Seasonal planning
Memorial Day Overseeding
Start with the planting window, not a product.
Late May can be too warm for reliable cool-season establishment and unsuitable for some warm-season projects. Ask a local extension office about soil temperature, summer heat, irrigation restrictions, and the best window for your species and site.
What to verify before seeding
- Your grass species and whether late spring is an appropriate local establishment window.
- Soil temperature and the near-term heat forecast, not only the calendar date.
- Whether you can maintain even moisture through establishment without violating restrictions.
- The current package label, lot identity, composition, application rate, and storage history.
When to wait
Wait when the species, package identity, irrigation capacity, or local planting window is unresolved. A retailer listing, catalog score, coating claim, or community report does not prove establishment speed or fit for a lawn.
Use the planning tools conservatively
The quantity calculator is a catalog-rate estimate only. Confirm the current package's rate, coverage, and bag size before buying or applying seed.
