Care guide
This species needs plenty of light and should be planted under 40% shade cloth, at most. It is rather sensitive to overwatering and should be planted in a gritty, fast draining soil mix that does not hold much water. A mix involving Akadama and pumice is ideal. Water well in summer, but keep completely dry in winter.
