LawnStar Liquid Iron (32 OZ) for Plants - Multi-Purpose, Suitable for Lawn, Flowers, Shrubs, Trees - Treats Iron Deficiency, Root Damage & Color Distortion – EDTA-Free, American Made

What It Is

LawnStar Liquid Iron (32 OZ) is a liquid iron supplement for correcting chlorosis (yellowing), iron deficiency, and color distortion in lawns, flowers, shrubs, and trees. It’s not a mower part—it’s a soil treatment applied via sprayer or hose-end applicator to boost green color and plant health.

Fitment & Compatibility

• Not machine-specific: Works with any lawn or garden sprayer (handheld, backpack, or hose-end). No mower deck, model, or brand fitment needed.
• Check before buying: Ensure your soil pH is above 6.0 (iron is less available in alkaline soil). Test with a soil pH kit first—if pH is below 6.0, lime may be needed instead. For lawns, confirm grass type (cool-season vs warm-season; both work, but follow rate per 1,000 sq ft on label).
• OEM vs aftermarket: Not applicable—this is a standalone product, not a replacement part.

Key Things to Know

• Quality: EDTA-free formula reduces risk of leaf burn; American-made with chelated iron for faster uptake. 4.5 stars from 3,741 reviews indicates reliable results.
• Installation difficulty: Easy—mix with water and spray. No tools required. Apply when temps are below 85°F to avoid scorching.
• Common gotchas: Over-application can stain concrete or siding (blue-green residue). Rinse immediately. Not a fertilizer—it only corrects iron issues, not nitrogen or potassium deficiencies. Results visible in 3-7 days.
• Storage: Keep away from extreme heat; shelf life is typically 2 years if unopened.

Should You Buy It

Buy if your lawn or plants show yellowing between leaf veins (iron chlorosis) and you want a fast, safe fix without harsh chemicals. Skip if your soil pH is too low or you need a complete fertilizer—this is a spot treatment, not a full lawn program.
