These care conditions are most relevant to yellow leaves in Apple Tree. Check each one as a potential cause.
Symptoms to look for in Apple Tree
Yellowing between the leaf veins while the veins themselves stay green, or overall yellowing starting on older leaves lower in the canopy.
Common causes in Apple Tree
Yellowing between green veins usually points to iron or nutrient deficiency, especially in alkaline soils, while overall yellowing on older leaves often signals a balanced NPK feed is overdue.
How to diagnose yellow leaves in Apple Tree
Check soil moisture first. Wet soil + yellow lower leaves = overwatering. Dry soil = underwatering. Yellowing between veins = nutrient deficiency.
How to treat yellow leaves in Apple Tree
Apply a balanced fertiliser in spring if general yellowing is present, or a chelated iron treatment if the yellowing follows the between-vein pattern typical of iron deficiency.
Preventing yellow leaves in Apple Tree
Feed with balanced NPK in spring and switch to a potassium-rich feed once fruiting begins, and test soil pH periodically since apple trees prefer pH 6.0–7.0.
