The Andersons PGF Complete 16-4-8 Review

★★★★★ 4.8/5 editor rating

The lawn-forum favorite: fine-particle balanced feeding with humic acid — twice the granules per square foot of big-box bags.

Our Verdict

The enthusiast's pick, especially on warm-season lawns. Tiny particles spread with clinic-level evenness, the 16-4-8 ratio plus humics feeds both plant and soil, and results consistently look more uniform than the cheaper bags. It costs more per pound of nitrogen — the finish justifies it.

✅ Pros

  • Fine particles = extremely even coverage, no speckled feeding
  • Balanced NPK with slow-release nitrogen and micronutrients
  • Humic acid improves nutrient uptake in poor soils
  • The most consistently recommended fertilizer in lawn-care communities

⚠️ Cons

  • Higher cost per pound of nitrogen than big-box bags
  • Contains phosphorus — restricted for routine use in some states
  • Small bags — large lawns need several
