Midwest Wildflower Pockets

Wildflower Pockets

Native wildflowers are more attractive to pollinators than non native wildflowers. Wildflower pockets benefit the wildlife as well as the environment by having less grass to mow. Wildflower pockets also benefit you by providing a splash of color on your property.

Prairie Pockets

Prairie Pockets

Reduce your carbon footprint and attract certain butterflies with Forbes (flowers). Butterflies enjoy nectar from Forbes, and you'll enjoy interesting characteristics from the grasses year-round.

Rain Gardens

Rain Gardens

Filter pollutants from runoff. Properly installed rain gardens can absorb more runoff than a typical lawn. Capturing rainwater in a rain garden can help with the rush of water after a large rain event.

Grass overseeding


Overseeding introduces new cultivars that are more drought and disease resistant, helping to fill bare spots in the yard and lessening our dependence on chemicals. A thicker, healthier turf stifles weed growth.

Lawn core aeration

Core Aeration

Mechanically removing a core of the soil allows the lawn to breathe, reduces compaction, and allows air and nutrients into the soil.

Lawn top dressing

Top Dressing

Compost is the ultimate tool to achieve a thicker, greener lawn. It increases the organic matter in the soil, allowing for a quicker green-up in the spring.

And Much more!

Owner Mark Thomaschefsky is a graduate of Kishwaukee College with a degree in landscape design and golf course management, and has been a landscape contractor serving the Sauk Valley area since 1988.

He thoroughly enjoys new construction, as well as taking a client’s landscape from overgrown and outdated to one that is modern, and one that both the client and Thomaschefsky are proud of. It is also very satisfying to see a worn-out, weed-infested lawn be transformed into one that can be the envy of the neighborhood.

Mark believes in being stewards of the land. "We have only one earth and if we don’t do our part to take care of it," he says, "future generations will not be able to enjoy the natural resources we have today."

I am very pleased with the outcome and will definitely contact him in the future when I need additional work to be done.
