Ferti-Maxx

Ferti-Maxx Iron Maxx is a 5% iron supplement formulated not to stain concrete, stone or equipment — the usual complaint with cheaper iron sprays along walks and pool decks.
Our Ferti-Maxx range is Iron Maxx in 1 gallon, applied as a foliar or soil spray when turf is pale from iron deficiency rather than a missing nitrogen application.
