Growth habit

Like warm winter and cool summer climate conditions, temperature adaptation range is large, nutritional growth period to adapt to the temperature of 5-28 ℃, higher than 34 ℃ growth inhibition, lower than 3 ℃ to stop the growth of -2 ℃ can withstand the temporary low temperature;

Below -7 ℃ stems and leaves withered, the formation of buds in the period of the appropriate temperature of 16-24 ℃, the requirements of the soil is not strict, but to loose, fertile, drainage and irrigation is convenient!
