Since 1881, Jonathan Green has combined technology and tradition to produce the finest grass seed available. We have experimented with grass seed, fertilizers and soil treatments to understand what it takes to have a healthy lawn. Over five generations, we have consistently improved our products to make sure they deliver excellent results year after year.

The Keys to Successful Overseeding

The best time for overseeding your lawn in Maine is in the late summer or early fall (mid-August to mid-September).  The soil is warm, temperatures are cooler, autumn rains are more plentiful, and weeds are less active, creating an excellent environment for seed germination before leaves start falling and the winter cold arrives.

Choosing the right grass seed another crucial element of successful overseeding. 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 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;
  • Is drought-resistant;
  • Is endophyte-bred for natural insect resistance.

The next key to successful overseeding is good seed-to-soil contact. Clean out dead grass, remove as many weeds as possible, and get rid of rocks, sticks or other debris.

Loosen compacted soil about a half-inch deep with a rake or garden weasel to give the new roots a good chance to grow in the loosened soil.  Jonathan Green Love Your Soil® will loosen and aerate it. It will also feed the soil microbes, making the soil more alive and porous, and enhancing root and root mass development.

Use a soil pH tester to ensure that the pH of the soil is between 6.2 and 7.0. To rapidly increase the soil’s pH and help the lawn grow greener and healthier, use Jonathan Green MAG-I-CAL®. It can be applied the same day as the grass seed is spread.

This is also a great time to apply Veri-Green Starter Fertilizer for Seeding & Sodding, our high phosphorus formula that helps build a vigorous root system and gets new grass plantings off to a fast start.

Keep the seed bed moist for a few weeks while the grass seed germinates. Plan to water daily and possibly twice daily (unless it’s raining) until your new grass is two inches high.
