Iron for Hardwoods & Fruit Trees

Yellow leaves aren't a mystery. They're an iron deficiency problem, and fast-acting foliar iron fixes it fastest.

Most tree iron deficiency isn't a lack of iron in the soil — it's iron your tree can't reach. TrueNute pairs a foliar spray for rapid green-up with a soil-drench chelate that locks in long-term correction, so your trees green up fast and stay that way.

See the two-part system Why pH matters

Iron availability by soil pH

Standard chelates fail as soil turns alkaline. EDDHA holds on where others quit.
pH 5 pH 6.5 pH 8 pH 9.5 EDDHA 6% DTPA / EDTA / sulfate
Stays available past pH 9 Locks out above pH 7.5
The Two-Part System

Spray the leaves first. Drench the roots for the long haul.

Built around the same chemistry True Aquaponics uses to correct iron lockout in high-pH systems — scaled for hardwoods, orchards, and lawn-adjacent plantings.

Part One · Foliar Spray

TrueNute Tree Iron Chelate FeDTPA 11%

Absorbed directly through the leaf, DTPA delivers a fast green-up in days — see color change on new growth before the root-zone correction even kicks in.

For fast visible results
Part Two · Soil Drench

TrueNute Tree Iron Chelate FeEDDHA 6%

Applied at the root zone, EDDHA stays chelated and plant-available even in alkaline, high-pH soils where ordinary iron products fail within days — the long-term fix once DTPA gets you moving.

For long-term correction
