Yellow leaves with green veins

Signs to check

• Yellowing is confined to the areas between veins, which form a clearly visible green pattern against the yellow background.
• The symptom often appears first either on the youngest leaves (at the top of the plant) or the oldest leaves (at the bottom).
• The boundary between yellow tissue and green veins is sharp, without a gradual color transition.
• At first, affected foliage has no dead patches, powdery deposits, or physical distortion.
• Over time, the yellow may deepen, and in severe cases the veins may eventually lose their green color.

Common causes

1. Iron deficiency · Young leaves turn yellow while their veins stay green.
2. Soil pH too high · Soil conditions prevent the plant from accessing essential nutrients.
3. Overwatering · Soil stays waterlogged, depriving roots of oxygen and causing rot.
