How to care for Hens and Chicks
Sempervivum tectorum
Hens and chicks are alpine rosettes built to survive on poor, gritty soil and full sun with barely any water, and unlike most succulents they are fully frost-hardy outdoors. Each "hen" pumps out a ring of "chick" offsets that root themselves into a spreading mat. Sit it in the brightest, sharpest-draining spot you have and mostly leave it alone.
Care at a glance
- Light
- Full sun outdoors, brightest window indoorsSun keeps the rosettes tight and colourful; in shade they grow loose, green, and floppy. They are happiest grown outside.
- Water
- Very little — only in prolonged droughtOutdoors, rainfall is usually enough. For pots, water only when bone dry, roughly monthly in summer and not at all in a cold winter.
- Soil
- Lean, gritty, sharply drained soilPoor, stony soil or a gritty cactus mix; rich, damp soil makes them soft and prone to rot.
- Humidity
- Open-air or dry indoor conditions
- Temperature
- Frost-hardy, roughly to −20 °C (−4 °F)One of the few cold-hardy succulents — it overwinters outdoors in most temperate gardens.
- Difficulty
- EasyAbout as low-maintenance as a plant gets if grown lean, bright, and dry.
- Pets
- Non-toxic to petsNot listed on the ASPCA toxic plant list and has no known toxic principle; widely regarded as non-toxic to cats and dogs.
Where it comes from
Propagation
Hens and chicks propagate themselves — the parent rosette (the "hen") sends out short stems tipped with miniature rosettes (the "chicks") that often root where they touch the soil. To multiply deliberately, detach a chick once it has a few roots, or simply lift and replant the rooted offsets into gritty soil; they establish almost immediately.
A hen is monocarpic: after a few years it may push up a curious flower stalk, set seed, and then die — but by then it is ringed by chicks ready to take its place, so the colony carries on indefinitely. Pinch out the flower stalk if you prefer to keep the clump uniform.
Common problems
- Rosettes stretching tall, soft, and pale green
Likely cause: Too little light, indoors or in a shady spot.
Fix: Move it into full sun — ideally outdoors — and the new rosettes will tighten and regain their colour.
- Centre rosette rotting or turning to mush
Likely cause: Wet soil, especially over a damp winter, rotting the crown.
Fix: Improve drainage, keep it dry in winter, and remove the rotten rosette; the surrounding chicks usually survive.
- A rosette sending up a tall stalk then dying
Likely cause: Normal monocarpic flowering — that hen blooms once and dies after setting seed.
Fix: No action needed; the chicks it left behind fill the gap. Remove the spent rosette once it dries up.
Frequently asked questions
Can hens and chicks survive winter outside?
Yes — Sempervivum is one of the few succulents that is genuinely frost-hardy, tolerating temperatures well below freezing in most temperate gardens. The main winter risk is not cold but soggy soil, so plant it somewhere very free-draining.
Why is one of my hens growing a tall stalk?
That rosette is flowering. Sempervivum is monocarpic, so a hen blooms just once on a tall stalk and then dies after setting seed. It is normal; the surrounding chicks live on and fill the space it leaves.
What is the difference between hens and chicks and echeveria?
They look similar but are different plants: hens and chicks (Sempervivum) are cold-hardy European alpines that survive frost outdoors, while echeveria are tender Mexican succulents that must be kept frost-free. Both form rosettes and offsets.
Do hens and chicks need fertiliser?
Almost none. They evolved on poor, stony ground, and rich feeding makes them grow soft and lose their compact, colourful form. At most, a very weak feed once in the growing season is plenty.
