Container Maintenance

Container Gardening

Colorful annuals planted in containers can welcome each new season by framing a front entryway, adding a splash of color to an otherwise blank deck or patio, bringing an accent to a front porch and more. We take the guesswork out of what annual goes where and which ones grow together. Our use of self-watering pots relieves the burdensome chore of watering every day.

Pollinator Garden

Pollinator Garden

Incorporating a pollinator garden into your yard is a great way to assist mother nature’s helpers. When done properly, pollinator gardens attract a multitude of butterflies, bees, birds and even hummingbirds. A pathway into the pollinator garden is an excellent way to make the garden interactive.

Water Features

Water Features

There is nothing like the relaxing sound and movement of water. Choose from many styles of real granite or handmade columnar fountains and vases. Water features are a low-maintenance, high-reward addition to anyone’s existing or new garden.



Nightscaping can enhance the features of our homes, creating shadows to uplight trees; highlighting an otherwise dark corner to the entrance; or washing a wall with lights for a subtle yet dramatic effect. Nightscaping helps add security, value and curb appeal.

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 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. Mark is a member of the Association of Professional Landscape Designers and Proven Winners Certified Landscape Professionals.

He thoroughly enjoys new construction, as well as taking a client’s landscape from overgrown and outdated to one that is modern, and one that both the client and Thomaschefsky are proud of.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."
