How to grow lavender (for several months)

Lavender can be cultivated by sowing or cutting. Sowing can be carried out in spring (March-June) or autumn (September-November) every year, and the germination days are about 15 days. If you buy a potted plant from a florist, you can also cut and plant it by yourself. you can choose the top bud (about 5 ~ 10), remove the leaves from the bottom 2 nodes, and then cut them in the soil after 2 hours of water. it will take root in about 2 or 3 weeks. The cutting medium can be mixed with the coarse sand of 2 stroke 3 and the peat moss of 1 stroke 3.

Planting method of lavender

1, sowing method: generally larger seeds (such as lavender, sage), you can order 2-3 seeds in each container. After germination, depending on the growth status of the seedlings, leave a stronger one, and the seeds are small (such as Mayoram). Sow some seeds with your hands, sow them gently on the soil, and plant seedlings after germination. Leave 1-3 seedlings as appropriate.

2. Seed covering soil: the thickness of seed covering soil depends on the seed size, which is generally 2 to 3 times the seed diameter, the fine seed soil is thinner, lavender seeds can be thicker, and some seeds have strong phototaxis. Can not cover the soil (such as vanilla, Rosemary).

3. Watering: lavender does not like the retention of water in the roots. After one-time watering, the soil should be fed again when the soil is dry. The surface culture medium is dry, the interior is moist, and the leaves wilt slightly. Water in the morning, avoid the sun, do not splash water on leaves and flowers, otherwise it is perishable and breeds diseases and insect pests. A continuous humid environment will cause the roots not to breathe enough air and grow poorly, or even suddenly die of the whole plant, which is often the reason for the failure of lavender cultivation.

Matters needing attention in planting lavender

The main results are as follows: 1. the newly planted seedlings and perennial seedlings will be plucked and released at the end of May next year, and watered when the temperature rises, so as to determine the roots of the young seedlings and pour the key water for the old seedlings to return to green. After a week of watering, loosen the soil, preserve soil moisture and increase temperature. In the old seedling field, 19kg of urea, 15kg of calcium superphosphate and 30kg of oil residue were applied to the old seedling field. In order to play the role of fertilization, loosening the soil, preserving soil moisture and raising temperature, it is conducive to the green growth of lavender in spring.

2. Newly planted seedling plots should be well watered, watered 4 or 5 times a year, and ploughed and weeded in time. The flower buds appeared before June 20 should be knocked out in time to promote multiple branches of the plant, so as to lay a foundation for the formation of yield in autumn and high yield in the coming year. For the old seedling plot, there should be no weeds in the field, and the budding water should be watered in early May and the flowering period in June.

Prevention and Control of Diseases and insect pests of Lavender

1. Lavender leaf spot: the main prevention and control method is to spray Bordeaux solution 1V200 to prevent 2x 3 times, or Dyson zinc 500 times 800 times. Red spider

2. Red spider of lavender: its control methods mainly include timely treatment of dead branches and leaves, cleaning up the environment to destroy the living place of spider mites, correct farming methods, reasonable crop rotation, strengthening water and fertilizer management, protecting natural enemies, releasing natural enemies, and controlling insects with insects. In addition, there are also control methods: at the initial stage of the occurrence of the disease, 0.26% matrine was sprayed evenly with 1000 times of matrine, and when it occurred in a large area, it was sprayed evenly with 20% dicofol EC 1000 × 2000, or 1.8% avermectin EC 3000-4000 times. The control effect is better.

When planting lavender, you must understand its growth habits, and then choose an appropriate time to plant. The management should be strengthened in the later stage of planting, especially in the aspects of fertilizer and water and diseases and insect pests. Only by doing a good job can lavender grow healthily.
