Others have successfully planted Kalanchoe Delagoensis "Chandelier Plant" in the same container as other succulents. But if your String of Pearls have been in the same potting mix for over a year, nutrients in the soil may have already seeped out from all the watering. I am guilty of paying too much attention to String of Pearls and neglecting this other important plant. Sunburn and sun damage are two of the most common causes String of Bananas turning brown. String of Pearls that are younger and less well-established need more water than mature plants.
