- Calibrate the spreader and divide the seed into crossing passes.
Lawn seed FAQ
Is overseeding rate lower than new-lawn rate?
Often yes, but the exact rates depend on species and product label.
Should I add extra seed?
Use the label rate rather than automatically adding waste; too much seed can create weak, crowded seedlings.
