Spring - early-mid · Planting

Divide when too large

The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.

Indoor temperature · Planting

Compost · Planting

Cactus compost for repotting

Use standard cactus compost. Top the soil with grit or granite chips to ensure perfect drainage around plant stem. Repot when the plant is dry and delay watering for 3 days after repotting.

You can also make own compost using 3 parts John Innes no. 2, 1 part horticultural grit, and 1 part horticultural grade perlite or pumice. There are many 'recipes' available and opinions vary widely - consult specialist literature or websites.

Position in a sunny spot, eg windowsill
