1. Never water it. 2. Leave it on the porch for 2 months without water. 3. Water said plant and check and make sure some of it is still alive. 4. Cut off dead parts. (More than half of the plant). 5. Hang plant back on porch and try not to forget it for another two months.
In my defense, I did NOT inherit any of my family's green thumbs - nor have my mother in law's gardening skills rubbed off! But I have managed to keep this plant alive for 13 years (I took it college with me!)
