Longtuzhu prefers a warm, moist and sunny semi-shady environment and is not resistant to cold. The overwintering temperature should be above 15 ℃ and lower than 10 ℃ for a long time, which can cause defoliation to death. If the seed is propagated by sowing or cutting, the seed life is short and it will be sown immediately after harvest.

The suitable temperature for the growth of Longtuzhu was 1824 ℃, 1830 ℃ from February to October, and 1316 ℃ from October to February of the following year. The winter temperature is not lower than 8 ℃, and the stems and leaves above 5 ℃ are easy to suffer from freezing injury. The light ones cause defoliation, and the heavy ones cause the tender stems to wither. During the vegetative growth period, the temperature can be higher, the temperature is higher than 30 ℃, as long as the water supply is sufficient, it can still grow normally. On the other hand, the temperature of reproductive growth, that is, the flowering stage, should be lower, about 17 ℃.
