Can you plant grass seed in 40 degree weather?
In respect to this, how warm does it need to be for grass seed to germinate?
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.
Furthermore, can I plant grass seed if it freezes at night? Freezing temperatures generally have a negligible effect on grass seeds before they germinate. However, real problems can occur if temperatures drop below freezing before newly emerged seedlings have had a chance to develop sufficiently.
Keeping this in view, how cold will kill grass seed?
Temperatures above 90 F or below 50 F prompt the seeds to abort any growth and return to dormancy.
Is it too early to plant grass seed?
Grass seed needs the correct soil and air temperature, as well as moisture content, to sprout. Planting it too early in the spring can result in less-than-ideal germination, because the seeds can die off or become unproductive. Sow grass seed once the danger of frost has passed.
