How this shows up on a Bird of paradise
Faded, yellow-white areas on the sunny side of the plant
The damage on the bird of paradise faces one way. Turn the pot round and the other side is clean.
Even a plant described as full sun, partial shade can take more through glass than it would outdoors, because glass removes the breeze that carried the heat away.
Telling it apart: The edge of the damage. Scorch has a sharp boundary; rot and infection have a soft, spreading one.
RHS · read 13 September 2026Yellow, limp leaves at the base
The lowest leaves of the bird of paradise go yellow and translucent at the stalk and drop with a light pull, while the compost stays wet.
Soil described as moist but well-drained or well-drained is a drainage instruction as much as a watering one. Compost that stays saturated suffocates the fine roots that do the drinking.
Telling it apart: The soil, not the leaf. Wet compost under yellowing leaves points one way and dry compost the other, and the leaves alone will not tell you which.
RHS · read 13 September 2026Possible causes, likeliest first for a Bird of paradise
Most likely not enough light
Ranked higher because Bird of paradise's recorded problems point this way.
- Full sun, Partial shade RHS · read 13 September 2026
Why: Far from a bright window, a bird of paradise 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; a bird of paradise that is barely growing uses little.
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 Bird of paradise's recorded problems point this way.
- Moist but well-drained or Well-drained RHS · read 13 September 2026
- Chalk, Loam, Sand; pH Acid or Alkaline or Neutral RHS · read 13 September 2026
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: pot with drainage holes
What would settle it: Lift the bird of paradise out of its pot. Healthy roots are firm and pale; roots that have been wet too long are brown, soft and smell sour.
Most likely cold
Ranked higher for Bird of paradise because of what its sources say.
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.
- H1B — 10–15°C RHS · read 13 September 2026
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 bird of paradise.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the bird of paradise 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.
Less likely for a Bird of paradise, still possible
- Most likely too little water
- Most likely short of nutrients
- Most likely 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
- Possibly root rot, in a pot that has stopped draining
- Probably too much water, but this is not settled
- Probably too much water
- Possibly too much direct sun
- Possibly too much direct sun, or feeding
- This may be ordinary leaf loss
- Possibly dry air
- The answers do not point at one cause

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.
