The osmanthus tree does not grow new leaves, and some measures need to be taken to solve this problem. First of all, the soil quality needs to be checked. Osmanthus trees need to grow in well-drained, fertile, slightly acidic soil, if the soil is too clayey, too alkaline or lacks nutrients, it will affect the growth of the root system, which in turn will affect the growth of new leaves. Therefore, it is necessary to replace the soil or improve the soil to make it suitable for the growth of osmanthus.
Secondly, it needs to be watered properly. Osmanthus trees prefer a moist environment, but they are also afraid of waterlogging, and if they are watered too much or too little, they will cause damage to the root system and affect the growth of new leaves. Therefore, it is necessary to adjust the watering method in time according to the dry and wet conditions of the soil to keep the soil moist and moderate.
Third, proper fertilization is required. Osmanthus trees need sufficient nutrients to grow properly, and if there is not enough fertilizer or the right way of fertilization, it will cause the growth of new leaves to be stunted. Therefore, it is necessary to fertilize reasonably according to the growth of osmanthus, you can use well-rotted organic fertilizer or compound fertilizer, pay attention to control the amount and concentration of fertilizer, and avoid burning roots.
Fourth, pests and diseases need to be controlled. Osmanthus trees are susceptible to pests and diseases, and if the pests and diseases are severe, it will affect the growth of new leaves. Therefore, it is necessary to regularly check the growth of osmanthus trees to detect and control pests and diseases in time. Methods such as biological control and chemical control can be used to control pests and diseases.
Finally, proper pruning is required. The pruning of osmanthus trees is very important, if it is not pruned properly, it will lead to the stunting of the growth of new leaves. Therefore, it is necessary to prune in time according to the growth of osmanthus trees, remove weak branches, diseased branches and cross branches and other bad branches, so that nutrients are more concentrated for the growth of new leaves. At the same time, the growth of new leaves can be promoted by topping, topping, etc.
In short, if the osmanthus tree does not grow new leaves, it needs to start from many aspects, such as improving soil quality, reasonable watering, proper fertilization, pest control and reasonable pruning. Only a comprehensive approach can restore the health and thrive of the osmanthus tree.
