Keeping Jatropha curcas L. in the office
The Jatropha plant does not resist to frost. It has to be kept inside the house during winter time.
To water it once a week is enough. Better dry as too wet.
If the plant looses its leaves, which is very normal, give it less water, only all 2 or 3 weeks. After 1 to 3 months there will grow new leaves.
If the plant get too big, just cut it. It will grow new branches soon.
I didn't observe flowering yet.
