Coffee plant leaves turning yellow: causes and what to do
17 results in the diagnosis tree begin with yellowing leaves, 7 of them marked likely when the answers fit. They are ordered here for Coffee plant (Coffea arabica), using what its sources say about soil moisture, light, soil, watering and feeding and 2 problems recorded for it.
Sources last read 14 September 2026.
Coffea arabica, also known as the Arabica coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is the dominant cultivar, representing about 60% of global production. Wikipedia, CC BY-SA 4.0
Native range: E. South Sudan, SW. Ethiopia, N. Kenya (Mt. Marsibit) (seasonally dry tropical). Also sold as Arabian Coffee, arabica coffee and coffee.

How this shows up on a Coffee plant
Pale dry areas across the upper leaves only
Upper surfaces lose colour while the undersides stay green, and nothing below the top of the canopy is touched.
Its source names partial shade, yet a leaf grown in lower light has thinner tissue than one grown in sun, and it scorches if moved into strong light in one step.
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 2026The older part of the canopy yellows while the potting mix stays soaked
The coffee plant yellows from the base up. Affected leaves bend rather than snap, and the pot is still heavy several days after watering.
Water held around the roots for days leaves them without air, and a root without air stops working within a week. Its source describes moist but well-drained soil for good reason.
Telling it apart: Lift it from the pot. Firm pale roots mean the water is not the problem; brown soft ones that smell sour mean it is.
RHS · read 13 September 2026Possible causes, likeliest first for a Coffee plant
Most likely too little water
Ranked higher because Coffee plant's recorded problems point this way.
- Pale dry areas across the upper leaves only RHS
Why: Soil dry two inches down, under lower leaves that are yellowing or leaves that are falling, is a coffee plant shedding what it cannot support.
What to try:
- Water until it runs from the drainage hole, then let the pot drain.Useful: moisture meter
- If the water runs straight through a shrunken rootball, stand the pot in water for twenty minutes so the potting mix can take it up.Useful: moisture meter
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.
Most likely not enough light
Ranked higher because Coffee plant's recorded problems point this way.
- Pale dry areas across the upper leaves only RHS
Why: Far from a bright window, a coffee 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; a coffee 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 Coffee plant's recorded problems point this way.
- The older part of the canopy yellows while the potting mix stays soaked 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 coffee 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 a Coffee plant, still possible
- Cold
- 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

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.
