Burro's Tail (Sedum morganianum)

Burro's Tail

Sedum morganianum
Care level: Easy

The plump, tightly overlapping leaves of burro's tail form thick trailing ropes that can grow several feet long over the years, resembling a donkey's tail hanging from its native cliffside habitats in Mexico and Honduras. Each leaf is covered in a delicate powdery coating called farina, which reflects sunlight and reduces water loss, but which also rubs off if the plant is handled or bumped, exposing the greener skin beneath.

Common mistake

Moving, repotting, or brushing against a burro's tail too often is a common way owners accidentally strip it bare, since the plump leaves detach at the slightest touch and rarely reattach once knocked loose.

Care by Season

Spring

Resume watering as soil fully dries and begin light feeding as trailing stems grow.

Summer

Water once soil is completely dry and give plenty of bright light, handling gently to avoid dropping leaves.

Autumn

Reduce watering frequency and stop feeding as growth slows.

Winter

Water sparingly, roughly once a month, and keep in a bright, cool but frost-free spot.

Growing & Maintenance

Soil and pot

A fast-draining succulent or cactus mix in a shallow pot or hanging basket with drainage holes.

Fertilising

Feed lightly once or twice during the growing season.

Propagation

From stem cuttings or from single fallen leaves, both of which root easily when laid on dry succulent mix.

Pests & Diseases

Common problems

Leaves dropping at the slightest touch

Most likely cause: Normal. The leaves are only loosely attached.
What to do: Find the plant a permanent spot and move it as little as possible.

Shrivelled, wrinkled leaves

Most likely cause: Thirst.
What to do: Water thoroughly with tepid water, then let the compost dry out fully.

Soft, translucent leaves and rotting stems

Most likely cause: Overwatering.
What to do: Stop watering, let the compost dry out completely and repot into fresh, fast-draining mix.

Stretched stems with gaps between the leaves

Most likely cause: Too little light.
What to do: Give it bright light with several hours of direct sun.

Pale, scorched leaves

Most likely cause: A sudden move into hot, direct sun.
What to do: Increase the sun exposure gradually.

Pests & Diseases

Mealybugs

Signs: White cottony fluff tucked between the closely packed leaves.
Treatment: Remove with an alcohol-soaked cotton swab, repeating until clear. Check the undersides of the leaves and the crevices where the leaf stem meets the main stalk.

Aphids

Signs: Small clustered insects near stem tips and new growth.
Treatment: Rinse gently with water and apply insecticidal soap if needed.

Root and stem rot

Signs: Mushy, discolored stems and leaves dropping easily from overwatering.
Treatment: Stop watering, let soil dry fully, and repot into dry, fast-draining mix.

FAQ

Why do the leaves on my burro's tail fall off so easily when I touch it?

This is a natural trait of the species, not a sign of poor health; the leaves are only loosely attached to the stem, which in the wild helps fallen leaves root and start new plants on the ground below.

Can I grow a new burro's tail plant from the leaves that fall off?

Yes, fallen leaves can be laid on top of dry succulent soil and will often sprout tiny roots and a new rosette within a few weeks, so dropped leaves aren't necessarily a loss.

Is burro's tail safe for cats and dogs?

Yes, burro's tail is not toxic to cats or dogs.

How often should I water a burro's tail?

Roughly every 2-3 weeks, once the compost has dried out completely, and about once a month in winter. The plump leaves store water.

Does a burro's tail flower?

Rarely as a houseplant. It is grown for its trailing stems of plump, overlapping leaves.

How cold can a burro's tail get?

It tolerates temperatures down to about 4°C. A bright, cool but frost-free spot suits it in winter.
