Temperature

Lavender is highly adaptable. Adult plants are resistant to both low temperature and high temperature, and can withstand high temperatures of about 40°C during the harvest season. In the Huanglong area of ??Shaanxi, lavender plants can survive the winter safely in the open at -21°C; in Xinjiang, they can withstand low temperatures of -37°C after being buried in soil and covered with snow. Seedlings can tolerate low temperatures of -10°C.

Moisture

Lavender is a plant that likes dryness and does not require much water. The annual rainfall is 600~800mm. During the regreening and budding stages, the plants grow faster and require more water; during the flowering stage, less water is required; during the fruiting stage, the amount of water should be appropriate; during the winter dormancy period, winter irrigation or snow cover is required. Therefore, the ideal rainfall distribution throughout the year is abundant in spring, moderate in summer, and sufficient snow in winter.

Sunshine

Lavender is a long-day plant. It requires sufficient sunshine during the growth and development period, and requires more than 2000 hours of sunshine throughout the year. If the plant is in a damp and humid environment, it will develop poorly and age quickly.

Soil

Lavender has a well-developed root system and prefers fertile soil with deep, loose, well-ventilated soil rich in silicon and calcium. Strongly acidic or alkaline soil and plots with heavy clay, poor drainage or high groundwater levels are not suitable for planting. ?
