I. planting method of lavender

The sowing time is generally spring, warm areas can be carried out in March-June or September-November every year, cold areas should be sown from April to June, and sowing can also be sowed in greenhouse winter. The time of germination is about 14-21 days. The suitable temperature for germination is 18-24 ℃. Proper light is needed after germination, and weak light is easy to grow in vain. Seeds should be soaked for 12 hours before sowing and then soaked with 20-50ppm gibberellin for 2 hours before sowing because of their long dormancy period. Before sowing, smooth and fine soil, pour through water, after underwater infiltration, evenly sow seeds, and then cover with a layer of fine soil, thickness of 0.2 cm, covered with plastic film to preserve moisture. Keep the seedling bed moist for 15-25 ℃, and the seedlings will emerge in about 10 days. If gibberellin is not used, it will take a month to germinate. It takes 1-3 months to germinate when the temperature is less than 15 ℃. Pay attention to spraying water in the seedling stage, when the seedlings are too dense, they can be suitable for seedlings, and when the seedlings are about 10 cm high, they can be transplanted.

Can lavender be planted in the north

Yes.

[growth habits]

1. Lavender has strong adaptability. The adult plant can tolerate both low temperature and high temperature, and the high temperature is about 40 ℃ in the harvest season. In Huanglong area of Shaanxi Province, lavender plants survive the winter safely in the open field at-21 ℃.

2. In the * * area, the low temperature of-37 ℃ can be withstood by buried soil treatment and snow cover.

3. The seedlings can tolerate the low temperature of-10 ℃.

4. During the growth and development of lavender in the following year, the average temperature is about 8 ℃, and it takes 10 to 15 days for lavender to germinate.

5. When the average temperature is 12-15 ℃, it takes 20 days for the branches to turn green and elongate.

6. The average temperature is 16-18 ℃, and it takes 25-30 days to begin budding.

7. The average temperature begins to bloom at 20: 22 ℃, and the average temperature is at 26: 32 ℃, which is the fruiting period.

III. Planting time and methods

[cultivation environment] lavender likes warm climate, cold tolerance, drought tolerance, light tolerance and fear of waterlogging. It has lax requirements on soil, resistance to barren, and prefers neutral alkaline soil with loose and good drainage. Lavender is difficult to be planted in the south because it is not resistant to waterlogging, but as an aromatic plant, lavender is an excellent potted flower.

[sowing] Lavender seeds are small and suitable for seedling transplanting, sowing and seedling raising at any time in warm areas and spring sowing in cold areas. Before sowing, the land is leveled and watered, and after the water seeps, the seeds are evenly sown, then covered with a layer of fine soil, which is 2-3 times thicker than the seeds, and covered with grass or plastic film to preserve moisture.

[watering] lavender likes a dry environment and is not resistant to moisture. Families should avoid frequent watering. The basin soil or ground should not be watered, so it should be ventilated. Pour water once after putting on the basin, and the principle of watering after survival is "see dry and wet". When watering, we should pay attention to that the water should not be poured directly on the leaves, nor should the soil be splashed on the branches and leaves to avoid diseases. It can also spread a layer of pebbles on the soil surface of the flowerpot, which is not only beautiful, but also can prevent disease. If you use tap water, it is best to use it in the sun for two days.

[Rizhao] Lavender is a long-sun plant, light plays a very important role in its development and the formation of aromatic oils, excessive shading will cause overgrowth and susceptibility to disease, but it is best to do some shading treatment in hot heat to avoid direct sunlight.

[fertilization] Lavender does not have high requirements for fertilizer. In the spring when it grows rapidly (March-May), compound fertilizers of nitrogen, phosphorus and potassium can be applied monthly, and the solution can be irrigated with a concentration of 1%. Too much nitrogen fertilizer can easily lead to futile growth.

[plastic] after flowering, cut off the first node under the flower and trim the plant into a hemispherical shape. Usually, cut off the dry branches at any time. In order to control plant height or get better plant type, proper re-pruning in late summer and early autumn to promote new shoots. When the seedling is too dense, it can be suitable for the seedling, and when the seedling height is about 10CM, it can be transplanted. It grows rapidly and needs to be changed once a year.

[pest control] there are few pests. The disease is mainly root rot, which has the highest incidence in high temperature and stagnant water environment. Prevention and cure method: irrigate the root with 800 times solution of carbendazim and chlorothalonil once a month, especially from June to October, pay attention to prevent stagnant water and keep the air dry.
