In the spring and the growing season is quite Aeonium arboreum growing gratifying, the relative demand for water is relatively large, especially in some of the old pile, if found to soften the blade, it is apparent water shortages, and should pay as soon as possible. Winter can be resistant to 5 Celsius low temperature below 5 Celsius, prone to leaf warming, leaves phenomenon.

Aeonium arboreum summer dormancy obvious, mainly state: out of leaves, leaf curling into a rose-like, especially black mage variants, Aeonium arboreum Jin, as well as Aeonium arboreum original species, dormant during the summer heat is very obvious that the state will basically continued to fall.
