When to Plant Grass Seed in Pennsylvania

4 min read

If you are wondering when to plant grass seed in Pennsylvania to achieve the best results, the experts at Jonathan Green are here to help.

The Jonathan Green name has represented high-quality cool season grass seed, innovation, integrity, determination, and a commitment to excellence since 1881. Today, six generations later, we remain committed to producing superior lawn and garden products.

We supply grass seed, soil enhancers, fertilizer, and organic lawn and garden products to professional customers, such as sod growers and independent retailers, throughout the Northeast, Mid-Atlantic and Midwestern United States.

Plant in Early Fall

Cool season grass seeds, such as Jonathan Green Black Beauty®, fare best in the early fall in Pennsylvania, when the air is cooling down, but the soil is still warm. Weed growth tapers off in the fall, so your new grass won’t have to compete for sunshine, water and nutrients. It will also have the benefit of two cool growing cycles before the heat of summer sets in.

Use the Best Grass Seed You Can Find

Used by leading sod growers across the country, Jonathan Green’s genetically superior Black Beauty® grass seed creates a lawn full of grass that:

  • Is deep rooted, can grow up to 4 feet deep;
  • Exhibits an invisible waxy coating that wards off disease and locks in moisture;
  • Is dark green, lush, and uniform;
  • Grows well in both the sun as well as the shade;
  • Is endophyte-bred for natural insect resistance.

Feed Your Lawn & Feed Your Soil

There is nothing more important you can do for your lawn than to address the poor soil it is grown in.  Since the soil is the foundation of the lawn, strong, healthy soil will result in a lawn that looks good and is easier to maintain.

Lawns grow best in a soil that is neutral to slightly acidic (between a 6.2 and a 7.0 reading), so it’s important to balance the pH when you plant seeds.

An application of Jonathan Green’s MAG-I-CAL® Soil Food will help to raise the soil’s pH and, at the same time, help the lawn grow greener and healthier. The fast acting, soluble calcium carbonate helps to develop cell walls and prepare grass plants for winter, while reducing disease potential. You can apply MAG-I-CAL® the same day as you plant your grass seed.

If your soil is very hard or compacted, Love Your Soil®  will loosen and aerate it. It will also feed the soil microbes, making the lawn soil more alive and porous, and enhancing root development. Love Your Soil® can be applied the same day as the grass seed and works best when the soil temperature is at least 55 degrees Fahrenheit.

When seeding your lawn, seed-to-soil contact is the key to achieving maximum germination. Once your soil has been prepared, apply the Black Beauty grass seed with a spreader. Lastly, keep the seed bed moist for a few weeks while the grass seed germinates.

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, which will help you care for your lawn and encourage it to thrive.
