TrueNute Tree Iron Chelate Combo Kit — our higher-volume EDDHA option paired with a fast-acting foliar DTPA treatment, built for larger trees or more established alkaline soil conditions.

  • 1x 64 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. The 64 oz size covers more ground for larger trees, orchards, or ongoing seasonal treatment. The 64 oz size comes in a larger plastic bag.
  • 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 larger EDDHA 6% supply as your primary longer-term soil treatment in alkaline conditions.
