常见问题
How big is an acre?
An acre is 43,560 square feet, roughly the size of a football field minus the end zones (about 90% of one).
How much seed do I need for my yard?
Grass seed coverage varies by type: 2-4 lbs per 1,000 sq ft for new lawns, 1-2 lbs for overseeding. Check the seed bag for specific rates.
What if my yard is not rectangular?
Break irregular shapes into rectangles and triangles, calculate each area separately, and add them together.
