Keep Your Medicine Park Lawn & Yard Weed Free

Fighting Crabgrass in Mountain Lawns

Crabgrass is relentless in Southwest Oklahoma, and Medicine Park is no exception. This low-growing summer weed spreads rapidly from a central root, creating star-shaped patches that quickly overtake thin or neglected turf. It thrives in hot, sunny spots—especially along driveways, walkways, and anywhere your grass is sparse or stressed from poor soil conditions common in rocky terrain.

The challenge with crabgrass is that it’s an annual that dies off each winter but leaves behind thousands of seeds ready to germinate the following spring. Our strategy focuses on prevention first: we apply pre-emergent herbicides in early spring that create a barrier in the soil, stopping seeds before they sprout. For any crabgrass that manages to break through, we follow up with post-emergent spot treatments during the growing season. This two-part approach helps break the cycle and gives your lawn a chance to thicken up naturally.

Controlling Nutsedge (That’s Not Actually Grass)

If you’ve noticed bright green, shiny plants growing faster than your lawn and poking up above the mower line just days after cutting, you’re dealing with nutsedge. Many people call it “nutgrass,” but it’s actually a sedge—a completely different plant with triangular stems and an aggressive growth habit that outpaces regular turf.

Both yellow and purple nutsedge are common problems around Medicine Park, and they’re notoriously difficult to control because of their underground tuber systems. Pulling them out doesn’t work—the tubers just send up new shoots. We use specialized sedge herbicides that target the plant’s unique biology without harming your grass, combined with follow-up treatments that weaken the underground network over time. With consistent treatment and proper lawn care practices, we can gradually reduce nutsedge and prevent it from bouncing back.

Eliminating Broadleaf Weeds

Broadleaf weeds are the ones that clearly don’t belong in your lawn—they have wide, flat leaves instead of grass blades, and many produce visible flowers or seed heads. Around Medicine Park, we commonly see dandelions, clover, chickweed, plantain, spurge, oxalis, and wild garlic or onion taking over lawns.

These invaders fall into two categories: annuals that live for one season and perennials with established root systems that return year after year. Both types compete with your grass for water, nutrients, and space, gradually thinning out your turf and creating bare patches that invite even more weeds. We use selective herbicides designed to kill broadleaf plants without damaging your grass, applied at optimal times based on weather and weed growth stages. Combined with a solid fertilization plan, this approach strengthens your turf so it can naturally crowd out invaders.

Managing Wild Violets and Shade-Loving Weeds

Wild violets might look harmless—some people even appreciate their purple blooms—but in a lawn, they’re aggressive colonizers. They spread through both seeds and underground runners, forming thick mats that suffocate grass, particularly in shaded areas under trees or on the north side of structures where turf naturally struggles.

In Medicine Park, where many properties have significant tree cover and shade from surrounding terrain, wild violets can explode after wet springs. They’re also extremely resistant to standard homeowner weed killers because of their waxy leaf coating and deep root systems. We use professional-grade treatments applied during strategic windows—usually fall or cooler weather—when the plants are most vulnerable. This isn’t a one-treatment fix, but with persistence we can push them back and help your grass reclaim those shaded areas.
