How to grow osmanthus indoors and what to pay attention to

Osmanthus growth habits

Osmanthus is suitable for growing in areas with subtropical climates. It likes a humid and mild environment. The suitable growth temperature is around 15 degrees. It likes sunlight and needs more than 6 hours of sunlight a day. Adequate sunlight is conducive to the growth of flower buds and can enhance the ornamental value of the plant.

Light requirements: Osmanthus loves light, especially when cultivated for the purpose of promoting flowering, it should receive as much light as possible. Only with sufficient light can it produce and accumulate nutrients at a higher level, and nutrients are the material basis for flowering.

Growth temperature: The suitable indoor growth temperature for osmanthus is between 15 degrees and 28 degrees. It should be moved indoors for the winter, and the indoor temperature should be controlled between 0 degrees and 5 degrees.

Indoor cultivation method of osmanthus

Osmanthus is not very demanding on the soil, as long as it is loose and has good drainage. The most suitable temperature for the plant's growth is between ten and thirty degrees. It likes a slightly dry environment, but the temperature is high in summer and water evaporates quickly. You can water it every day and apply some thin fertilizer in time to meet its nutrient needs.

Indoor watering of osmanthus: Osmanthus has a certain degree of drought resistance. It should be watered in moderation and no water accumulation should occur. It can be watered every day in summer with an appropriate amount of spraying. In winter, when the temperature is lower, water it once every 10 days or so. After watering, it is best to loosen the soil to facilitate root absorption. If tap water is used, it should be left to stand for 2-3 hours in advance.

Fertilizing osmanthus: When planting osmanthus, you can apply some base fertilizer. During the growth period, mainly apply liquid fertilizer. Note that the concentration of the fertilizer cannot be too high. It needs to be diluted with water. Generally, it is applied once every 15 days. Nitrogen fertilizer is mainly used in spring. Phosphorus and potassium fertilizers are applied before flowering. When fertilizing, be careful not to apply it at noon when the temperature is highest, and do not use raw fertilizer.

Osmanthus pruning: Osmanthus can be pruned in early spring, mainly by pruning away overgrown branches, overcrowded branches, thin branches, diseased and insect-infested branches, and dry branches to reduce nutrient loss. Branches and leaves that affect the appearance can also be pruned away to enhance the ornamental value of the plant.

Osmanthus can be propagated by cuttings in spring. Choose strong one-year-old branches with a length of 5-10 cm, cut off the lower leaves, leave 2-3 green leaves on the upper part, insert into loose soil, water thoroughly once, maintain in a cool place, maintain the temperature at 20-25 degrees, and it can take root and be transplanted after 2 months.

Precautions for indoor maintenance of osmanthus

Osmanthus can be repotted in spring, and the plant is relatively cold-resistant, so it can overwinter in the open field in areas south of the Qinling Mountains and the Huaihe River in China. In the northern regions, good warming measures need to be taken. If it is moved indoors for maintenance, sufficient light must be provided to promote the formation of flower buds.
