Citrus & Avocado Fertilizer 14-6-4 is a professional-grade, 100% water-soluble fertilizer formulated for citrus and avocado trees in the high-pH soils common across California, Arizona, and Texas. Its 14-6-4 NPK uses a triple nitrogen blend — ammoniacal, urea, and nitrate — for both immediate and sustained feeding, with the ammoniacal fraction creating a localized acidifying effect in the root zone.
Iron, zinc, manganese, and copper are EDTA-chelated to resist precipitation in alkaline soil, with boron and molybdenum included for complete nutrition. The formula also supplies 3% magnesium and 9% sulfur, and is chloride-free — suited to salt-sensitive avocado and citrus. It dissolves clean for drip, micro-sprinkler, and fertigation systems.
Apply to the root zone out toward the dripline and water in thoroughly, splitting the annual amount across several feedings from spring through fall. Keep product off the trunk; do not combine with calcium fertilizers in the same concentrated stock tank.
CDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.
