What kind of soil is best for growing four-season osmanthus to thrive
Today's sharing: the topic of the flowers and plants, about what kind of soil is best for growing four-season osmanthus and the breeding methods and precautions, please see the detailed introduction below.
The four-season osmanthus prefers deep and fertile soil. For home planting, you can use three parts of sheep manure, one part of garden soil, and one part of river sand mixed together for planting. The osmanthus likes this slightly acidic, organic-rich soil. Generally, after 2-3 years of cultivation, the organic matter content of the soil will gradually decrease, so it is usually necessary to change the soil once every 2-3 years.
There is a very simple method to change the soil for the osmanthus, which is to soak it directly in a slightly larger bucket of water for two hours, after which you can directly remove it from the pot. For newly planted osmanthus, there is basically no need to prune the roots. If it is an osmanthus that has been cultivated for many years, it is necessary to prune the roots a little, trimming the excessively long and aging roots before replanting.
In spring, apply a liquid fertilizer rich in seaweed extract to the osmanthus to supplement various trace elements and allow the roots to grow healthily. In early summer, apply a solution of monopotassium phosphate to promote the differentiation of flower buds, making the branches of the osmanthus stronger. Sprinkling a layer of well-rotted sheep manure in the flowerpot can help prevent soil compaction and also has a moisturizing effect.
Precautions for maintaining osmanthus
In summer and autumn, pay attention to the prevention and control of diseases. The common ones are leaf spot disease, anthracnose, powdery mildew, etc. These diseases are caused by high temperature, high humidity, and poor ventilation and can be prevented and treated with a 800 times dilution of carbendazim spray.
