Jade plants grow small and bush-like and spot small, attractive flowers in a variety of colors, making them ideal potted plants. However, these succulents aren't as hardy as some of their relatives. If their specific cultural needs are not met, jade plants can develop a number of problems, including rot. If your jade plants are rotting, first identify the cause of the problem. Otherwise, the jade plant will continue to rot even when planted in its new location.
Create a soil mixture that is one part potting soil, one part coarse sand and 1 cup bone meal.
Carefully remove the jade plant from its current pot.
Prune away all of the rotting plant tissue with a pair of disinfected pruning shears. When you prune, make the cut about 1/4 inch into the healthy tissue to make sure all of the disease is pruned away.
Rinse the soil away from the jade plant's roots. Check to see if any of them are darker in color, water-logged, dead or rotting. Prune these roots away. Again, prune 1/4 inch into the healthy root tissue.
Add enough of your soil mixture to the new pot so that the top of the jade plant's root ball sits near the top of the pot when set on top of the soil.
Place the jade plant in the pot carefully. Take care not to bend or break any of the roots. Finish filling the pot so that no more than 1 inch of potting soil covers the top of the jade plant's root ball.
Water the plant so that the soil is moist.
