How this shows up on an Urn plant
Buds that yellow and drop on a leafy plant
The urn plant sets buds normally, and they yellow at the stalk and drop before they colour.
A bud is the most expensive thing on the plant. Kept below the partial shade its source names, or moved while in bud, the urn plant abandons buds before it abandons leaves.
Telling it apart: What happened in the fortnight before the buds dropped. A move, a turned pot or a dry spell is the usual answer.
RHS · read 13 September 2026New leaves arrive smaller and paler than the ones below
An urn plant reaches. Stems extend between leaves, and the newest growth is the palest thing on the plant while older leaves hold their colour.
Placed below what its source describes, the plant prioritises reaching over building. Longer stems and smaller leaves are that choice made visible.
Telling it apart: Measure the gap between the newest two leaves against an older pair. Reaching is a change in spacing, not only in shade.
Clemson Extension · read 13 September 2026The plant yellows from below and the pot stays heavy
Yellow spreads upward through the urn plant a few leaves at a time, and the potting mix darkens and stays cold to the touch.
Roots sitting in water run out of oxygen, and the first sign above ground is the oldest leaves being given up. Its source describes moist but well-drained soil, which is air as much as water.
Telling it apart: Whether the drainage hole drips when the pot is tilted. Water still running out days later is the answer.
RHS · read 13 September 2026Possible causes, likeliest first for an Urn plant
Most likely cold
Ranked higher because Urn plant's recorded problems point this way.
Its RHS hardiness rating puts this plant's cold floor at 10°C or above, so a cold windowsill at night is a strong explanation.
- The plant yellows from below and the pot stays heavy RHS
Why: Soft, dark patches rather than crisp ones are damaged tissue rather than dried tissue.
What to try:
- Move it away from the glass at night, or keep the curtain on the room side of the urn plant.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the urn plant sits at night, and what the glass feels like at that hour. Damage that appeared after one cold night, on the side facing the window, is the pattern.
Most likely not enough light
Ranked higher because Urn plant's recorded problems point this way.
- Buds that yellow and drop on a leafy plant RHS
- The plant yellows from below and the pot stays heavy RHS
Why: Far from a bright window, an urn plant builds leaves it cannot afford.
What to try:
- Move it closer to the brightest window you have, over a week or two rather than in one step.Useful: grow light
- Water less while it is in low light; an urn plant that is barely growing uses little.Useful: moisture meter
What would settle it: Compare a new leaf with one from last year. Smaller and paler, with a longer gap below it, is the reaching pattern rather than a nutrient one.
Most likely too much water
Ranked higher because Urn plant's recorded problems point this way.
- The plant yellows from below and the pot stays heavy RHS
Why: Soil that is wet two inches down, under leaves that are yellowing from the bottom or falling, points at roots that cannot breathe.
What to try:
- Hold off watering until the top two inches of soil are dry, and check again with a finger rather than by the calendar.Useful: moisture meter
- Empty any water standing in the saucer or the outer pot within half an hour of watering.Useful: moisture meter
What would settle it: Lift the urn plant out of its pot. Healthy roots are firm and pale; roots that have been wet too long are brown, soft and smell sour.
Less likely for an Urn plant, still possible
- Too little water
- Short of nutrients
- A build-up of salts in the soil
- Light and feeding are both plausible, and this does not separate them
- Nutrients are an unlikely explanation here
- Root rot, in a pot that has stopped draining
- Too much water, but this is not settled
- Too much water
- Too much direct sun
- Too much direct sun, or feeding
- Ordinary leaf loss
- Dry air
- The answers do not point at one cause
Questions
- What usually causes yellowing leaves on an Urn plant?
- For Urn plant: cold, not enough light and too much water. Its RHS hardiness rating puts this plant's cold floor at 10°C or above, so a cold windowsill at night is a strong explanation.
- How can I tell which one it is on my Urn plant?
- Where is the yellowing? The lowest leaves, working upward; New growth at the top, while older leaves stay green; Between the veins, the veins themselves still green; At the leaf tips and edges, browning as it goes; Patchy, only on the side facing the window.
- What do Urn plant's sources say about its soil moisture?
- RHS: Moist but well-drained.
- What does this look like on an Urn plant?
- The urn plant sets buds normally, and they yellow at the stalk and drop before they colour. Telling it apart: What happened in the fortnight before the buds dropped. A move, a turned pot or a dry spell is the usual answer.

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
