Assumptions and limitations
What the estimate assumes
- The label rate applies uniformly across the area.
- Entered weight is seed product weight, not pure live seed.
- Bag count rounds up to whole bags.
What it does not determine
- Cultivar, climate, season, soil, and application method affect establishment.
- More seed does not correct poor preparation or watering.
- Always follow the product label and local restrictions.
Frequently asked questions
Should I use the new-lawn or overseeding rate?
Use the rate on the seed label for your specific task. Overseeding rates are often lower, but products differ.
What does pounds per 1,000 square feet mean?
Multiply your area in thousands of square feet by the stated rate. The calculator performs that conversion.
Does the calculator account for germination?
No. Use the manufacturer’s labeled rate, which is specific to that blend and seed quality.
