Yellow leaves
Why are my Gerbera daisy's leaves turning yellow?Gerbera jamesonii
Yellowing is the most common distress signal a Gerbera daisy sends, and it almost always traces back to watering. On this plant it tends to show up as yellowing leaves and mushy crown — here's how to read which cause is yours.
Thirst (underwatering). Water thoroughly — every 5 to 7 days in summer is the usual pace for a Gerbera daisy — then settle into feeling the soil before every watering rather than watering on a fixed day.

What's causing it
Thirst (underwatering)
How to tell: The soil is bone dry, and the yellowing arrives alongside wilting leaves rather than soft, mushy growth.
The fix: Water thoroughly — every 5 to 7 days in summer is the usual pace for a Gerbera daisy — then settle into feeling the soil before every watering rather than watering on a fixed day.
Too little light
How to tell: The yellowing comes with pale, stretched new growth leaning toward the nearest window — Gerbera daisy 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.
Overwatering & early root rot
How to tell: The soil is still wet days after watering, the lower and oldest leaves yellow first, and the stem base may feel soft — often showing as yellowing leaves. This is the single most common cause on a Gerbera daisy.
The fix: Stop watering. Let the top 2 cm of soil feel dry completely, make sure the pot can actually drain, and only water again once it's dry. If the base is mushy or smells sour, unpot it and trim any brown, soft roots before repotting in fresh mix.
Hungry (nutrient shortfall)
How to tell: Older leaves fade to an even pale yellow and growth has clearly slowed — on a plant that likes 50-60% humidity and regular water, this shows up after many months in the same tired mix once feeding has lapsed.
The fix: Feed with a balanced, diluted liquid fertiliser through the growing season, and refresh the top layer or repot if it's been over a year.
Simple old age
How to tell: A single bottom leaf slowly yellows while the rest of the plant looks healthy and is pushing new growth.
The fix: Nothing is wrong — snip the spent leaf off and carry on. Plants retire their oldest leaves.

Check the mix regularly so it never goes bone dry for long, keep humidity up, and give it bright, indirect light.
Common questions
Should I cut off the yellow leaves on my Gerbera daisy?
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.
Will yellow leaves on a Gerbera daisy turn green again?
No. A fully yellowed leaf is spent. The goal is to stop NEW leaves from yellowing by correcting the cause — usually easing off the watering.
