Know before you buy
EDDHA chelation is highly stable, meaning it keeps iron available to your plants across a wider range of soil pH levels. It is particularly effective in alkaline soils where other forms of iron might become locked up and unusable by the plant.
Yes, this formula is safe for vegetables, flowers, trees, shrubs, and houseplants. It is designed to treat iron deficiency, which typically manifests as yellowing leaves with green veins.
You can do both. Soil drenching is generally the most effective method for long-term correction of iron deficiency, while foliar feeding provides a faster, temporary boost to the foliage.
The concentrate is potent; mixing 1 teaspoon per gallon of water will yield approximately 42 ppm of iron. Always start with the recommended dosage to avoid over-application.
Because this is a quick-release, water-soluble formula, plants can absorb the iron rapidly. You should typically notice an improvement in foliage color within a week or two, depending on the severity of the deficiency.
