How this shows up on a Flamingo flower
The plant yellows from below and the pot stays heavy
A sour smell from the compost is common on a flamingo flower, and the lowest leaves on each stem come away when pulled. The surface may look dry while everything beneath it is not.
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 a Flamingo flower
Most likely too little water
Ranked higher because Flamingo flower's recorded problems point this way.
- Moist but well-drained RHS · read 13 September 2026
Why: Soil dry two inches down, under lower leaves that are yellowing or leaves that are falling, is a flamingo flower shedding what it cannot support.
What to try:
- Water until it runs from the drainage hole, then let the pot drain.Useful: pot with drainage holes
- If the water runs straight through a shrunken rootball, stand the pot in water for twenty minutes so the compost can take it up.
What would settle it: Water it thoroughly and look again the same evening. A thirsty plant firms up fast. One that does not has a root problem rather than a water problem.

- Loam; pH Acid 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 flamingo flower 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 too little water
Ranked higher because Flamingo flower's recorded problems point this way.

Why: Soil dry two inches down leaves the roots nothing to send up, and the leaf edges are the last tissue in line.
What to try:
- Water thoroughly, until it runs from the drainage hole.Useful: pot with drainage holes
- Check the soil with a finger every few days rather than watering on a fixed day.Useful: moisture meter
What would settle it: Water it thoroughly and watch the next new leaves. If they come in with clean edges under steadier watering, the edges were thirst.
Less likely for a Flamingo flower, still possible
- Most likely cold
- Most likely not enough light
- Most likely short of nutrients
- Most likely a build-up of salts in the soil
- 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
- Light and feeding are both plausible, and this does not separate them
- 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.
