Because lavender is sunny, heat-resistant, drought-tolerant, extremely cold-resistant, resistant to thinness, and resistant to salt and alkali, the cultivated field requires sufficient sunshine and good ventilation. The time required for sowing to flowering (or harvesting) is 18 to 20 weeks. lavender
Soil: Suitable for slightly alkaline or neutral sandy soil. Special care must be taken to select a well-drained medium that can be used after mixing 1/3 of pearl stone, 1/3 of vermiculite, and 1/3 of peat moss. If you are paying attention to soil drainage when planting in open field, you can plant the mounds high and then plant them.
Watering: Lavender does not like the roots often have water retention. After the water is poured once, the water should be supplied when the soil is dry, and the surface culture medium is dried, the internal humidity is degree, and the leaves are slightly wilted. Watering should be done in the morning, avoiding the sun, and the water should not splash on the leaves and flowers, otherwise it will perish and breed pests and diseases. A persistently humid environment will cause insufficient root breathing in the roots to grow poorly, and even suddenly the whole plant will die.
Illumination: Lavender is a full-day plant that requires sufficient sunlight and a humid environment to give a full-light environment. Half-day sunshine can also grow, but flowering is rare. At least 50% of the sunlight should be removed in the summer, and ventilation should be added to lower the ambient temperature, so that although the growth is weak, it does not die. Lavender grows well on the ground in winter and should be cultivated under full sunlight.
Temperature: Lavender is semi-heat resistant, cool, warm in winter and cool in summer, suitable for growth: 15 ~ 25 ° C, can grow at 5 ~ 30 ° C. Limit temperature: above 35 °C, long-term higher than 38 ~ 40 °C top stem leaves yellow. In the winter in the north, the dormancy begins at 0 °C for a long time, and the seedlings can withstand a low temperature of -20 to -25 °C during dormancy.
Fertilization: The bone powder can be used as the base fertilizer in the potting soil (used once every three months), the small seedlings can be applied to Huabao No. 2 (20-20-20), and the higher the fertilizer with the higher phosphorus fertilizer such as Huabao No. 3 (20-30-20). Apply light fertilizer.
Pruning: Lavender flowers are the most abundant in essential oils. When used, they are mainly flowers or inflorescences. For the convenience of harvesting, some small inflorescences in the early stage of cultivation may be flattened with large scissors. The new inflorescences are highly consistent and conducive to one harvest. Some varieties can reach a height of 90 cm. This method is also used to make plants low and promote branching, flowering and increase harvest. After the flower is finished, it must be trimmed, and the plant can be trimmed to 2/3 of the original, the plant type will be firmer and will be beneficial for growth. When pruning, it should be trimmed in the cool season, such as spring and autumn, usually in spring, and trimming in autumn will affect cold resistance. Be careful not to cut the lignified part when trimming, so as to prevent the plant from dying and dying.
There are mainly methods such as sowing, cutting, layering, and rooting . At present, the cutting method is mainly used in production, so that the inherent quality of the mother is maintained.
Sowing: Lavender seeds are small and should be transplanted. The sowing period is generally selected in spring, warm areas can be carried out from March to June or September to November every year, cold areas should be planted from April to June, and can be planted in the greenhouse in winter. The number of germination days is 14 to 21 days. Germination temperature: 18 ~ 24 ° C. After germination, proper illumination is required, and weak light is easy to grow. Seeds should be soaked for 12 hours before sowing because of a longer dormancy period, then soaked with 20-50ppm gibberellin for 2 hours and then sown. Before planting, the land is flat and fine, and the water is poured. After the underwater seepage, the seeds are evenly spread, and then covered with a layer of fine soil, the thickness is 0.2 cm, covered with grass or plastic film to protect the sputum. Maintain 15 ~ 25 ° C, the seedbed is required to be wet, about 10 days to emerge. If it is not treated with gibberellin, it will take one month to germinate. It takes 1 to 3 months to germinate below 15 °C. At the seedling stage, pay attention to water spray. When the seedlings are too dense, the seedlings can be properly placed. When the seedling height is about 10 cm, it can be transplanted.
Cutting propagation: cuttings are generally carried out in spring and autumn. Summer twig cuttings are also available. The cutting media can mix 1/3 of the peat moss with 2/3 of the coarse sand. Select the well-developed and good-growing strains, and select the annual semi-lignified shoots with short, thick and unearthed shoots, and cut the cuttings at the top 8-10 cm. The incision of the cuttings should be near the stem section, and strive to be smooth, so that the phloem is not broken. Remove the leaves from the bottom 2 sections, insert the water for 2 hours, then insert the soil into the soil, and root it in 2 to 3 weeks. It can also choose 8~10cm annual branches, which are well-drained and kept moist. Under the condition of 20~24°C bed temperature, rooting takes about 40 days. Do not use the top buds that have already appeared inflorescences, because the flowering branches are aging, which will adversely affect the future growth. The mulch is cut and the ground is made. After pouring water, cover the film and cut it immediately. It is 5 to 8 cm deep and 20 to 25 cm apart. Pay attention to increase the ground temperature and promote root development; pruning and extending branches, picking up flower spikes in time, promoting branching, and cultivating strong seedlings. The planting distance was 60cm and the row spacing was 120cm. Water immediately after planting.
The ramets can be carried out in spring and autumn. Plants with 3-4 years old are divided into adult roots in spring and 3-4 months, each with bud eyes.
Planting environment needs
The seeds of lavender are small and suitable for seedling transplanting. In warm areas, seedlings can be planted at any time throughout the year, and cold areas should be planted in spring. Before sowing, the land should be flat and fine, and the water should be poured. After the water is infiltrated, the seeds are evenly spread, and then covered with a layer of fine soil, the thickness of which is 2-3 times of the seed, covered with grass or plastic film.

After pouring the water in the upper basin, the principle of watering after the survival is “see dry and wet”. When watering, be careful not to pour the water directly onto the leaves, and do not let the soil splash on the branches and leaves to avoid disease. You can also lay a layer of small stones on the surface of the flower pot, which is both beautiful and disease-proof. If you use tap water, it is best to use tap water in the sun for two days.

After flowering, cut off at the first section of the flower and pruning the plant into a hemisphere. Usually, cut off the dry branches at any time. In order to control the height of the plant or get a better plant type, it is appropriately re-cut in the late summer and early autumn to promote new shoots. When the seedlings are too dense, they can be properly planted. When the seedling height is about 10CM, they can be transplanted. It grows rapidly and needs to be changed once a year.
There are few pests. The disease is mainly root rot, which has the highest incidence in high temperature and stagnant water environment. Control method: use carbendazim, chlorothalonil 800 times solution to fill the roots, once a month, especially June to October, pay attention to prevent water accumulation, keep the air dry.
