Broadleaf Weed Control

Iowa's warm, wet springs are about as good as it gets for broadleaf weeds. Dandelions are up before the grass gets going. Creeping Charlie spreads across shaded areas all spring. Thistle comes on heavy in June. Left alone, these weeds compete with your grass for water and nutrients -- and they win.

We apply liquid broadleaf herbicide that's selective -- meaning it kills broadleaf plants and leaves turf grasses alone. The product absorbs through the leaves and moves through the plant's vascular system down to the root. That's why it works better than pulling: you get the root.

Timing matters on both ends of the season. Spring applications work best when weeds are actively growing and taking up product fast. Fall applications -- especially for dandelions -- are often more effective because the plant is pulling energy down into the root to store for winter. Hit it then and you knock out the root entirely.

What We See in These Lawns

Central Iowa lawns deal with a predictable set of weeds -- the same ones show up in Stuart, out toward Earlham and Greenfield, and across Guthrie, Adair, and Madison Counties. Heavy clay soil compacts easily and stays wet in spring, which creates exactly the conditions weeds love. Knowing what you're dealing with matters because timing and product choice differ by species.

  • Dandelions -- the most common. Deep taproot. Spring and fall applications both effective.
  • Creeping Charlie (ground ivy) -- spreads aggressively in shade. Liquid application with a surfactant works well in late spring.
  • Thistle -- tall, spiny, and persistent. Established plants need repeat treatments. Best controlled young.
  • Clover -- spreads in low-nitrogen lawns. Control is part of a broader fertilization plan.
  • Plantain -- wide-leaf, low-growing. Common in compacted soils. Responds well to broadleaf herbicide.
  • Wild violet -- harder to control than most. May need a specialty product and multiple applications.

Weed Control vs. Fertilization

Weed control and fertilization aren't the same thing -- but they work together. Weed control eliminates the competition. Fertilization builds up the turf so it can fill in the gaps those weeds left behind. A lawn that's thick and healthy crowds out weeds naturally over time.

If you're only spraying weeds without feeding the grass, you'll keep having the same problem every year. The weeds come back because the turf isn't dense enough to keep them out. That's the cycle people get stuck in.

Our 8-Step Lawn Care Program addresses both sides: scheduled fertilizer applications timed to the season, plus weed control built into the program. It's the comprehensive approach, and it's what we recommend if you want your lawn to actually improve year over year instead of just getting maintained.

Frequently Asked Questions

How long does it take for weeds to die after treatment?

Most broadleaf weeds show visible damage -- yellowing, wilting, curling -- within 3 to 7 days. Complete browning and death typically takes 2 to 3 weeks. The speed depends on the weed species, the temperature, and how actively the plant is growing. Weeds treated during warm, sunny weather die faster than those treated during cool or cloudy stretches. Don't judge a treatment at day 5 -- give it two to three weeks before deciding if a second application is needed.

Is it safe for kids and pets after the product dries?

Yes. Once the product has dried -- typically 2 to 4 hours after application, depending on temperature and sun -- the lawn is safe for foot traffic from people and pets. We'll let you know when we spray and roughly when it's dry. If it rains within a couple of hours of application, we may need to re-treat since the product gets washed off before it's had a chance to absorb. We'll tell you if that happens.

Will the herbicide kill my grass?

No. The products we use are selective broadleaf herbicides -- they're designed specifically to affect broadleaf plants and not grasses. They work by targeting a biological process that broadleaf plants have and grasses don't. That said, every lawn is different, and some fine fescues and ornamental grasses are more sensitive. If you have unusual grass varieties or groundcover plants you want to protect, tell us before we apply. We'll adjust the application or work around those areas.

How often do I need treatment?

Most lawns benefit from two applications per year: one in spring (late April to May, once weeds are actively growing) and one in fall (late September to October). A single spring application handles a lot of the problem but won't eliminate everything, especially perennials like creeping Charlie that need repeat treatment over time. If you're on our 8-Step Program, weed control is scheduled into the program -- you don't have to think about timing.
