How To Read A Grass Seed Label

A practical reference for how to read a grass seed label and supplier conversations.

Use this reference

The seed label tells you what you are buying and which application rate to enter.

  • Species and cultivar: check suitability for your region, sun, and use.
  • Germination: the tested share that sprouted under lab conditions.
  • Pure seed and inert matter: how much of the bag is seed versus coating or other material.
  • Weed and other crop seed: inspect before buying.
  • Seeding rate: select the stated new-lawn or overseeding rate, usually per 1,000 sq ft.

Use the current bag label and local extension guidance rather than a single national seed rate.
