Common Symptoms
General yellowing of leaves
Pale yellow discoloration spreads across the foliage, often affecting the oldest leaves first.
Signs to check
- Yellowing starts on the lowest (oldest) leaves and moves up the plant.
- Discoloration is even across the whole leaf, including the veins.
- Affected leaves stay flexible at first, then dry out and may fall.
- No spots, speckles, or powdery deposits are visible on the yellow areas.
Common causes
- Overwatering · Soil stays waterlogged, depriving roots of oxygen and causing rot.
- Nitrogen deficiency · Even yellowing affects the oldest leaves first.
- Insufficient light · The plant stretches, turns pale, and leans toward the window.
- Root rot · The plant wilts and turns yellow even though its soil stays moist.
- Iron deficiency · Young leaves turn yellow while their veins stay green.
- Soil pH too high · Soil conditions prevent the plant from accessing essential nutrients.
- Spider mites · Tiny arachnids that spin fine webs under leaves.
- Aphids · Small, pear-shaped insects, often clustered on new growth.
