A carpet of lush, healthy grass is indeed a refreshing sight, so many homeowners in Ohio are choosing to plant grass on their property. If you are planning to grow grass or repair bald patches on your lawn, keep in mind that the climate, your region, and the soil temperature play significant roles in deciding when to plant grass seed in Ohio.

Cool season grass is generally recommended for Ohio lawns. The best time to plant them is around early to mid-spring or early in the fall season, when the ground temperatures are cool enough.

Check Your Region


While grass is relatively low maintenance compared to other plants, they also require the ideal conditions and temperature to germinate and grow successfully. If you are thinking, ‘when should I plant grass seed?’, consider the region where your property is located.

Located in the Midwestern region, the Buckeye State has hot and humid summers and cold, snowy winters. If you are planning to plant grass in Ohio, here are the optimal times to do so:

  • For Northeast Ohio, the ideal time to sow grass seeds is between mid-August to mid-September
  • Central Ohio homeowners can plant grass seeds anytime between mid-September to mid-October
  • In Southern Ohio, planting can be started by mid-September and can be stretched until around the end of October.

Check the Grass Classifications


There are different grass varieties, but they can be classified into two main groups – cool season grass and warm season grass.

1. Cool Season Grass

Varieties of cool season grass are commonly found in Ohio lawns and the rest of the northern regions of the United States.

They thrive in the cool temperatures of spring and fall but may become dormant during the hot summer months. Examples of cool season grass include:

  • Kentucky bluegrass
  • Fine fescue
  • Perennial ryegrass
  • Bent grass

2. Warm Season Grass

As the name implies, warm season varieties grow well in warmer climates, particularly in the southern part of the United States. The best time to plant warm-season grass is around late spring when the ground temperatures are rising.

Here are some of the most common varieties of warm season grass:

  • Bermuda grass
  • Augustine grass
  • Centipede grass
  • Zoysia grass

When is It Too Late to Plant Grass in Ohio?


If you are planning to plant grass seed in June, it might already be too late to grow cool season varieties but don’t fret, because this is the best time to plant warm season grass.

They are drought-tolerant and will be able to withstand the hot summer months.

Harsh winters are also not favorable for grass growth, but if you are thinking, ‘can I seed my lawn in November or December?’ The answer is yes, you absolutely can.

Planting grass seed in Ohio early in the spring or fall seasons sure is the best option, but if you are running a little late, another alternative you can consider is dormant seeding.

Dormant Seeding Technique

This method allows planting grass seed in Ohio to be done when the ground temperatures are cold, below 50 degrees Fahrenheit, but not freezing.

Sowing seeds at low temperatures puts them in a dormant condition through winter, allowing them to germinate and grow as the ground warms up in spring.

  • For this method to be effective, grass seed must be properly incorporated into the ground to establish good seed-to-soil contact.
  • For small patches of lawn, you can use a hand rake to loosen up the soil.
  • But if you are working on a larger area, a power rake or vertical mower might be necessary.
  • Once the seeds are sown, water your lawn thoroughly. This should be enough to keep the ground moist until spring.
  • A snow cover of at least an inch is a good addition to protect your grass seeds from fluctuating weather conditions.
  • From here, you can just sit back until spring comes and wait for your grass to grow.

Germination Rates

In general, the germination rate depends on the variety of grass. As an example, perennial ryegrass will germinate within 3 to 5 days, but for Kentucky bluegrass and tall fescue, it will take about 10 to 21 days before these varieties of grass start growing in Ohio lawns.

To address this, many experts recommend planting a blend of different grass seeds. Doing so not only improves the resistance of your lawn against harsh climates but also allows it to combat pests and diseases.


Caring for your lawn is no easy feat; it takes effort and the right timing. Knowing the different varieties as well as when to plant grass seed in Ohio ensures a thriving, verdant lawn.
