Lawn & Seed
The lawn & seed math and money: grass seed and lime pounds from your lawn area and the labeled seeding rate, sod rolls and pallets (with waste), fertilizer pounds of product from the nitrogen rate and the %N on the bag, a lawn-area estimator that adds up rectangles, and artificial-turf and lawn-care cost from the prices you enter. Coverage varies by product — buy a little extra and confirm it on the bag.
Planning estimate: this is a planning estimate. Coverage varies by product (bag size, compaction, waste, slope and how tightly you pack). Buy about 5–10% extra and confirm the coverage printed on the product before you order.
