Our take on the Ferric Sodium EDDHA

Ferric sodium EDDHA (FeNa-EDDHA) is a chelated iron fertilizer used to correct iron chlorosis in plants, especially in alkaline or calcareous soils where ordinary iron salts lock up. The chelate keeps iron available across a wide pH range, which is why it is a standard choice for citrus, ornamentals and other crops showing yellowing between green veins. This listing is a 100 g pack sold as a laboratory-grade chemical. At $395.00 at Molecular Depot as of November 6, 2026, it is the best of three new prices, but that figure reflects small-quantity lab supply pricing, not farm-scale fertilizer cost.

Best forCorrecting iron chlorosis in alkaline or calcareous soilCitrus, ornamentals and acid-loving plants showing interveinal yellowingSmall-scale or lab use where a 100 g quantity is enoughGrowers who need iron available across a wide pH range
Pros
  • Chelated iron stays available in alkaline soils where iron sulfate fails
  • Works across a broad pH range
  • Soluble and chemically stable in storage
  • Targeted treatment for iron deficiency rather than a general fertilizer
Cons
  • 100 g is a tiny quantity for garden or field use
  • $395.00 at Molecular Depot is lab-supply pricing, far above bulk agricultural EDDHA
  • No application rate or dilution guidance in the listing
  • Overdosing iron chelate can harm plants; dosing needs care

Questions and answers

Is ferric sodium EDDHA worth it at $395 for 100 g?
Only if you need a small, lab-grade quantity. The same compound as agricultural iron chelate sells in kilogram bags for a fraction of this per-gram price, so home gardeners should compare bulk fertilizer products first.
How is it different from iron sulfate?
Iron sulfate is cheap but its iron becomes unavailable in alkaline soil. EDDHA keeps iron chelated and plant-available up to high pH, which is why it is used for chlorosis in calcareous soils.
How do I apply it?
Agricultural EDDHA is usually dissolved in water and applied to the soil around the root zone, often before the growing season. This pack gives no rate, so follow label guidance for the concentration you buy.
Can I use it on any plant?
It suits most crops and ornamentals with iron deficiency, including citrus and acid-loving plants. It is not a substitute for fixing other causes of yellowing, such as overwatering or nitrogen shortage.
Is it the same as FeNa-EDDHA?
Yes. Ferric sodium EDDHA and FeNa-EDDHA are the same chelated iron compound.
Where is the Ferric Sodium EDDHA cheapest?
At Molecular Depot, for $395.00, as of our latest check.
Where can I buy the Ferric Sodium EDDHA?
3 stores we checked sell it, including Molecular Depot, Spectra Services, Blue Tiger Scientific.
