Frequently Asked Questions
Where do I find the coverage rate for my grass seed?
Coverage rate, in pounds per 1,000 square feet, is normally printed directly on the grass seed packaging and varies by grass species and blend.
What if my lawn is not a simple rectangle or circle?
Split an irregular lawn into a few simpler rectangular or circular sections, calculate each section separately, then add the seed amounts together.
Should I buy extra seed beyond the calculated amount?
Buying a small extra margin beyond the exact calculated amount is common practice, to allow for uneven spreading, edges, and any bare patches that need reseeding later.
