1, planting basin

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.

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.

Step 3 apply fertilizer

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 pruning

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.

Osmanthus fragrans is abundant and fragrant.

5, pest control

Laurel has many diseases and insect pests. If it is found, it should be dealt with in time, and special attention should be paid to the prevention and control of whitefly.

The adult whitefly is 1- 1.3mm long, and its body surface is covered with orange thin white powder. In backstab, adults and larvae are clustered, and the juice absorption is damaged to form macula. Its excrement is easy to induce sooty blotch, which makes the branches and leaves turn black and leaves turn yellow and fall off. Control method: When whitefly is found, spray 2.5% * * or 20% metronidazole with 2,000-2,500 times solution, or spray neutral washing powder with 800-4,000 times solution, and spray/kloc-0 every 5-6 days for 3-4 times continuously.

Tips Osmanthus fragrans are usually changed in autumn. When it is planted in soil, be careful not to damage its root system. Add a small amount of base fertilizer when replacing with new soil. When planting, let the roots stretch, don't nest together, and cultivate according to the above maintenance points. Generally, flowers can bloom all year round.
