Succulent sempervivums, or houseleeks, are easy to grow and propagate as long as they're in full sun and well-drained soil.

In older plants, the bright rosettes of leaves will suddenly erupt into flower and die, but younger rosettes around them soon fill the space.

Propagating from these offsets allows you to fill areas of rock gardens, walls, gravel and paving.

Follow the easy steps in this guide to propagate your sempervivums.

Splitting a clump of sempervivums

Cup your hand over the plants and turn the pot upside down. Tap the rim on a bench and knock the plants gently out of the pot.

Separating individual sempervivums

The small rosettes growing out of the main plant can be pulled or snipped off, leaving a short stem and maybe some roots.

Potting up young sempervivum plants

Plant the offsets into small pots using a dibber to firm them into a gritty compost. Mulch with grit and water after a couple of days.
