A Lawn Care Program Designed for Your Lawn

Whether it's shady, sunny, sloped, or flat, your lawn deserves to be lush and healthy. We can improve the beauty of your lawn with our time-tested Lawn Care programs and Liquid Aeration. We can protect your lawn from pests with our Grub & Insect control. We can even keep your Small Trees and Shrubs looking good with our fall deep root feeding. 

Lawn Fertilization & Weed Control

Balanced fertilization, broadleaf weed control, and crabgrass preventer applied at the most ideal times throughout the season.

Liquid Aeration

Liquid aeration loosens topsoil and encourages deeper rooting to allow for greater oxygenation of the root zone.

Grub & Insect Control

Although you may not see them, in most lawns, grubs are lurking beneath the surface, chewing on the roots of your grass.

That Weed Guy came highly recommended. Unfortunately I live outside their current service area. Despite this, the person I spoke with took time to discuss my concern and make suggestions. She was kind, helpful, and did not rush the conversation, even though I was not going to be a "paying customer". That kind of excellent customer service tells me this is a business that cares!
