It is adapted to a precipitation zone of 750 to 1200 mm/yr with prolonged periods of drought. It has a temperature range of -10 to 40°C and is frost hardy. It prefers a sub-humid, cool to semi-arid, warm sub-tropical winter/monsoon climate, usually at elevations from 500 to 2500 m.

Uses :

This is a very valuable tree as it produces both food and fodder and will grow on poor, and draughty sites. It is sometimes considered an "evergreen" because as the old leaves drop new leaves develop. It is a critical source of fodder in the colder periods of the year. The fodder is highly palatable and is used for forage in the sub-mountainous regions. Also used in tool handles, agriculture implements, fodder, food (fruit), and cordage. The inner bark is also used to make rope. A good farm forestry tree.
