🌱 Benefits
Iron Chelate (6% Fe)

- Restores deep green colour in new growth
- For soil application, or on its own as a leaf spray
Humic Acid
- Holds onto nutrients such as calcium, magnesium and iron
- May help roots take up more of the nutrients you apply
- Works best in poor, sandy or stressed soil
- A soil conditioner, so keep up your normal feeding
💧 Quick Use

⭐ Why Use Them Together
The iron chelate fixes the iron shortage, and the humic acid backs it up. In a Spanish trial on lemon trees, adding humic substances to an iron chelate improved iron uptake compared with the chelate alone. Need more of one product? See the separate guides for Humic Acid and Iron Chelate 6%.
