How to Choose the Best Grass Seed

Revitalizing your lawn with grass seed is the most affordable options available to you. Unlike hydroseeding or laying sod, planting grass seed requires very little technical knowledge or special machinery.

Your lawn growth’s success depends on several factors, such as the climate you’re in, the type of soil you have, the amount of grass you need, and so on. So it’s worthwhile to do some research before you waste money on a seed that won’t grow in your area or climate.

We’ll go over how to grow your grass lawn depending on your climate conditions, including information on the different types of grass available, as well as several other factors to consider before purchasing.

Types of Grasses and Their Features

Knowing the types of grass seeds available and the environments they thrive in allows you to choose the right type of seed for your lawn. Usually, Northern regions grow cool-season grasses, and Southern areas grow warm-season grasses. Regions in between can grow both with proper care.


Bahiagrass is a warm-season turfgrass that’s tough and well suited to heat and humidity. It has a rough texture and, for this reason, can handle heavy foot traffic.

Bermuda Grass

Bermuda grass is another warm season with excellent weed resistance. It is also water-resistant and drought-tolerant, and overseeding it with rye provides a green lawn during winter.

Kentucky Bluegrass

Kentucky bluegrass is the best choice for the cooler northern areas. Sunlight and a regular water supply are needed for a beautiful and consistent bluegrass lawn.  

Centipede Grass

Centipede grass is a very low-maintenance turfgrass that’s tough and low-growing. This grass grows best in the warm-season and thrives in slightly acidic conditions. It has a rougher texture than most turfgrasses with excellent weed resistance.  

Perennial Ryegrass

Perennial ryegrass is a cool-season grass that germinates quickly and holds up to moderate to high foot traffic. Ryegrass is a common addition to this cool-season grass for overseeding.

Warm-Season Grass

All grasses fall into two general categories: warm and cool season. Warm-season grasses do very well in the warmer regions of the country. Examples include Bermuda, buffalo, St. Augustine, and Centipede.

As you can imagine, warm-season grasses achieve peak growth in the middle of summer, or in warm climates. These grasses typically require full sun to thrive.

Cool-Season Grass

Cool-season grasses are the ones that grow in the northern regions of the country. They are often tall and thin. Common cool-season grasses include red fescues, perennial ryegrass, and Kentucky bluegrass. This type of turf grows the most during the cool seasons of spring and fall.

One key factor in choosing the right grass seed simply depends on where you live. You don’t want to plant warm-season turf in Vermont or fine fescue in South Texas.

How to Test Your Soil

Before you spend any money on grass seed, you first have to test your soil. Grasses have different pH environments where they thrive best. Most turf grass seed grows well in well-aerated soil with a slightly acidic pH between 6 and 7.

To test your soil, you will need to obtain a soil test kit from your local extension office. To take the soil test, gather some soil samples from several places around your lawn, and put them in the soil test bag.

It should take about a week or two to get your results back, depending on your region. Also, expect to pay about $10-$20 for the test. It’s also important you plan for the test ahead of time before you plan to seed.

Best Time to Grow Seed

The best time to grow your grass depends on where you live. If you live in the North, you’ll want to wait for the warmer temperatures. This is around April or early May, and seed until mid-June.

However, the best time is around September when there are more rain and cooler temperatures, which helps the roots to grow and spread much faster. Planting too early in the summer will cause your seeds to dry out quickly.

Wear and Tear

It’s important to consider how much wear your lawn will experience as you select a grass seed. If you have a family or pets that enjoy running around the lawn yard, you should opt for a grass tough grass choice. Kentucky bluegrass is a perfect choice and works best in these conditions – it’s also self-mending.

The turf also works well to fill in bare spots that have been damaged. However, Kentucky bluegrass is more demanding in terms of care and requires more watering, mowing, and fertilizing to look its best.

How Much Grass Seed Do I Need?

Each grass seed varies, but the sowing rates coverage for new lawn is shown on the packaging. It’s essential to always order 10% to 20% more than needed to accommodate errors in spreading and measuring. More may be required if you live in an area with a large bird population (as me how I know).
