Choose a ventilated, well-drained, warm place with sufficient sunlight or semi-cloudy environment. Soil balls should be laid well for transplanting to ensure the survival rate. Planting soil should be acidic and avoid alkaline soil. The pot soil of potted osmanthus fragrans is composed of 2 parts humus soil, 3 parts garden soil, 3 parts sandy soil and 2 parts decomposed cake fertilizer. Mix well, then put on the pot or change the pot, before germination in spring.

Watering and fertilizing

Before planting on the ground, plant ash and organic fertilizer were mixed in the tree holes, and watered 1 time after planting. Keep the soil moist before the introduction of new technology, and don't water it with chemical fertilizer. Generally, nitrogen fertilizer is applied 65,438+0 times in spring, phosphorus and potassium fertilizer are applied 65,438+0 times in summer to make flowers flourish, and overwintering organic fertilizer is applied 65,438+0 times before winter, which is mainly composed of decomposed cake fertilizer and stable manure. Avoid thick fat, especially feces and urine. Osmanthus fragrans potted in winter in northern China should be put in a low-temperature greenhouse. Pay attention to ventilation and light transmission indoors, with little water. After leaving the house in April, the amount of water can be increased appropriately, and the amount of light fat water can be poured in the peak season, and the fat water can be slightly thicker in the flowering period.

3. Lighting temperature

In the south of the Yellow River basin, it can be cultivated in the open field for wintering. Potted plants should be moved indoors in winter, placed in a sunny place and fully exposed to direct sunlight. The room temperature should be above 5℃, but not more than 10℃. After germination in April of the following year, it is moved outdoors, first placed in the leeward and sunny place for maintenance, and then gradually moved to a ventilated sunny or semi-shady environment after the growth is stable, and then normal management is carried out. Insufficient light during the growth period affects flower bud differentiation.
