Yellow leaves
Why are my Donkey's tail's leaves turning yellow?Sedum morganianum
Yellowing is the most common distress signal a Donkey's tail sends, and it almost always traces back to watering. On this plant it tends to show up as mushy translucent leaves and leaves shedding easily — here's how to read which cause is yours.
Overwatering & rot at the base. Stop watering completely. Let the soil has dried out completely before you even think about the next one, and check the pot actually drains — if the base is soft or smells sour, unpot it, cut away any mushy tissue, and repot in fresh, fast-draining mix.

What's causing it
Overwatering & rot at the base
How to tell: The soil stays wet for days, and the rot starts low — a soft, discoloured patch at the base or crown rather than one particular old leaf, often paired with mushy translucent leaves. This is the single most common cause on a Donkey's tail.
The fix: Stop watering completely. Let the soil has dried out completely before you even think about the next one, and check the pot actually drains — if the base is soft or smells sour, unpot it, cut away any mushy tissue, and repot in fresh, fast-draining mix.
Too little light
How to tell: The yellowing comes with pale, stretched new growth leaning toward the nearest window — Donkey's tail is bright / direct light and won't hold its colour much dimmer than 10,000 - 50,000 lux.
The fix: Move it to a brighter spot within its bright / direct light range, but keep it out of harsh midday sun, which scorches.
Thirst (underwatering)
How to tell: The soil is bone dry, and the yellowing arrives alongside shriveled beads rather than soft, mushy growth.
The fix: Water thoroughly — every 14 to 21 days in summer is the usual pace for a Donkey's tail — then settle into feeling the soil before every watering rather than watering on a fixed day.
Hungry — but rarely the real culprit
How to tell: Donkey's tail grows slowly and needs very little feeding, so a uniform pale-yellow fade after many months without any is possible, but check watering and light first — those are far more common on this plant.
The fix: Feed a cactus/succulent-formula fertiliser diluted to half strength, once or twice in the growing season only — overfeeding a slow grower like this does more harm than skipping it.
Simple old age
How to tell: An older, outer leaf near the base slowly yellows on its own while the centre keeps producing healthy new growth — normal turnover on a Donkey's tail, not a symptom.
The fix: Nothing is wrong — snip the spent leaf off cleanly at its base and carry on.

Let it dry out fully between waterings, never let it sit in a saucer of water, and keep it in bright light — root rot, not thirst, is the real risk on this plant.
Common questions
Should I cut off the yellow leaves on my Donkey's tail?
Once a leaf has gone fully yellow it won't turn green again, so it's fine to snip it at the base — it lets the plant put energy into healthy growth. Don't strip lots at once, though; if many are yellowing, fix the cause first.
Why does my Donkey's tail keep getting yellow leaves even though I barely water it?
A Donkey's tail that rots doesn't need much water to suffer — one soggy spell without full drying between waterings is enough to start it. Check the pot actually drains and that it isn't sitting in a saucer of water; that's usually the real cause, not the frequency.
