About This Service

Professional Spring Fertilizer & Weed Control in Olathe & Johnson County KS

What you do in spring sets up your lawn for the whole year. The single most important step is stopping crabgrass before it starts and that window is narrow. Our spring service puts down a pre-emergent barrier at the right soil temperature to block crabgrass and other grassy weeds, pairs it with a light feeding to green up your fescue and bluegrass, and spot-treats the dandelions, clover, and henbit that pop up as it warms. It’s the foundation of a thick, weed-resistant lawn and it’s backed by our satisfaction guarantee.

Timed to Soil Temperature

Pre-emergent has to go down before crabgrass germinates around 55°F soil, typically late March to mid-April here. We watch the soil temps and hit the window, so you’re not chasing crabgrass all summer.

Pre-Emergent + Broadleaf

We stop grassy weeds like crabgrass and foxtail before they start, then knock out broadleaf weeds dandelions, clover, henbit as they emerge.

Light Spring Feeding, Done Right

We give your lawn a gentle green-up not a heavy shot of nitrogen. Feeding too hard in spring pushes weak top growth before the roots are ready, so we feed light now and save the big feedings for fall.

Environmentally Friendly Products

We use professional-grade, environmentally friendly products applied at label rates by licensed, certified applicators safe for your family and pets.

When should pre-emergent (crabgrass preventer) be applied in Kansas?

Before crabgrass germinates when soil temperatures approach 55°F, which in Johnson County usually falls in late March to mid-April. The window is narrow: put it down too late and crabgrass breaks through, and you’ll be fighting it with post-emergent all summer. We monitor soil temps and time your first application precisely.

A light early-spring feeding is all your cool-season lawn needs to green up. Heavy nitrogen too early pushes weak top growth before the roots are ready, which stresses the grass and feeds weeds and disease. The most important feedings come in fall, when fescue and bluegrass do most of their root growth, so we feed light in spring and load up in fall.

With a post-emergent broadleaf treatment applied while the weeds are actively growing in spring. We spot-treat dandelions, clover, henbit, and chickweed rather than blanket-spraying the whole lawn it uses less product and is more effective on the weeds that are actually there.

Yes. Pulling doesn’t stop the thousands of crabgrass seeds waiting in the soil to germinate once it warms up. Pre-emergent creates a barrier that stops them before they sprout and paired with a thick, well-fed lawn, it’s the most effective long-term weed prevention there is.

Just let us know. If weeds show up between your scheduled rounds, we’ll come back and spot-treat at no extra charge for program customers, and our program is backed by a satisfaction guarantee. We want your lawn looking right, not just treated on a schedule.

Spring pre-emergent and weed control is the critical first step, but a thick, weed-resistant lawn needs feeding and care through the whole season especially the important fall feedings. This spring service is the first stage of our full 7-Stage fertilizer and weed control program, which we can set up for you.
