Water your Burro's Tail about every 16 days. Always check that the top inch of soil is dry first — when in doubt, wait.

🩺 What's wrong with my Burro's Tail?

What is a burro’s tail?

Burro’s tail (Sedum morganianum), also called donkey’s tail or lamb’s tail, is a trailing succulent from Mexico that produces long, rope-like stems densely covered in overlapping, bead-shaped leaves of silvery blue-green. In a hanging basket with strong light, the stems can trail 1–3 feet, creating a lush curtain of colour. It’s one of the most visually dramatic succulents you can grow indoors — and it’s fully pet-safe.

How much light does a burro’s tail need?

A lot — this is a sun-lover. Burro’s tail needs at least 4–6 hours of bright direct or very bright indirect light from a south- or west-facing window. Good light is what keeps the stems densely packed with leaves in their characteristic tight bead pattern. In lower light the stems etiolate — they stretch out and the leaves space apart, losing the compact look entirely.

How often should you water a burro’s tail?

Water every 2–3 weeks in the growing season, letting the soil dry out completely between waterings. In winter, the plant goes semi-dormant — reduce to once a month or less. Use the “soak and dry” method: drench the pot thoroughly, then wait until the mix is bone dry before watering again. Overwatering is the primary killer of this plant; mushy stems or leaf bases mean rot has started.

Why do the leaves keep falling off?

Leaf drop is the most common complaint about burro’s tail, and the cause is almost always handling. The leaves are naturally loosely attached — the plant reproduces vegetatively from fallen leaves in the wild. Handle the pot as infrequently as possible, pick a permanent spot early, and be gentle. On the bright side, every fallen leaf is a free propagule: lay it on dry succulent mix and small plantlets will sprout from the base.

Why is my burro’s tail getting leggy?

Stretched, sparse stems with widely spaced leaves are the tell-tale sign of etiolation — the plant is not getting enough light and is reaching toward any available source. Move it to your brightest window with direct sun immediately. The stretched stems won’t compact back on their own, but new growth in good light will be dense again. Cut the leggy stems back and propagate the cuttings — they root readily in dry succulent mix.

Is burro’s tail safe for pets?

Yes — the ASPCA lists burro’s tail as non-toxic to cats, dogs, and horses. It is one of the few showstopping trailing succulents that is completely safe in a home with pets.

Frequently asked questions

How often should I water a burro's tail?

About every 2–3 weeks in the growing season, letting the soil dry completely first. In winter, when the plant is semi-dormant, cut back to once a month or less. Burro's tail stores water in its leaves and is far more likely to rot from overwatering than to die of thirst.

Why do burro's tail leaves fall off so easily?

The leaves are naturally fragile and attach loosely — this is a feature, not a fault. The plant spreads via fallen leaves in the wild. Handle it as little as possible and choose a permanent spot. The dropped leaves can be propagated by laying them on dry succulent mix.

Why is my burro's tail getting leggy and sparse?

Leggy stems with widely spaced leaves are etiolation caused by too little light. Move the plant to your brightest window — ideally with direct sun for several hours a day. The stretched portion won't fill back in; trim it and propagate the cuttings.

Is burro's tail safe for cats and dogs?

Yes — the ASPCA lists burro's tail (Sedum morganianum) as non-toxic to cats, dogs, and horses. It's a great choice for pet-friendly homes that want a dramatic hanging succulent.
