Good drainage is essential to prevent root rot. Repot every 23 years in spring, refreshing the soil and giving roots a little more room. Choose a heavy pot to prevent tipping, as tall plants can become top-heavy. Feeding Feed lightly every 68 weeks during spring and summer with a diluted cactus or succulent fertiliser.
