Lawn Irrigation FAQs, answered by experts

Unfortunately, no. Grass seeds need a lot of moisture until they become sprouts, so this is an especially sensitive time. While they'll dry out if they get dehydrated, over-watering creates other problems. The grass seeds don't recover because they can just wash away or even rot, making for low germination rates. The ones that do germinate after being pushed under the soil may start to sprout only to die from lack of sunlight.

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.

Soaking grass seeds in water before seeding is called pre-germinating. It’s not necessary but can be very helpful in some cases. Some grasses like are very slow to germinate, and basic seeding on the ground is unlikely to be effective—that’s especially true of cool season grasses like Kentucky bluegrass, rye grasses, and Bermuda grass. Soaking these seeds in a bag or bin of water for one to four days beforehand can give the grass the start it needs to survive.

If your lawn and general landscape are struggling, consider calling a local landscape specialist to suggest lawn amendments, local plants, and hardscape changes to boost the long-term health of your outdoor space. While you may be able to take on small projects yourself—such as reseeding your lawn or testing the soil—a professional can help you build a plan to bring a struggling yard back to life quickly.

If you’re wondering whether grass seed will germinate on top of soil, the answer is yes. In fact, it’s the best way to plant your grass seed. Spread seeds in an even layer on top of loose, fertile soil will allow them to germinate and grow strong roots. Topping them with a thin layer of straw will help them retain moisture and stay put, as well as protect them from getting eaten by animals.
