If kept indoors, make sure the jade plant is receiving adequate sunlight. Jade plants kept indoors or in the shade maintain a deep, emerald or dark green color on their leaves. You’ll know if they are not receiving adequate sunlight by the way they grow. Jade plants prefer a potting mix that is fast draining. They do not like to sit in wet soil for too long. If the soil stays constantly wet, the plant becomes susceptible to fungus, diseases, and root rot. As a rule of thumb with watering jade plants, water only when the top inch of the soil feeds dry to touch. Wait for the soil to dry out in between waterings.
