Iron chelate

The fast fix for yellow leaves with green veins (iron chlorosis).

What it's for: Fe-EDDHA iron chelate (ortho-ortho isomer), 6% soluble iron. Prevents and corrects iron deficiency in vegetables, trees and ornamentals. Iron is essential to chlorophyll synthesis.

Best for: Citrus, fruit trees, hydrangeas, camellias and anything that yellows on chalky soil.

When to apply: Spring, summer and autumn, or as soon as chlorosis appears.

How often: 2 to 3 times per year.

Dose: 2.5 g/l.

How to apply: Dilute in the watering.

Worth knowing: The ortho-ortho isomer stays stable between pH 4 and 12 — it works where cheap chelates fail, which is on chalky soil. Will not clog drip irrigation.
