Hi, I'm John Steiner, Director of Operations for NaturaLawn of America, the leader in organic-based lawn care. Today we are going to talk about the benefits of aeration and seeding to a homeowner's lawn and cover three main points.

First, what exactly is aeration and seeding? Second, what are the benefits to a homeowner's lawn and last when is the best time to do aeration and seeding? What is aeration and seeding? Aeration is the physical removal of soil cores from the lawn. These cores can be removed manually or by machine, which is what's being done today.

As you can see, a core about 1-2 inches is removed thousands of times in the average home owner's lawn. When seeding to ensure the highest level of success when sowing new seed, the lawn is double aerated in a crisscross pattern. By doing this, there will be twice as many holes for the seeds to fall into. It's quite simple—the more holes, the thicker the lawn will be in the end.

Core aeration and seeding is the best mechanical and cultural practice a home owner can do to improve the overall quality and health of their lawn. Many of the benefits of aeration and seeding include: reduction in soil compaction, increased oxygen uptake by the plant roots, increased root development, improves nutrient uptake, improves the plants ability to use water more effectively, and allows for the lawn to stand up to environmental and natural stresses such as heat, insects and disease problems.

In addition, when the cores are removed, they're deposited onto the surface. Within each soil core are millions of microbes. These microbes are hungry and begin to feed on the thatch and the surface debris thereby breaking them down. This plentiful food source is needed for these microbes to multiply this increase microbial activity helps to sustain a healthier lawn.

When seeding the lawn, it is important to apply the right amount of seeds based on the variety or blend being used. This information can be found on the seed label. For example, Tall Fescue is seeded at a rate of 5lbs. per 1000ft. Much like core aeration, it is best to apply the seed in a checker board or crisscross pattern. This will ensure enough seed will fall down into holes. Grass seed will not grow unless there is good contact with the soil to do this.

The final step in seeding the lawn is to back drag with a metal mat. This mat is similar to what is used on a ball field. This knocks the seed off the surface and into the holes. This provides good seed to soil contact. The best time of year to aerate depends on what type of lawn grasses are growing. Cool season grasses, such as Kentucky Bluegrass or Tall Fescue, should be aerated and seeded in late summer through fall. Generally speaking, this will be from mid-August to mid-October. Warm season grasses, such as Zoysias and Bermudas, should be aerated when they are more actively growing…usually early summer.

So, by following these processes for aeration and over seeding you too can have a healthy lawn that's environmentally friendly and uses less pesticides. Thank you for watching today and for more information please contact us on our website.

My lawn is beautiful.  It has never looked this good.  It looks like lush green velvet.  We only had one dandelion this spring and it was on the edge of our property, so it must have been the neighbor’s!

Jennifer L. Lloyd – Bear, DE

For over 22 years, NaturaLawn of America has been creating naturally beautiful lawns that are safer for you, your family, pets and the environment.  Of course our satisfied customers say its best!
In less than a year, my lawn has gone from one of the worst on the block to among the best.  This is quite an accomplishment considering we have well water and, therefore, never water the lawn.  The  service is also top notch – friendly, knowledgeable and always willing to explain why they’re doing what they’re doing.

Stewart Kaufman – Southbury, CT

NaturaLawn of America has cared for my lawns now for 10 years (2 houses) and I am completely satisfied with your company.  My service technician is friendly, caring and knowledgeable.  I’m happy with the results, how you care for my lawn and the prices you charge – happy enough that I recommend you to others and I tear up ads from competitors without even reading them.
My husband and I are currently acquiring a house in New Hampshire.  There is no question that I will want NaturaLawn of America service at that house.  It is a true pleasure to work with a “national” company that treats their customers in a local business manner.

Anne Bullitt – Newark, DE

I’m just dropping you a note to let you know that we are very pleased with your lawn service, the way we are treated and the beautification of our lawn.  Many families have seen our lawn and are very impressed by the way it looks.  They are even more impressed that you are an organic-based company and use 85% less chemicals and pesticides.  We have referred many of our friends and neighbors and will continue to refer people as the opportunity arises.

Jack & Sherrie Decker – Plainview, MN

Our lawn is beautiful.  Thank you for the great results AND for protecting my family and the environment from unnecessary chemicals and pesticides.  It’s nice to have a lawn care company that is concerned about my lawn, my family and the environment.  When people are looking for a healthy, nice lawn, friendly service AND a safer lawn care option, I highly recommend they call NaturaLawn of America.

Pete Plimmer – Wilmington, DE

You are doing a great job! We are glad we switched to NaturaLawn of America and are spreading the word about the super job you do.

Steve Pfannenstein – Rockville, MN

I wanted to write and let you know how pleased I am with NaturaLawn of America.  I had never used a lawn service before.  I’m against putting more chemicals into the environment, so I decided to see what you could do organically.  My lawn was 1 ½ years old – builder grade seed on builder soil! It was a lawn in need of some help, but I didn’t know how wonderful it could look.
Two days ago, my neighbor (who used one of the top chemical lawn companies) sounded a little baffled and asked what I do to my lawn – It looks like a carpet!  We just smiled and said “NaturaLawn of America”.  That’s when I took a good look at my lawn and everyone else’s - our lawn is thick and green.  Despite the recent drought, despite our lack of attention to our lawn, and despite its humble beginnings, it is a magnificent piece of work.

Paul & Doris Pavlichek – Mount Airy, MD

This is our second year with NaturaLawn of America and I can’t say how much we appreciate your work. The yard is awesome!
