How to grow hens and chicks
Overview
Hens and chicks (Sempervivum tectorum) is a hardy rosette succulent grown for its neat, clump-forming foliage and cold tolerance. It thrives in full sun with sharp drainage and is ideal for filling gaps in rockeries, containers, or dry garden beds.
Varieties
- Sempervivum tectorum 'Green' — Classic green rosette with red tips, the most common form in Australian nurseries.
- Sempervivum tectorum 'Purple' — Deep purple-bronze rosettes that hold colour well in full sun.
Soil Preparation
Prefers a neutral to slightly alkaline pH (6.5–7.5) in a very gritty, free-draining mix. Add coarse sand, pumice, or crushed gravel to heavy clay. Avoid organic-rich compost that holds moisture.
Growing Guide
Plant in full sun with free-draining soil or gravel mix; avoid rich, moisture-retentive loam. Space offsets 15–20 cm apart to allow rosettes to spread. Water sparingly after establishment—overwatering causes rot. In cool or temperate zones, plant in raised beds or gritty pockets to ensure winter drainage.
Care
Feed lightly in spring with a balanced, low-nitrogen fertiliser (e.g., half-strength liquid feed). Remove spent rosettes after flowering to maintain vigour. Divide offsets every 2–3 years to prevent overcrowding and keep plants compact.
Companion Planting
Pairs well with other low-water succulents like Echeveria, Sedum, and small Aloes. Avoid planting near moisture-loving ferns or leafy perennials that will keep the soil damp.
Common Pests & Risks
Aphids can cluster on new rosettes; blast off with water or use a dilute neem oil spray. Crown rot from poor drainage or overwatering is the main disease—remove affected rosettes immediately and improve soil drainage.
Troubleshooting
Rosette turning mushy: overwatering or poor drainage—reduce water and improve soil. Leaves pale and stretched: too little light—move to full sun. Brown leaf tips: sunburn in extreme heat—provide light afternoon shade in hot zones. Offsets not rooting: detached too early or planted too deep—wait until chick has its own roots, plant shallow.
