How to Grow

Cultivation

Under glass, grow in a mix of 2 parts loam to 1 part each sharp sand and leaf mould, in full light with low humidity. Water sparingly from late summer to early winter and again in spring; additional fertiliser is not necessary. Conophytums need a dormancy period from late spring till midsummer and should be kept dry at this time

Propagation

Propagate by surface sowing seed at 20-25°C in late winter in moist, shady conditions. Gradually increase light and reduce humidity after germination. Separate and root complete bodies in late summer
