How to cultivate golden osmanthus

1. Maintenance methods

1. Temperature: Osmanthus fragrans likes warmth, which can be seen from its main distribution areas. Generally speaking, eighteen to twenty-five degrees is more suitable. Its cold resistance is not particularly good, so try to adjust it slightly in winter and don't let the temperature drop below ten degrees.

2. Light: Golden osmanthus loves light and must have sufficient sunlight to bloom better. Otherwise, its growth will be affected and it may even grow too tall, affecting its shape. However, strong light needs to be avoided, otherwise it will burn its leaves and flowers. Generally speaking, only a little shade in the summer is enough.

3. Watering: Osmanthus fragrans likes moisture, and the seasons that require the most water are one month after planting and in summer. It needs to be watered thoroughly each time and the humidity of the air needs to be controlled. However, it is not tolerant to waterlogging, so just water it thoroughly and avoid water accumulation.

4. Fertilization: Fertilizer should be added according to the principle of "apply small amounts of fertilizer frequently". Nitrogen fertilizer is mainly used during the growth period. Before winter, some inorganic fertilizers are needed.

2. Breeding techniques

1. Reproduction: It can be propagated by cuttings. This can be done from May to mid-July or from September to mid-October. Light loamy arable land can be used as a location for cuttings. The soil must be tilled before planting. It is best to trim the cuttings before inserting them, and the insertion depth should be two-thirds of the entire length. Afterwards, water should be sprayed and appropriate shade measures should be taken.

2. Pruning: The first step is to peel off the buds, which means peeling off the useless buds when the plant sprouts. The next task is thinning the branches, which is to cut off some of the branches that are too dense to avoid affecting the degree of light transmission. The last step is pruning, which targets the overgrown branches. They are cut short to control their overall height.

3. Problem diagnosis and treatment

1. Disease: From July to October, the main disease is leaf blight, which causes a large number of leaves to dry up and fall off. You can use Class A thiophanate-methyl for prevention and control, and control the density and clean up the surrounding fallen leaves.

2. Pests: The main types of pests are aphids and scale insects, which can be controlled with alcohol or other pesticides.
