Care & Cultivation

Aloes grow well in wide variety of habitats, from rocky hill slopes to semi-deserts to the Cape’s fynbos region. They like full sun, well-drained compost-enriched sandy soil. Aloes can be propagated from seeds and cuttings, but be careful to not over water cuttings, as this may cause them to rot. Aloes also hybridise easily with other aloes flowering at the same time.
