and properly shaded when the temperature is high. It takes about a month for cuttings to take root, and the survival rate is generally above 90%. When planting, you can't pull out the seedlings directly, you should loosen the soil properly, otherwise the roots will be brittle and easy to break. Planting management: seedlings are generally planted in calcareous soil with good drainage, and potted management can also be used. After survival, dilute manure can be applied once a week, and organic fertilizers such as cake fertilizer can be added in peak season, and chemical fertilizers should be used as little as possible. When plants grow up, they should be picked in time to facilitate the sprouting of lateral branches and make them plump. From June to July, almost all plants will bud, but flowering will have an impact on the growth of seedlings, so it is necessary to wipe the buds in time and store nutrients to facilitate their further germination and growth. By the second year, this plant is not only full in shape, but also colorful in flowers.
