1. Sowing seeds
The sowing time of lavender is generally spring, the warm area can be carried out in March-June or September-November every year, the cold area should be sowed from April to June, and it can also be sowed in greenhouse in winter, the germination time is about 14-21 days, and the optimum germination temperature is 18-24 ℃. Proper light is needed after germination, and weak light is easy to grow in vain.
A. most areas choose to sow in spring.
B. Sow seeds in warm areas from 3 to 6 and from September to November.

C, be careful not to cut the lignified part when pruning, so that the plant will not be weak and die.
7. Disease and insect
A, leaf spot disease
Spray Bordeaux solution 1 ∶ 200 to prevent 2-3 times or Dysen zinc 500-800 times.
B. root rot, Fusarium wilt
Use 50% carbendazim 500 times solution or 50% methyl topiramate 400 times solution to irrigate roots or leaves.
C, red spider
Dilute the solution 6-1000 times with 1.8% avermectin, or foliar spray such as dicofol.
D, leafhopper, jumping beetle
Pyrethroids such as 50% phoxim EC, 50% fenitrothion EC and 12% insecticidal crown EC were used for control.

How to raise potted lavender?
Lavender, also known as spirit vanilla, vanilla, yellow vanilla, etc., is a small shrub plant of the genus Lavender of Labiatae. Its leaf shape is beautiful and elegant, and its blue-purple inflorescences are long and beautiful. It is often used as a new perennial cold-resistant flower in the courtyard, which is suitable for planting flowers in clusters or strips. It can also be watched by potted plants. Let's take a look at how to raise potted lavender.
Growth habits of lavender
Lavender has strong adaptability. The adult plants can tolerate both low temperature and high temperature, the high temperature is about 40 ℃ in the harvest season, and the seedlings can tolerate the low temperature of-10 ℃. The plants that like to be dry and do not need much water need more water in the green stage and bud stage, less in the flowering stage and suitable in the fruiting stage. Belongs to the long sunshine plant, the growth and development period requires sufficient sunshine, the annual sunshine hours are required to be more than 2000 hours. The root system is well developed, and the sex likes the fertile soil with deep, loose, good air permeability and rich silicon and calcium.
Propagation methods of lavender
1. Sowing: the sowing time of lavender is generally spring, the warm area can be carried out in March-June or September-November every year, the cold area should be sowed from April to June, and it can also be sowed in greenhouse in winter. The germination time is about 14-21 days, and the optimum germination temperature is 18-24 ℃. Proper light is needed after germination, and weak light is easy to grow in vain.
2, cuttage: lavender cuttings are generally carried out in spring and autumn, and softwood cuttings can also be done in summer. The medium of cuttings can be mixed with coarse sand of 2 hand 3 and peat moss of 1 hand 3. Under the condition of good drainage, keeping moist, 20: 24 ℃ bed temperature, about 40 days will take root. Do not use the terminal bud cuttings where inflorescences have appeared, because the flowering branches have aged and the rooting will adversely affect the future growth.
3. Ramet: the ramet propagation of lavender can be carried out in spring and autumn, using 3-4-year-old plants, and separated by adult roots from March to April in spring, with bud eyes on each branch.
How to raise potted lavender?
1. Soil: lavender is suitable for slightly alkaline or neutral sandy soil. Special attention should be paid to selecting media with good drainage. Perlite, vermiculite and peat moss should be mixed and used. If it is cultivated in the open field, we should pay attention to the drainage of the soil, and the soil can be piled high into a bed before planting.
2. Watering: lavender does not like the retention of water in the roots, so it should be fed again when the soil is dry after once watering. 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.
3. Lighting: lavender is an all-day plant, which needs sufficient sunlight and humid environment. The environment that can give full sunshine is better. Half-day sunshine can also grow, but flowering is rare. Summer should cover at least 50% of the sun and increase ventilation to lower the ambient temperature, so that although the growth is weak, it does not die. Lavender can grow well on flat land in winter and should be cultivated under full-day sunshine.
4, temperature: lavender is semi-heat-resistant, cool, warm in winter and cool in summer, the suitable temperature for growth is 15: 25 ℃, it can grow at 5: 30 ℃, the limited temperature is above 35 ℃, and the top stems and leaves are yellow above 38: 40 ℃ for a long time. In northern China, dormancy begins when it is below 0 ℃ for a long time in winter, and the seedlings can tolerate a low temperature of-20 ℃ per square meter during dormancy.
5. Fertilization: lavender fertilizer can put bone meal in basin soil as base fertilizer (once every three months), seedlings can apply Huabao No. 2 (20 / 20 / 20 / 20), and then apply fertilizers with higher phosphate fertilizer such as Huabao No. 3 (10-30 / 20). Apply light fertilizer, lavender should not be fertilized too much, otherwise the fragrance will fade.
6. Pruning: lavender must be pruned after flowering, and the plant can be trimmed to the original 2par 3, which will be sturdy and conducive to growth. Pruning in the cold season such as spring and autumn, generally pruning in spring, pruning in autumn will affect the cold resistance. Be careful not to cut the lignified part when pruning, so as not to weaken the plant and die.
7. Diseases and insect pests: lavender leaf spot disease is sprayed with Bordeaux solution 1 ∶ 200 to prevent 2 times or 800 times of Dysen zinc. Root rot and Fusarium wilt were sprayed on roots or leaves with 50% carbendazim 500 times or 50% methyl topiramate 400 times. Red spiders dilute 600 × 1000 times with 1.8% avermectin, or foliar sprays such as dicofol. Leafhoppers and jumping beetles are controlled with pyrethroids such as 50% phoxim EC, 50% fenitrothion EC and 12% insecticidal crown EC.
