First, soil consolidation The author believes that: in order to think of crape myrtle blossoming, we must change the soil. Lagerstroemia root system developed, due to rapid growth, consumption of large amounts of water and fertilizer, the soil is easy to compact, resulting in weak water and fertilizer retention, poor air permeability, which is the main reason for the crape myrtle flowering is not ideal. If you can change the basin soil every year is best, but at least compared to other trees bonsai soil change. Second, fertilizer and water shortage Regardless of the use of trees in gardens or bonsai production, we must pay attention to Ziwei's fertilizer and water management. In the crape myrtle growing season, it is better to apply light feces (urine) water or decomposed oil cake water once a week. In the hot season, it is appropriate to pour water every morning and evening. If crape myrtle severely loses water, it will cause fallen leaves, dead shoots and even the death of the whole plant. If the young shoots of Lagerstroemia are found to be pulling, they must be immediately replenished. Even in the middle age of the scorching sun, watering the crape myrtle will not have any adverse effects on the plants. The lack of fertilizer water on the flowering of Lagerstroemia can not be ignored. Third, improper pruning Lagerstroemia is blooming on the new branches each year. If it is allowed to grow naturally, it will not be trimmed at all. It will greatly affect the quality of crape myrtle blossom. Conversely, pruning will also cause the crape myrtle to bloom less or not at all. Some people mistakenly understand that the method of shortening crape myrtle blossoms is blindly cutting and cutting. Taking Chongqing, the author's location, as an example, I think that in addition to the annual heavy shearing in winter, we will carry out a heavy cutting of 2-3 branches each year from May to early June. Except for extra branches.) It is very beneficial to prolong the flowering period by cutting flowers in time. It is worth noting that the branches should not be stored too short when cutting the flowers, and the residual flowers will be cut off. The effect will be better. Fourth, insufficient light Lagerstroemia sex hi light, in the absence of light will appear branches lengthy, sparse internodes, sparse flower buds, dark and other phenomena. The author suggested that the crape myrtle be placed in the place where it can be exposed to sunlight for the longest time. V. Serious pests In the middle and late June and early July, especially in the rainy season, the crape myrtle is prone to roll leafworms in the early stages. Leaf curlers often damage the shoots of crape myrtle, which leads to severe loss of buds or the formation of flower buds, which seriously affects the quality and quantity of flowering, which is unsightly. To deal with roll leafworm should be combined with prevention and control. It is recommended to spray with omethoate, enemies, and the like. At the same time, the harm of scale insects should not be ignored. It is better to spray the scale insecticide with lime sulfur. When using lime sulfur, it is best to add a small amount of detergent to use. Also to prevent the emergence of Ziwei sooty.
