Planting Outdoors

From Late Winter TO Early Spring

Plant container grown plants in deep fertile, well-drained soil in a sunny site, in late winter/early spring. Surrounding the corms and root in a mix of coarse bark, shingle and sharp sand when planting will help to prevent it rotting in a wet climate.

 

Propagation by seed or offsets

From Late Summer TO Late Autumn

Propagate by seed, sowing them in containers in a cold frame in autumn. Offsets may be removed in late summer
