Excuse me, what is the name of this flower and how to raise it?

Cultivation method of Osmunda japonica:

1, soil

Lagerstroemia indica has strong environmental adaptability and can be applied to general cultivated soil. If conditions permit, you can choose deep and fertile sandy soil for cultivation, which is most conducive to the growth of Lagerstroemia indica.

water

Lagerstroemia indica can resist drought and avoid waterlogging. You can water it once a year before germination in spring, freeze it once after defoliation in autumn, and pay attention to "no watering" at other times. Water in spring drought 1-3 times; Drainage should be done well in rainy season to avoid root rot caused by accumulated water; There is generally no need to water in autumn.

3. Lighting equipment

The growth of Lagerstroemia indica needs sufficient light, otherwise there will be few or no flowers in flowering period, and what is more serious is that the whole plant will grow weak.

4. Temperature

The grown Lagerstroemia indica plants have strong cold resistance, but it is necessary to do a good job in cold protection and heat preservation of seedlings. After more than three years of cultivation, the heat preservation can be stopped.

5, fertilization

It is similar to watering time. Fertilize once before germination in spring and once after defoliation in autumn. It can be smeared with human excrement or sesame sauce residue, which can promote the growth of plants in the coming year to be more vigorous and the flowering period to be more lush and bright.

prune

Because the inflorescence of Lagerstroemia indica is planted at the top of the new branches in that year, it is necessary to pay attention to the re-cutting and retraction of the annual branches, which is beneficial to concentrate nutrition and make the branches grow stronger. Long branches, drooping branches, pests and diseases, dead branches, slender branches, endogenous branches, etc. should be cut off, and the side branches at the lower end of the plant trunk should be cut off in time during the young tree period to reduce the consumption of nutrients and ensure the formation of a good crown on the upper part of the plant trunk.

7. Pests

Lagerstroemia indica is easily infected by pests such as scale insects, yellow thorn moths and giant salamander moths, and measures such as spraying chemicals should be taken in time to prevent and control it.
