Best Grass Seed for Illinois

4 min read

Plant grass seed in Illinois and use high-quality Jonathan Green products to achieve the best lawn in the neighborhood!

Jonathan Green has been working for more than 100 years to bring beautiful dark-green lawns to our clients using only the highest quality materials.

Since 1881, we have experimented with turfgrass varietals to breed our genetically superior grass seed. We are dedicated to providing our clients with the absolute best, so all of our products are rigorously tested to ensure that they perform to the highest standards.

Grass Seed That Provides the Best Results

If you want the best-looking grass, choose the highest quality grass seed mixture. Jonathan Green’s genetically superior Black Beauty® grass seed creates a lawn full of grass that:

  • Is deep rooted (can grow roots up to 4 feet deep);
  • Exhibits an invisible waxy coating (like the waxy skin on an apple) that wards off disease and locks in moisture;
  • Has leaves that are dark green, lush, and uniform in texture;
  • Grows well in both full sun as well as partial shade;
  • Contains beneficial endophytes for natural insect resistance.

Black Beauty® Ultra is most similar to what is grown on sod farms.  The mixture contains exclusive varieties of tall fescue, Kentucky bluegrass and perennial ryegrass.  These cool season grasses grow a naturally dark-green and beautiful lawn with excellent heat and drought tolerance.  Black Beauty Ultra® grass seed germinates in about 14 days.

Black Beauty® Fall Magic™ has been specially formulated for successful fall seeding and contains several cool season grass types, including Black Beauty® tall fescues. It can be used in sun and shade lawn areas on established lawns or to start new lawns from scratch. Black Beauty® Fall Magic™ repairs summer damage and provides an attractive, thicker, greener lawn, with germination in 10 to 14 days.

A Black Beauty® lawn will redefine your idea of what a good lawn is supposed to look like. We encourage you to read more about Jonathan Green’s revolutionary New American Lawn Plan that will help you care for your lawn and encourage it to thrive.

Feed Your Lawn & Your Soil

Before you plant your grass seed mixture, make sure that you also have the following Jonathan Green products on hand:

  • MAG-I-CAL® Soil Food – Test your soil to ensure the pH is between 6.2 and 7.0. If it’s not, MAG-I-CAL® can be used immediately before seeding (and continuously until you improve the pH level adequately) to help the lawn grow greener and healthier. MAG-I-CAL® comes in two custom formulas – one for acidic soil and one for alkaline soil.
  • Love Your Soil® – If your soil is very hard or compacted, Love Your Soil® will loosen it. It will also feed the soil microbes, making the soil more alive and porous. With more porous soil, air, water and roots can move more easily from the surface deep-down through the soil.
  • Veri-Green Lawn Food for Seeding & Sodding – This high phosphorus formula is specially formulated for seeding and sodding. It helps to build a vigorous root system and gets new grass plantings off to a fast start for a thicker, greener lawn.

Once your new grass has grown at least three inches, it is ready to be mowed. We call this giving the grass a haircut; it invigorates the young grass and causes the root system to grow deep.
