iron deficiency on Date Palm
Quick answer
If your Date Palm has iron deficiency, the most likely cause is: Iron deficiency (interveinal chlorosis) and zinc deficiency (small leaves, rosetting) are common in date palms grown in calcareous soils with pH 7.5-8.5. High bicarbonate levels lock out iron, while zinc becomes insoluble. These deficiencies reduce photosynthesis and fruit quality.
Start here:
- 1. 1. For iron deficiency: Apply Fe-EDDHA chelate at 5-10g per 100L water as foliar spray
- 2. 2. For zinc deficiency: Apply Zn-EDTA at 3-5g per 100L water or zinc sulfate at 0.5% concentration
Why Date Palm gets iron deficiency
Iron deficiency (interveinal chlorosis) and zinc deficiency (small leaves, rosetting) are common in date palms grown in calcareous soils with pH 7.5-8.5. High bicarbonate levels lock out iron, while zinc becomes insoluble. These deficiencies reduce photosynthesis and fruit quality.

Keep iron deficiency off this Date Palm
Apply micronutrient foliar sprays in early spring before temperatures rise. Use chelated forms (Fe-EDDHA, Zn-EDTA) for better uptake in high pH soils. Apply 2-3 sprays at 3-week intervals.
