Unfortunately, garages are one of the worst places to store grass seeds, despite their proximity to yards. Garages are hot and humid, two environmental traits that are detrimental to grass seeds. Grass seed has the best chance of survival in a dry space with temperatures ranging from 30 to 60 degrees Fahrenheit. 

With that in mind, the best place to store seeds is in a sealed container in the refrigerator or in the coolest part of your home. Also, limit your seeds’ access to sunlight for the best germination results down the line. 

The best time to plant grass seed depends on your local climate and whether you have cool-season or warm-season grass.

For cool-season grasses (like tall fescue), the ideal time to seed is late summer or early fall (typically August and September). During this period, the soil is still warm from the summer, but the air is cooler, creating optimal conditions for germination and root establishment before winter. There is also less competition from weeds. Spring is a secondary option, but cooler soil temperatures, the risk of a late frost, and less time for the grass to mature before summer heat can make it less successful.

For warm-season grasses (like St. Augustine), the best time to plant is from late spring through mid-summer (typically May and June), when temperatures are consistently between 75 and 90 degrees Fahrenheit.

In general, it is best to avoid seeding during winter or early spring, as cold soil and air can prevent seeds from germinating. For recommendations tailored to your specific grass type and climate, consider consulting a local lawn care professional.

Technically, yes, at least some of the grass seed you throw on the ground will germinate. If the area doesn’t have good drainage, rain or overwatering can move seeds before they have germinated, leaving your patches still patchy. What does grow won’t have strong roots if there isn’t proper aeration.

Many homeowners in warmer climates like this resilient, hearty grass because it can tolerate excessive heat and drought while developing into a lush lawn. Unlike other grasses, Bermuda grass grows and spreads quickly and can withstand excessive foot traffic. But whether Bermuda grass is good for lawns may depend on your geographic location, as this grass has a low tolerance for cooler temperatures, which causes it to go dormant and turn brown in the winter months.
