1. Sowing and reproduction
Lavender can be propagated by harvested seeds. Sowing early in the south can be selected from March to June, and the north suggests that from April to June, the optimum temperature for germination is 1824 ℃, and the germination period is usually 2-3 weeks.
2. Selection of basin soil
Lavender is suitable for slightly alkaline or neutral sandy soil. The soil should choose a medium with good drainage, which can be mixed with perlite, vermiculite and peat moss. 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.
3. Watering
Lavender watering should choose morning or evening, watering should follow the principle of no drying and no watering. Watering should be directly irrigated in the soil to prevent plant diseases and insect pests caused by water, at the same time should avoid plants in a humid environment for a long time, easy to rot root necrosis.
4. Lighting
Lavender is a sunny plant, and the all-sunshine environment is beneficial to plant growth. Summer high temperature weather should pay attention to shading, ventilation, to avoid exposure, easy to dry up due to water loss of basin soil. Lavender can grow well on flat land in winter and should be cultivated under full-day sunshine.
5. Temperature
Lavender has a certain degree of heat resistance, cool in summer and warm in winter. The suitable temperature for growth is 15-25 ℃, and it can grow at 5-30 ℃. The limiting temperature is above 35 ℃, which is higher than 38-40 ℃ for a long time. The top stem and leaf are withered and yellow. 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.
6. Fertilization
Lavender should not be fertilized too much, otherwise the fragrance will fade, so lavender fertilization should be based on the principle of diligent application, less application, nitrogen stele and potassium. Basal fertilizer is applied to seedlings, topdressing before flowering, but not fertilizing after anthesis.
7. Diseases and insect pests
Lavender is rarely infected because its own taste can deworm, but the common disease is rot, root rot, which needs to be treated with carbendazim.
