Monterey Sequestar Iron Supplement

In alkaline soils, iron often becomes 'locked' and unavailable for plants to absorb, leading to yellowing leaves. This product uses EDDHA chelated iron, a specific formulation designed to remain stable and absorbable even in high-pH environments where standard iron supplements fail.

This product is water-soluble, meaning you mix the granules with water according to the label instructions. Once dissolved, you can apply it as a soil drench around the base of your plants for direct root uptake.

If the yellowing is caused by iron chlorosis—a common condition where veins remain green while the leaf tissue turns yellow—this supplement is an effective remedy. However, if the yellowing is caused by overwatering, pests, or other nutrient deficiencies, this product will not solve the issue.

Yes, it is safe for a wide variety of vegetables, flowers, and trees. Because it is a targeted iron supplement, it is best used only when you have confirmed an iron deficiency rather than as a general-purpose fertilizer for every plant.

Because this is a fast-release formula, you should see improvements in foliage color relatively quickly, often within a few weeks of application. Keep in mind that severe deficiencies may require consistent monitoring and potentially follow-up applications.
