Blueberry care requirements
These care conditions are most relevant to yellow leaves in Blueberry. Check each one as a potential cause.
Symptoms to look for in Blueberry
Yellowing between the leaf veins while the veins themselves remain green, often starting on younger leaves at the shoot tips.
Common causes in Blueberry
This is classic iron chlorosis, caused by soil that isn't acidic enough for blueberries to absorb iron properly — even iron-rich soil becomes unavailable to the plant if the pH rises above the 4.5–5.5 range blueberries need.
How to diagnose yellow leaves in Blueberry
Check soil moisture first. Wet soil + yellow lower leaves = overwatering. Dry soil = underwatering. Yellowing between veins = nutrient deficiency.
How to treat yellow leaves in Blueberry
Test soil pH and lower it with sulphur if needed, and apply a chelated iron treatment for a quicker visual improvement while the soil pH adjusts over time.
Preventing yellow leaves in Blueberry
Maintain soil pH between 4.5 and 5.5 with regular ericaceous fertiliser applications, and water with rainwater or acidified water since tap water is often alkaline.
