Per-Acre Quick Reference

Based on your presets

The table below auto-computes lbs/acre and bags/acre from each product’s bag weight and “new lawn” coverage per bag. Overseed assumes ~½ rate (≈double coverage).

Product	Bag (lb)	Coverage / Bag (New)	New Lawn — lbs/acre	New Lawn — bags/acre	Overseed — lbs/acre	Overseed — bags/acre

Example check (Sungold TWCA Tall Fescue (raw)): 43,560 ÷ 3,500 = 12.44 bags/acre × 25 lb = 311 lb → round ≈ 310 lb.
