Here are some essential facts about lawn seeding that will help you avoid any delays in getting the enviable lawn you’re after.

1. The Best Time to Seed a Lawn

Let’s start with the first important factor to consider when seeding a lawn: When should you seed?

Early fall is the best time to seed your lawn in Maryland. Temperatures start to cool down so the seed will have a chance to germinate and begin to grow before winter sets in and then keeps building up its energy for a growth spurt in spring. The strength it builds during these two seasons gives it the power to survive the scorching summer heat.

If you have to overseed or seed a lawn in the spring, it’s definitely doable because the conditions are OK. But, many times, lawn care companies will not sell a spring seeding without a fall seeding because spring isn’t as successful as fall. Finishing the job usually requires an additional fall seeding.

So, the best time to seed a lawn is in the fall because the lawn gets that extra time to build up energy and establish itself before that next growing season.

2. Should you Seed and Fertilize Your Lawn at The Same Time?

All lawns require nutrients to remain green and healthy. Developing strong, healthy roots takes quite a bit of energy. Unfortunately, most soils lack adequate nutrition for grass to grow well. That’s why proper fertilization is important.

In addition to air and water, lawns need nitrogen, phosphorus, and potassium. Nitrogen aids in new growth, phosphorus encourages root growth and potassium improves overall plant health and hardiness. These nutrients help your lawn thrive, while also enabling it to maintain health through stressors like drought, mowing, and heat.

This is why seeding a lawn and fertilizing can be done together as long as fertilization is performed correctly using the right type of product and in the right amount. Slow-release fertilizer is typically best at this time, and you never want to overfertilize when seeding.

3. When Should You Mow After Seeding?

Mowing weekly during the growing season is an important part of establishing and maintaining a healthy lawn. It encourages thicker growth and that thick grass stand will help keep weeds out.

This is especially important in the spring and summer when grass grows more quickly.

When should you mow after seeding? When grass first germinates, it’s really tender. It’s important to wait seven to 14 days until the seed has germinated to mow. Don’t collect the clippings; let them fall on the ground so you recycle nutrients and any leftover seed your mower may have picked up.

4. How to Seed and Beat Weeds Simultaneously

When you’re attempting to grow grass or fill in bare spots in your lawn, you’re trying to create the ideal environment for seed to germinate. So, naturally, weeds will just get in the way.

The same can be said for grass seed and crabgrass preventer.

5. Lawn Seeding and Lime Treatments

Some lawn care professionals will test your soil when they come to your property for the first time to discover its pH balance.

If your soil needs some correction with lime treatments, that can be done at the same time as seeding or overseeding with no negative impact on germination. In this case, you’re just making the soil better to encourage grass growth. 

6. The Aeration and Overseeding Power Combo

When your lawn is tired, thin and has bare spots, core aeration and overseeding can revive it.

A compacted lawn can become stifled and stop absorbing the key ingredients roots need to grow. During aeration, we use an aerator to pull small soil plugs from the lawn, giving the roots a chance to get the oxygen, water, and nutrients they need.

7. Watering Your Lawn After Seeding

After seeding and aerating the lawn, keeping that seed evenly moist is very important.

Typically, watering about one hour per section to get water down 1 to 2 inches into the soil is a good goal. Keep the seed consistently moist but not submerged.

If there’s no rain, you may have to water twice a day to maintain this consistent moisture during germination -- for about 10 to 14 days. Then you can reduce watering to once a day for 30 minutes each section until the lawn is fully established.
