What should be paid attention to in the conservation of American red rocket Lagerstroemia indica and American red fireball Lagerstroemia indica?

1. Strengthen the light. Lagerstroemia indica likes sunshine, so it must be placed in a sunny place outdoors during the growing season.

2. Water it in time. Pot soil should be kept moist in spring and winter, and watered once every morning and evening in summer and autumn. In case of drought and high temperature, the daily watering frequency can be appropriately increased, and river water, well water, rainwater and tap water should be stored for 2 ~ 3 days.

3. Fertilize regularly. Too much fertilization on potted Lagerstroemia indica is easy to cause white branches and leaves. If the lack of fertilizer leads to thin branches and yellow leaves, the whole plant will grow weakly, with few or no flowers. Therefore, it is necessary to apply fertilizer regularly, apply more fertilizer in spring and summer peak season, and apply less fertilizer after autumn. There is no need to apply fertilizer when winter enters the dormant period. Don't fertilize at noon in rainy days and summer when the temperature is high. Fertilization concentration is applied every 10 day from beginning of spring to beginning of autumn, topdressing every half month after beginning of autumn, and fertilization is stopped after beginning of winter.

4. reasonable pruning. Lagerstroemia indica is resistant to pruning, with strong branching ability and large growth of new shoots. Therefore, after flowering, residual flowers should be cut off to prolong the flowering period, and long branches, overlapping branches, cross branches, radiation branches and diseased branches should be cut off at any time to avoid consuming nutrients.

5. Change pots in time. Potted Lagerstroemia indica is replaced every 2 to 3 years. Want to know more about conservation, you can search for green farmers in Jiangxi.
