TrueNute Tree Iron Chelate Combo Kit pairs our two most-requested tree iron chelates in one kit, so you're covered whether your soil runs neutral or alkaline.

  • 1x 16 oz TrueNute Tree Iron Chelate FeEDDHA 6% — stays soluble in alkaline soils up to pH 9.0, the gold standard for calcareous or hard-water conditions.
  • 1x 16 oz TrueNute Tree Iron Chelate DTPA 11% — fast-acting foliar spray formula, ideal for neutral-to-mildly-alkaline soils (pH 5.5–7.5) and rapid correction of active new growth.

Use the DTPA 11% for a fast foliar correction on active new growth, and the EDDHA 6% as a longer-lasting soil treatment in more alkaline conditions — giving your trees and bushes coverage across a wider pH range than either formula alone.
