The Benefits of Aerating, Overseeding, & Topdressing


If you’re not satisfied with the way your lawn looks or have patches of your lawn that seem dry, sparse or overtaken by troublesome weeds, then Aeration & Overseeding is a simple solution for you.

Believe it or not, the path to a healthier and more lush lawn actually begins in the fall when the temperatures slowly start to come down. How you prepare your lawn for the winter months can have a dramatic effect on how your lawn looks in the next season ... We believe the difference will amaze you! Here’s a more in-depth look at the Aeration & Overseeding process:


Throughout the normal course of the year, your soil can become compacted from foot traffic, your lawnmower, snowfall, and normal rain and irrigation. As a result, your lawn loses its ability to absorb nutrients properly over time. When we aerate your lawn, we perforate the soil, creating several small holes through which nutrients and water can reach your root system adequately. This lawn aeration process allows the roots of your turf to spread and strengthen, while simultaneously reducing thatch that robs your yard of nutrients and water.


It’s common to find areas of your turf with bare patches or noticeable thinning. Patchy lawns tend to look dull and can be more susceptible to insects, weed growth, and grass diseases. After aeration, we spread high-quality seed in the holes that have been created so that new grass can fill in quickly. This reduces the available real estate for weeds to grow and helps to prevent grass disease and insect damage.


You may not realize it, but your lawn is alive with microorganisms that need organic matter to thrive and feed your turf, and that’s why composting is important. The organic matter that is naturally found in compost feeds your soil’s friendly fungi and bacteria, which in turn helps to maintain a lush, healthy lawn. An added benefit to using Green Sphere is that we use high-quality bagged material that does not have the pungent odor you might associate with compost treatments for lawns.

Moisture Manager

To ensure that your new seeds establish in your soil properly, we use moisture manager products. These moisture management products help your turf roots maintain the water they need to flourish, even in times of drought and water restriction. Studies have shown that Moisture Managers can reduce your watering requirements by up to 50%, meaning you’ll spend less time and money on watering your lawn.

Slice Seeding

Slice seeding is a mechanical seeding method that uses vertical blades to cut small slits in the soil 1/2"-1' deep. The machine then drops seeds into these slits to ensure good ground contact and germination. This is a great method to use for large-scale lawn renovation projects that are starting from scratch. We also find this method to be great for properties with shallow irrigation lines or fences that would be damaged with aeration. With slice seeding, there are no soil plugs all over your lawn, which can be an attractive benefit to this method of lawn maintenance.

Liquid Aeration

All lawns need aeration to relieve compaction and allow nutrients into the soil, but there are some situations when aerating will damage shallow irrigation lines or fences. Liquid lawn aeration is a great option in these cases! Liquid lawn aeration is a method of applying a thatch reducer and organic biostimulant wetting agent to your grass. The results reduce the top layer of thatch that absorbs your turf’s vital water and nutrients and loosen and feed the soil. This process and the results take the place of mechanical aeration, and the benefits of liquid lawn aeration mean that we are able to reduce your soil’s compaction and aerate soil that otherwise might not be accessible. Liquid lawn aeration is a top choice for new construction homes and developments with subsoil that has been severely compacted.
