FAQ

How much grass seed do I need?

Pounds of seed = lawn area ÷ 1,000 × seeding rate (pounds per 1,000 square feet). Bags = pounds ÷ bag weight, rounded up to a whole bag.

How do I measure my lawn?

Multiply length by width in feet for each rectangular section and add them together. Split odd shapes into rectangles and leave out beds, patios, and the driveway.

How much grass seed per 1,000 square feet?

It depends on the grass type and whether you are seeding bare soil or overseeding, so this app does not guess. Use the rate printed on your bag.

How much seed do I need to overseed?

Type the overseeding rate from your bag instead of the new-lawn rate. The math is the same.

What does this not include?

Price, starter fertilizer, topsoil, straw or mulch cover, watering, and germination or coverage results.
