1. Soil: Sweet osmanthus likes slightly acidic soil, which can be mixed with humus or peat, garden soil and sand.
2. Watering: less watering before new shoots grow, less watering in rainy season in cloudy days, more watering in dry summer. Watering should be appropriate to prevent water accumulation in the basin soil. In summer, watering should be sufficient. Watering can be done once in the morning and once in the evening. At noon, shading measures should be taken, and water can be sprayed around, so as to achieve the effect of cooling.
3. Fertilization: after germination, apply fertilizer and water to the rotten pancakes every 10 days. In July, apply compound organic fertilizer. In September, apply phosphorus fertilizer to help it grow and bloom.
4. Light: Sweet osmanthus likes sunshine. It receives about 8 hours of light every day during flower bud differentiation period. In winter, the temperature is too low and the light is insufficient, which will lead to falling leaves. Therefore, it is necessary to take proper measures to keep warm.
1. Sowing and propagation: remove the shell of the mature stone fruit, dry it and store it, and then sow it in the early spring of next year. When the weather warms, it will take root and sprout.
2. Cuttage Propagation: remove the tender leaves at the top of the cuttings, cut all the leaves at the bottom, leave a pair of leaves at the top, and insert them into the soil. Shade is needed in sunny days.
1. Brown spot: remove the diseased branches and leaves in time, spray 1000 times potassium permanganate solution, and strengthen ventilation to avoid being drenched by rain.
2. Leaf blight: it is easy to aggravate in high temperature and high humidity environment. Clean and burn the diseased leaves to avoid increasing the source of infection. Loosen the soil frequently. Water in time in case of dry weather to increase its disease resistance.
