Know before you buy
This EDTA-chelated iron is most effective in acidic to neutral soils with a pH range of 4.0 to 7.0. If your soil pH is higher than 7.0, the iron may become locked up and unavailable to your plants.
Yes, because this fertilizer is 100% water-soluble and leaves no residue, it is well-suited for hydroponic applications. It provides a quick-release source of iron that is easily absorbed by plants in nutrient solutions.
You can typically expect to see visible greening and improved plant health within 7 to 14 days of application. The fast-acting formula is designed for rapid uptake to address iron deficiencies efficiently.
You can apply this powder as either a foliar spray or a soil drench. Both methods are effective, provided the solution is mixed thoroughly with water according to your specific plant's needs.
EDTA chelation acts as a protective shell for the iron, preventing it from reacting with other elements in the soil or water. This ensures the iron remains available for your plants to absorb rather than precipitating out and becoming useless.
This fertilizer is versatile and safe for lawns, vegetables, flowers, trees, shrubs, and houseplants. It is particularly beneficial for acid-loving plants that require consistent iron levels to maintain healthy chlorophyll production.
