Pro Tips for Fertilizing & Watering After Your Aeration and Seeding


When you give your lawn the gift of aeration and seeding, it’s kind of like getting a whole new lawn.

All those fresh holes allow your lawn to breathe. New seed rejuvenates it and helps it grow thicker.

New lawn! And that’s how you need to treat it — a little more gently than an established lawn.

Watering after aeration and seeding changes a bit. Fertilizer is super important.
Proper irrigation is key after aerating and overseedingHere’s what to do:

Watering After Aeration and Seeding

Pretend you’re taking care of a new baby for a few weeks. Except you get to sleep at night.

Your new grass seed needs special attention, especially for the first 21 days or so that it takes to germinate.

When your grass is new, it needs more frequent watering in smaller amounts.

Plan on frequent light watering for the first month. Keep that seed consistently moist. But no big puddles, please. You don’t want to drown your new seed or wash it away.

This usually means watering your lawn two or three times a day for 15-20 minutes.
Make sure to irrigate your seed to help it germinateThis is really important. If you stop watering, either your seed won’t germinate or your precious new grass will die.

Watering Your Lawn After Germination

After four to six weeks, transition to longer periods of watering, but fewer times. You want your grass to have to search for water, sending its roots deeper into the soil. That encourages the roots to grow longer and deeper, which means your grass will be healthier.

Shoot for an inch or so of water a week over two or three sessions.

You want to water a bit longer now, about 45 minutes or so, so the water soaks into the soil nice and deep where the roots are developing.

Fertilizing After Aeration and Seeding

Just like a new baby eats multiple times a day, your new lawn needs fertilizing throughout the year.

That fresh new grass is hungry. Follow up your aeration and seeding with a regular fertilizing program.Lawn technician fertilizing after an aeration and overseeding

A Couple Other Tips

While watering after aeration and seeding and keeping that hungry new grass fed are key, keep these tips in mind, too:

Back Off on Weed Killer

Don’t use weed control products for at least a month. A good way to keep track: if you mow weekly, mow at least four times before you break out the weed control.

We know, weeds often grow faster than your new grass, and it’ll drive you crazy.

But that weed killer will also kill your precious new grass. So hold off.

The one exception: if we do your lawn care. We have a pro-level product that will kill weeds without harming your new grass. We can use it the day we seed.

Mow High

Taller grass helps a lawn grow thicker and stay greener. As summer progresses, you should keep raising your mower blade. Shoot for 3 inches in June, 3.5 to 4 inches in July and August.
