Wrinkled Jade Leaves: Underwatering
In nature, jade plants store water in their leaves, which allows the plants to survive dry periods. The leaves of a well-hydrated jade are plump, while thin, wrinkled jade leaves are a good sign that the plant needs water. Don’t go by appearance alone, however, and never water without feeling the potting mix first. Ideally, water only when the potting mix is dry nearly to the bottom of the container. If you’re not sure, stick a wooden skewer in the pot to test the moisture level.
Wrinkled Leaves on Jade: Overwatering
Underwatering is easy to fix, but a seriously overwatered jade plant may not survive. Often, a wrinkly jade plant with yellow leaves is an indication of overwatering. If the roots are beginning to rot, the plant may die if you don’t address the problem as soon as possible. You may be able to save a plant with root rot by repotting the jade in fresh potting soil. Slide the plant carefully from the pot and trim any brown, mushy leaves. Hopefully, some of the roots will still be healthy and white. Repot the jade in a clean pot, using a special potting mix for cactus and succulents. Regular potting mix doesn’t drain well enough for jade plants. Be sure the container has a drainage hole. Don’t assume a layer of gravel in the bottom of the pot will provide adequate drainage, because the gravel is likely to just trap water around the roots. Water the plant only when the soil is dry. Never allow the pot to stand in water, any water left in the drainage saucer should be poured out as soon as possible.
