A cactus mix with some added organic matter will do. You can also make a mix of one part sterilized organic soil, one part sphagnum peat moss and three parts coarse sand by volume. Fertilize jade plants once every three to four months. A liquid houseplant fertilizer will work well. Wait four months before feeding repotted plants.
Jade plants can live quite happily for years while root-bound.
If repotting is necessary, do it as new growth starts. When your plant becomes older and top-heavy, move it to a large, heavy pot to prevent tipping over. Allow the soil to become dry after repotting. You can start new plants from stem cuttings. This jade is similar to the more frequently grown C. ovata but has blue-gray leaves with red margins.
