What's the difference between rosemary, lavender and mint?

The optimum temperature for rosemary seed germination is 15-20℃, and the lowest temperature for cutting propagation at night is 13℃. Rosemary likes warm climate, but it grows slowly in high temperature period in Taiwan Province Province, China, and the temperature without cold current in winter is more suitable for its growth. In terms of water supply, because the leaves of rosemary are leathery and more drought-resistant, the soil planted is rich in sandy soil, which is more conducive to growth and development. It is worth noting that rosemary grows slowly, so its regeneration ability is not strong.

The lowest temperature of lavender seed germination is 8 ~ 65438 02℃, and the optimum temperature is 20 ~ 25℃. Lavender is very adaptable. The adult plant is resistant to both low temperature and high temperature, and can withstand high temperature of about 40℃ in harvest season. In Huanglong, Shaanxi, lavender plants overwinter safely in the open field at-265438 0℃. In Xinjiang, it is buried in the soil and covered with snow, which can withstand the low temperature of -37℃. The seedlings can tolerate the low temperature of-10℃. During the growth and development of lavender in the second year, the average temperature is about 8℃, and it takes 10 ~ 15d to start germination. The average temperature is 12~ 15℃, which takes 20 days for plant branches to turn green and grow longer. The average temperature is 16~ 18℃, and it takes 25 ~ 30 days to start budding. The average temperature is 20~22℃, and flowers begin to bloom. The average temperature is 26~32℃, which is the fruiting period.

Propagation of mint rhizome: the culture of seed root is carried out in late April or late August. Peppermint has a strong adaptability to temperature, and its roots can survive the winter and can withstand the low temperature of-15℃. The optimum growth temperature is 25℃-30℃. When the temperature is lower than 15℃, the growth is slow, and when it is higher than 20℃, the growth is accelerated. 20℃-30℃, as long as the water and fertilizer are suitable, the higher the temperature, the faster the growth.
