Our Lawn Treatment Services
Fertilizing
Fertilizer applied through the growing season feeds your grass so it greens up in spring, holds color through summer and recovers in fall.
Weed Control
We treat broadleaf weeds like dandelions and clover so your grass, not the weeds, fills in the lawn.
Crabgrass Pre-Emergent
Applied in early spring before crabgrass sprouts, pre-emergent helps stop it before it takes over your lawn in summer.
Grub Control
Grubs feed on grass roots and can leave brown, dead patches. Grub control protects the roots before the damage shows.
Residential and Commercial Lawns
We treat home lawns of every size, plus commercial properties: business lots, office grounds and HOA common areas. Pair treatments with our weekly mowing for one crew handling your whole lawn.
Seasonal Timing
Treatments follow the seasons: pre-emergent and fertilizer in early spring, weed control as weeds appear, grub control ahead of late-summer damage, and fall feeding to help your lawn recover. Want a thicker lawn? Ask about our aeration and overseeding, offered separately in spring and fall.

Lawn Treatment FAQs
Do you offer lawn treatments for businesses?
Yes. We treat commercial properties as well as homes, including business lots, office grounds and HOA common areas across St. Charles County.
When should crabgrass pre-emergent go down?
Pre-emergent works best in early spring, before soil warms and crabgrass seeds sprout. Once crabgrass is up, pre-emergent won't stop it, so early timing matters.
Can you get rid of the weeds already in my lawn?
Yes. Our weed control targets broadleaf weeds like dandelions and clover that are already growing, and we can recheck problem areas through the season.
How do I know if I have grubs?
Brown patches that peel back like loose carpet, or birds and animals digging in the lawn, are common signs. Grub control is usually applied before the damage shows, so ask us about it in your quote.
Is the person treating my lawn licensed?
Yes. Treatments are handled by a licensed, certified applicator on our staff, and we're fully insured.
