No timely pruning: In the growth period of Lagerstroemia indica, if the branches are not properly pruned, not only will the overall appearance be affected, but also the nutrients in the potting soil will be excessively consumed, so that the flower buds can not sprout.
High alkali content in the soil: Lagerstroemia indica is suitable for growing in acidic soil. If the alkali content in the soil is high, exceeding one percent of zero, and the PH value exceeds 7.5, then the normal development and later flowering of Lagerstroemia indica will be affected.
Uncomfortable temperature: The temperature in the original place of Lagerstroemia indica is relatively high, so when maintaining Lagerstroemia indica, it is necessary to keep the temperature of its growth environment suitable, otherwise it will easily lead to insufficient transpiration, making it impossible to produce specific nutrients.Eventually, when it blooms, it is difficult to bloom because of insufficient nutrient storage.
Improper fertilization: If too much fertilizer is applied to the plant during the growth period, it is easy to cause the branches to grow excessively, so that the nutrients are excessively consumed, and the nutrients needed for bud gestation are taken up.If too much fertilizer is applied during the bud stage, the roots may be burned out, leading to bud drop.In addition, if fertilization is insufficient, it will also hinder the normal growth of plants and hinder flowering.
