Cultivation: E. bristolli is relatively easy to grow and very attractive. Rot easily it is sensitive to overwatering (rot prone), so perfect soil drainage is a must. It prefer a neutral to slightly acidic compost with plenty of extra grit.  Best if watered with rain water and given an occasional tonic of sequestrated iron. In the summer they need an airy location in bright sun; well watered when it's hot. To achieve the best spine colours give these plants lots of sun. In the winter light, cool, and absolutely dry conditions. Very cold resistant  above approx -12C or less for short periods of time. In mild climate they grow well when planted freely outside in well-drained soil.

Propagation: Seeds
