1, seed pot. Osmanthus fragrans doesn't require much soil, but alkaline soil or clay can't be used, and slightly acidic loam is better. Pot maintenance and pot soil preparation must pay attention to the use of loose and fertile substrates with good drainage, and the flowerpot should be deeper, so that the soil layer can be deeper and the root system of osmanthus fragrans can have enough room for growth. After planting Osmanthus fragrans seedlings in pots, shake the flowerpots to make the culture soil closely contact with the roots, then water them and keep them indoors.

2. water. Water osmanthus fragrans in the middle of the month should master "two less and one more", that is, "less" before the emergence of new buds, "less" in rainy days and "more" in dry days in summer and autumn. In addition, when watering laurel trees, it is advisable to always keep the water content of basin soil at about 50%, and drain it in time in rainy days to prevent the water in the basin from rotting.

3. Fertilize. Osmanthus fragrans should pay attention to fertilization after germination in spring. We can apply 1 times of fully decomposed cake fertilizer every 10 day, which can promote osmanthus fragrans to produce new branches. When you spend money, you can switch to liquid fertilizer based on phosphate fertilizer, which can promote the differentiation of osmanthus flower buds and make osmanthus plants grow vigorously and bloom more and more fragrant. If there is not enough phosphate fertilizer, the laurel branches in Na Yue will be few and the flowers will not be fragrant.

4, plastic trimming. Osmanthus fragrans has developed root system and strong germination ability. Adult osmanthus trees should be photographed twice a year. In order to make Osmanthus fragrans flourish, it should be pruned properly to keep the balance between reproductive growth and vegetative growth. Generally, it is necessary to cut off long branches, thin branches and branches of pests and diseases, so as to facilitate ventilation and light transmission, concentrate nutrition, and promote osmanthus fragrans to breed more and fuller flower buds, and then bloom luxuriantly. But pruning should not be excessive, otherwise it is easy to sprout branches and affect the number of flowers.
