I had one jade for 27 years until I forgot it outside one fall and the frost got it. *It was about 3' high and wide and had a 3 1/2" thick trunk. *Water is the biggest enemy! *when it was out in direct sun, I watered it about every 4 weeks and when it was inside, I watered it about every 2 to 3 months and it was in a terra cotta pot with a soil mix of 25 % potting soil and 75% #2 poultry grit. *Leave the plant until the leaves start to go limp and then soak the plant with water for about an hour or two and then drain off all excess water. *I fertilized in the spring with whatever fertilizer I had.
