Introduction

Sempervivums, also known as houseleeks, are easy-to-grow succulents that are perfect for adding a touch of greenery to rock gardens, walls, gravel, and paving. They are also relatively easy to propagate, so you can quickly increase your stock of these versatile plants.

Materials You’ll Need

• Sempervivum plants
• Small pots
• Multi-purpose compost with horticultural grit added
• Pencil or dibber
• Water

Step 1: Splitting the Clump

• Gently turn the pot upside down and tap it on a bench to loosen the plants.
• Pull or snip the small rosettes (offsets) growing out of the main plant, leaving a short stem and maybe some roots.

Step 2: Preparing the Pots

• Fill small pots with a mixture of multi-purpose compost and horticultural grit.
• Use a pencil or dibber to make a small hole in the compost.

Step 3: Planting the Offsets

• Place the offset in the hole and gently firm it into the compost.
• Mulch with grit to help keep the soil moist and suppress weeds.

Step 4: Watering

• Water the plants after a couple of days, but avoid overwatering.

Tips for Success

• Use sharp, clean tools to avoid damaging the plants.
• Plant the offsets in well-drained soil.
• Keep the plants in a sunny spot.
• Water the plants regularly, but allow the soil to dry out between waterings.

Troubleshooting

• If the offsets are not rooting, they may not be getting enough water.
• If the offsets are rotting, they may be getting too much water.
• If the offsets are leggy, they may not be getting enough sunlight.

Long-Term Care

• Once the offsets have rooted, you can transplant them into their permanent location.
• Sempervivums are relatively low-maintenance plants, but they will benefit from occasional watering and fertilizing.

Additional Information

• Sempervivums are also known as houseleeks because they were traditionally planted on rooftops to protect against lightning strikes.
• Sempervivums are native to the mountains of Europe and Asia.
• There are over 400 different species of sempervivums, so you’re sure to find one that you love.

With a little care and attention, you can easily propagate sempervivums and enjoy these beautiful and versatile plants for years to come.
