Yellow lower leaves and a soft, mushy stem base indicate overwatering and the start of root or stem rot.

Leaves droop and curl, and lower leaves may yellow and drop when the plant has gone too long without water.

Growth and water needs slow noticeably in low winter light - let the top few centimeters of soil dry out before watering again.

Because of its toxicity, keep this one well out of reach of curious pets and small children, and wash hands after handling cut stems.
