How do I save my hens and chicks from root rot?

The 4 most likely causes

The cause of hens and chicks root rotusually narrows to one of the items below, ranked by how often we see each in Growli's diagnostic chats. Work down the list — most readers find their answer in the top two.

1. Root rot (Most likely)
   Root rot is what happens when overwatering or poor drainage goes uncorrected. The roots turn brown and slimy, the stem softens from the base up, and the plant can no longer move water to its leaves — so paradoxically it wilts even though the soil is soaking. Unpot hens and chicks now and inspect the roots; firm white roots stay, mushy brown ones get trimmed.
2. Overwatering or poor drainage (Likely)
   Hens and chicks stores water in its leaves and stems, so the roots stay turgid even after long dry spells. When you water on a fixed weekly schedule the soil never fully dries, the roots suffocate, and the lower leaves go yellow and squishy. Aim for water only when the soil is bone dry — every 3-4 weeks indoors.
3. No drainage hole or a too-dense potting mix (Likely)
   A pot without a working drainage hole — or a heavy, compacted mix that holds water like a sponge — rots roots even under a careful watering hand. Water needs to flow through the pot, not sit in it. Hens and chicks wants a free-draining mix and a pot that empties from the bottom within a minute of watering.
4. Fungus gnats (a wet-soil warning sign) (Possible)
   Small dark flies drifting up from the soil of hens and chicks are fungus gnats — their larvae live in constantly damp potting mix and nibble fine roots. The gnats themselves are a symptom: soil that stays wet enough to breed them is wet enough to rot roots. Let the top few centimetres dry out fully between waterings and the population collapses.

Why hens and chicks in particular

This is a plant of thin, gritty mountain screes and old roof tiles — its very name, tectorum, means 'of roofs' — so its fine roots demand air and sharp drainage and drown quickly in rich, water-holding compost. Left wet, the roots blacken and rot, the crown softens above them, and the rosette loosens and topples. An alpine built to endure drought has almost no tolerance for standing water, which is why free-draining, gritty soil and dry spells between waterings are its whole defence.

Normal turnover, or real trouble?

This is a shallow-rooted alpine, so healthy roots are fine, pale and surprisingly sparse — a rosette that seems only loosely anchored in grit is often perfectly sound, and freshly separated chicks may have barely any roots yet at all. That is normal. Rot looks unmistakably different: the roots turn brown-black, soft and slimy, they smell, and the damage travels up into a softening crown and a rosette that lifts away with almost no resistance.

How to diagnose in 60 seconds

Run these quick checks before you change anything — the right fix depends on what you find.

• Smell the soil at the drainage hole. Sour, swampy, or sulphurous = rot is active below the surface.
• Tip hens and chicks out of its pot and look at the roots: firm and pale is healthy; brown, soft or sour-smelling is rot, which is the real cause behind most of these symptoms.
• Is the plant wilting even though the soil is wet? That paradox — thirsty-looking in soaked soil — is the root-rot signature.
• Check the pot itself: is there a working drainage hole, and does water actually run out of it when you water?

The fix — step by step

The fix is drying and grit, never more water. Unpot the rosette, crumble away the wet compost, and trim any blackened, slimy roots back to pale firm tissue — or cut the clean rosette off above the rot if the roots are gone. Let it dry in the air for a day or two, then replant shallowly in a very free-draining, gritty medium and hold off watering for a week while fresh roots form.

This is the recovery sequence Growli walks users through for hens and chicks with root rot. Work through the steps in order; skipping ahead is the most common reason a plant fails to bounce back.

1. Unpot and wash the roots today. Root rot doesn't pause. Slide hens and chicks out of its pot, crumble away the wet soil, and rinse the rootball gently under lukewarm water so you can see what's left.
2. Cut every rotted root off. With scissors wiped in isopropyl alcohol, cut back to firm, pale tissue — brown, slimy, or hollow roots all go, even if that means removing most of the rootball. A few clean roots beat a potful of rot.
3. Repot into fresh, dry, free-draining mix. Use a clean pot with a real drainage hole — one size smaller if you removed a lot of roots — and a chunky mix (add perlite or bark). Old soil and an unwashed pot re-infect; bin the soil, bleach-rinse the pot.
4. Water once, then hold back. Water lightly to settle the mix, then wait until the top few centimetres are fully dry before watering again. The plant has fewer roots now — it drinks far less than before. No fertiliser until new growth appears.
5. Take an insurance cutting. If the rot was extensive, root a healthy stem cutting in water now. If the parent pulls through you have a bonus plant; if it doesn't, you haven't lost hens and chicks entirely.

When this can't be saved

Most cases of hens and chicks root rot are recoverable, but a few red flags point to a plant that has gone past the point of return. If you spot any of these, consider propagating a clean cutting and starting over.

• No firm, pale roots remain at all — with zero healthy roots to rebuild from, a stem cutting is the only realistic rescue.
• The rot has climbed above the soil line into the main stem or crown, which is soft and darkening from the base up.
• The soil smells foul and sewer-like — bacterial soft rot moves faster than fungal rot and is much harder to stop.

Prevention

For hens and chicks, the single biggest preventative is matching its native rhythm: water only when the soil is bone dry — every 3-4 weeks indoors, full sun or the brightest sill available, and a free-draining pot with a working drainage hole. Never let the pot stand in a saucer of drained water, add a third of perlite or bark to the mix at every repot, and make the finger test non-negotiable — rot is bred by watering the calendar instead of the soil. A yearly root check at repotting time catches trouble while it is still trimmable.
