Posted by Ryan Wolfe on Sep 29, 2016 4:47:05 PM

Summer is over and the hot, dry weather is finally gone. Your thick green lawn from the spring may have suffered a little damage from the stress of summer. There is a solution to whip your lawn back to it's lush green self! Our sod varieties are all grown to be drought tolerant and hearty but sometimes mother nature and other factors take their toll. In this blog we will talk about:

  • Reasons to over-seed
  • Over-seeding entire lawns
  • Patch jobs
  • Seed varieties & Rates

Reasons to over-seed

 It is a known fact in the turf industry that keeping your lawn thick does more than just provide an eye catching appearance. Keeping you lawn thick will also keep it healthy.

  1. A thick lawn will assist in keeping weeds from invading and taking over. 
  2. If you have an area thin out due to dense shade you can utilize a shade mix seed. Generally shade mix seed contains different types of fescues that do well in areas that receive less sun than tall fescue needs to flourish. 
  3. Fill in areas affected by pet urine
  4. Fill in areas affected by disease due to weather conditions
  5. Patch worn areas on sports fields to maintain a safe playing surface for athletes
  6. Fall is a great time for seeding cool season grasses such as Tall Fescue, Kentucky Bluegrass and Fine Fescue. There is less stress on the new seedlings from both heat and drought. There is also less competition with weeds since they are near the end of their growing cycle. 

Over-seeding your entire lawn

Before you over-seed, we recommend using as starter fertilizer such as our 10-10-10 to help the new seedlings quickly establish a strong root system.

One way to cover a large part of your lawn or even your entire lawn is by aerating and then broadcasting the seed across the lawn. You can utilize a hand held or push broadcast spreader or a drop spreader to apply the seed.  We will discuss the proper seeding rates later in this article. See your spreader's manual or the manufacturer's website for calibration info.

Another way to over-seed your entire lawn is to rent a "slit-seeder" from your local rental center or hardware store. Using a slit-seeder is a great way to be successful with over-seeding. It helps ensure that the seed has great contact with the soil by cutting grooves in the ground and depositing seed in each groove. The slit-seeder is relatively easy to use. It is self-propelled and is adjustable to apply various grass types at different rates. You will want to over-seed in a "criss-cross" patter to ensure ample coverage. See the seeder's manual or manufacturer's website for calibration info.

Patching small areas

Some times you may have smaller areas to concentrate on. These could be areas affected by fungus due to the humid summer weather or maybe even spots caused by urine from family pets. 


To patch a small area:

  1. Start by raking the area vigorously using a stiff garden rake. Keep in mind you should only have to break up the top 1 to 2 inches of soil. At this time you can also amend the soil by adding a premium topsoil or compost to the area.
  2. Hand spread the seed evenly across the area. Too much seed is not necessarily a good thing. 
  3. After seeding you can lightly walk across the area or tamp the area with a shovel or rake. The seed does not need to be covered by soil to germinate. 
  4. Water lightly at first. You do not need to saturate the patch but do not let it dry out. If you use too heavy of a stream it will spray the seed out of the area you are working on. The idea is to keep the seed in place until it germinates. 

Seed Varieties and Rates

Below we have listed seeding rates on the seed varieties we offer. These rates are good guidelines to follow and should be used for both broadcasting seed or slit-seeding. You can click on each seed variety below to find out more. 

Seed Variety Over-seeding Rate Approximate Germination Period
Tall Fescue 3 to 4 lbs/1000sq.ft. 7 to 14 Days
Kentucky Bluegrass 1/2 to 1 lbs/1000sq.ft. 14 to 21 Days
Shade Mix  5 lbs/1000sq.ft. 7 to 14 Days
