Cold Season Grass Seed

Cold Season Grass Seed

Cold-season grasses thrive in lower temperatures and grow very quickly in the fall and spring. Most cold-season grasses can hold up against hard weather despite the season.

Fine Fescue Grass

Fine Fescue Grass

Fine fescue grass is a rapidly-growing and is frequently used in seed mixes, often mixed with ryegrass and bluegrass seeds. This grass cannot bear dry and hot weather but can withstand temperature fluctuations and thrives in both shade and full sun. It is best to plant in an area with lots of trees.

Kentucky Bluegrass       

Kentucky Bluegrass       

One of the most commonly planted grass seeds in the northern regions of the US is Kentucky bluegrass, as it's a reliable seed that keeps lawn healthy long-term. It does well in both partial shade and sun, and it is incredibly resistant to disease.

Perfect location: Northeast US

Perennial Ryegrass

Perennial Ryegrass

This soft and thin lawn grass stands up quite well to foot traffic and grows well in shade and sun. Perennial ryegrass is typically combined with Kentucky bluegrass seed to develop grass that's highly tolerant to shade. The disadvantage of ryegrass is that it grows thicker in certain areas than others, which can make your yard look uneven. It is perfect for areas where kids or dogs would be playing often.

Perfect location: Northeast US

Tall Fescue

Tall Fescue

Tall fescue is great in dry and hot weather as well as the cool season. It's tough, thick, and can tolerate high amounts of foot traffic. Similar to ryegrass, it can grow thicker and darker grass in some places while it grows thinner, lighter grass in others.

Check out our list of FAQs below to learn more.

How much lawn seed per square foot?

Typical seeding rates for a lawn is 3 to 5 lbs. per 1,000 square feet. To understand how much seed
you need, you would determine the number of square feet you have to plant and multiple that by 3 to 5.  This step is especially important if you buy lawn seed online, you want to make sure you have enough
delivered. 

Example – Assuming your back yard is 80 feet wide and 50 feet deep. This would be 4,000 sf. (80 ft x 50 ft = 4,000 sf) You would need about 20 lbs. seed for this area. (4,000 sf / 1,000 x 5 lb seeding rate = 20 lbs)

Can I just throw down grass seed?

There are many factors that go into a successful lawn establishment.  However, the two primary factors are:

1) Seed to soil contact
2) Adequate water

You can just throw down grass seed, BUT you will be much more successful if you lightly rake the seed into the soil.  You do not want to bury the seed; just ensure the seed has good soil contact.

Adequate water is making sure the soil stays moist until the grass plants have established roots. You should lightly water multiple times a day while roots are being established.
 
After the grass plants have established roots, they can survive longer without being watered as frequently.

Which is the best grass seed for my lawn? How do I know which grass seed to buy?

The best lawn seed for your yard is dependent on where you live. There are three basic climate areas to consider when determining which grass would thrive in your area:

Northern regions where cool-season grasses thrive

Deep South/Gulf regions where warm-season grasses grow best

Transition zones between the Northern and Deep South/Gulf regions

You can learn more about the grass type that would be best for your yard here, and with Swell Seed Co, it's easy to buy lawn seed online.

When is the best time to plant grass seed?

This depends on the type of grass. Cool-season grasses are best to lay down in early Fall when temperatures are between 60-80 degrees. 2 weeks before labor day is generally a good time to plant. For the warm-season grass seeds, grow best when temperatures are between 75-90 degrees, making the best time to plant in late spring.

Why didn't my grass seed grow?

There are a lot of things that can prevent your grass seed from growing, such as the time you put it down, weather conditions, using too much or too little water, or poor soil conditions. It's also important to avoid using products on your grass that could prohibit growth, like weed control products.

Two of the most common reasons for poor grass establishment:

1) Seed was buried too deep or lacked soil contact.
2) Too much to too little water.

Best to broadcast the seed over the desired area and lightly rake the seed into the soil.  After seeding, do not bury the seed with a layer of mulch. Yes, the mulch will help hold soil moisture, but it can also prevent the seed from germinating if it is too thick. Keep the soil moist, so seeds do not dry out, until the plants have a well-established root structure.

Can I plant grass seed after using weed control products?

It's generally not recommended to use weed control products on your lawn, especially when you are trying to grow new seeds or revive your lawn.

How long is grass seed good for?

When stored in a cool, dry place and away from all temperature extremes, grass seed should last between 10-18 months from the testing date without a significant decrease in the germination rate. After this time the seed can still be used, but each year after that will see the germination rate drop. Most sources report a 10-20% decrease for every year grass seed is stored.
