Osmanthus fragrans likes acidic soil, but the requirements are not high. You can dig some soil at will, but don't buy humus soil for raising meat, just ordinary soil. First, put a layer of fine sand in a flowerpot of suitable size to make it permeable, or don't put it. Spread another layer of soil, and then pour the soil into the greenhouse until it is about five centimeters lower than the flowerpot, which is convenient for watering and fertilization. Then put some water of rooting powder, water it again, and water it when it is dry. When pruning, use special tools to cut off diseased and dead branches, and cut off redundant branches. In order to keep osmanthus indoors, it is not allowed to grow too high. Generally, the main branch will be cut off and it will grow into an umbrella. Trim it about twice a year. At the same time, appropriate fertilization should be applied to ensure the healthy growth of osmanthus fragrans, which is flourishing and fragrant.
