How to raise Osmanthus fragrans

I. Culture environment

1. Soil: sweet-scented osmanthus likes slightly acidic soil and can be mixed with humus soil or peat, garden soil and sandy soil.

2. Watering: less watering before new shoots grow, less watering in cloudy and rainy season, and more watering in dry summer. Watering should be appropriate not to allow stagnant water in the basin soil, sufficient watering in summer, watering once in the morning and evening, shading measures should be adopted at noon, and water can be sprayed around to achieve the effect of cooling.

3. Fertilization: mature thin cake fertilizer and water is applied every 10 days after germination. Compound organic fertilizer is suitable for July, and phosphorus fertilizer in September can help it grow and bloom.

4. Lighting: sweet-scented osmanthus likes sunshine and receives about 8 hours of light every day during flower bud differentiation. If the temperature is too low and the light is insufficient in winter, it will lead to fallen leaves, so appropriate measures should be taken to keep warm.

II. Methods of reproduction

1. Sowing and reproduction: remove the shell of the ripe drupe, wait for it to dry and store it, and sow it in early spring next year. It will take root and sprout when the weather gets warmer.

2. Cutting propagation: remove the young leaves at the top of the cuttings, cut off all the leaves at the lower end, leave a pair of leaves at the upper end, and insert them into the soil. Sunny days need shade.

Third, common diseases

1. Brown spot: to remove diseased branches and leaves in time, 1000 times potassium permanganate can be sprayed, and ventilation should be strengthened to avoid being drenched by rain.

2. Leaf blight: the disease is easy to aggravate in the environment with high temperature and humidity. It is necessary to clean up the diseased leaves and burn them, so as not to increase the source of infection, loosen the soil frequently, and water in time in case of dry weather to increase its disease resistance.
