Originating from the warm, dry climate of South Africa's Cape Province, jade plants are very popular as houseplants in coolers regions. With proper care and attention, even indoor plants can grow to 4 feet or more in height. As with any houseplant, they can become root-bound and need re-potting. According to horticulturist Ron Smith of the North Dakota State University Extension Service, jade plants should be transplanted to a new pot at least every three years.
Prepare your potting mix by blending equal part potting soil, peat moss and either perlite or vermiculite. Fill the shallow planting container about half full. The container diameter should be at least twice as large as the existing pot's and of the type used for African violets and similar plants. Be sure it has drainage holes and a proper drainage tray.
Loosen the jade plant from its existing pot by easing a trowel down the side and pulling inwards gently. Grasp the jade plant at the base and slowly pull it out of the pot. If it resists, continue loosening the soil at the edges until the plant will slide out easily. If necessary, remove excess soil from the bottom of the plant so that it will be at the correct height for the new pot when planted. Be careful not to damage the roots.
Place the jade plant in the center of the new container. Fill over the roots with the potting mix to just below the top of the container and gently firm the soil by hand until the plant is stable. Do not compact the soil, as that will affect the drainage.
Water the plant thoroughly. Do not water again until the top of the soil is dry. These plants are susceptible to root rot and should be watered only when the soil has drained. Like most succulents, jade plants store water in their stems and leaves and tolerate dry soil very well.
