What's the lowest temperature you can plant grass seed?

Cool-season grass seed germinates best when soil temperatures are between 50°F and 65°F. This roughly corresponds to daytime air temperatures in the 60°F to 75°F range. An inexpensive soil thermometer, available at most garden stores, can help eliminate the guesswork.

Can you put grass seed down anytime?

Grass seed is best sown from late summer to mid-autumn; there is less competition from weeds, and the soil is warm, and damp from rain. Perfect for seeds to germinate. If you miss the opportunity to sow in autumn, try in mid-spring, but only if you can give the new grass plenty of water.

Will grass seed die if too cold?

If the daytime temperature is below 60^°F then soil temperature is below 50^°F, making it too cold; if there is frost or still a danger of frost, then it's too cold. If it's too cold, the grass seeds will likely rot.
