Iron Deficiency of Peach
Return to Abiotic Disorders
Iron deficiency results in bright yellow leaves while veins remain green. Symptoms are more severe on the youngest leaves. This deficiency is evident when soil pH is too high (7.3 and above) and iron is chemically bound in the soil, making it unavailable to the tree.

Management:
- Check soil pH and evaluate tree iron levels through laboratory foliar analysis.
- For a long term solution, lower soil pH with sulfur before planting.
- For established orchards, apply iron chelates to foliage or soil.
