Pros
  • Iron goes to work quickly as a liquid drench or spray
  • Odorless, so it is easy to apply near the house
  • Concentrate makes 32 oz go a long way
  • Works on turf, shrubs and trees
  • No nitrogen or phosphorus, so it won't push excess top growth
Cons
  • Supplies iron only, not a complete fertilizer
  • Easy to over-apply; iron stains concrete and siding
  • Foliar spraying needs care to avoid leaf burn in heat
  • Results depend on soil pH; high-pH soil ties up iron

Questions and answers

Is Bonide Liquid Iron a fertilizer?
It is sold as a fertilizer but has an NPK ratio of 0-0-0. Its only nutrient is iron, so it corrects iron deficiency rather than feeding nitrogen, phosphorus or potassium.
How do I apply it?
Mix the concentrate with water and apply as a foliar spray or soil drench. Follow the label rates for lawns, shrubs and trees.
Will it fix yellow grass?
It helps when the yellowing comes from iron chlorosis. If the cause is drought, disease or nitrogen shortage, iron alone won't fix it.
Does it stain?
Iron solutions can stain concrete, siding and clothing. Rinse off spills promptly and keep spray off hard surfaces.
Is it organic?
No. Bonide lists it as non-organic.

The best new price is $20.50 at eBay as of November 6, 2026. Spring lawn-care season is when demand and prices usually rise.
