O'hara pest control logo

Weed control for lawns is the difference between a yard that looks “fine from the street” and one that stays thick, clean, and consistently green up close. In South Florida, weeds don’t wait for permission—rain, heat, and stressed turf give them an opening fast.

O’Hara Pest Control helps homeowners and property managers take that opening away with a structured plan that combines targeted weed control, a smart fertilization strategy, seasonal scheduling, and recurring service visits that keep weeds from creeping back.

What’s Included in Our Weed Control Program

Our weed control program is designed to reduce active weeds now and limit re-growth over time. Depending on lawn condition and what’s currently active, your plan may include:

  • Targeted post-emergent weed control for existing broadleaf and grassy weeds (as appropriate)

  • Pre-emergent applications to help prevent new weeds from sprouting

  • Spot treatments for stubborn areas (driveways, edges, thin turf zones)

  • Monitoring for invasive grasses and aggressive weed varieties

  • Program-based fertilization support to help turf thicken and compete naturally

  • Recurring service schedule to maintain progress through the season

Weed Control for Lawns That Delivers Results (Not Just Quick Knockdown)

Weeds don’t just “show up.” They move in when turf is thin, stressed, or underfed—and South Florida weather can make that happen quickly. Effective weed control for lawns works best as a system:

A seasonal strategy typically focuses on:

  • Treat what’s active
    We identify what’s growing and apply treatments designed to target the weeds present while minimizing stress to your grass.  

  • Prevent what’s next
    Pre-emergent timing matters. When applied correctly, it helps prevent weeds from sprouting and spreading.

  • Strengthen the turf
    Healthy grass crowds out weeds. That’s why we pair weed control with a fertilization strategy that supports turf density and resilience.

If your lawn keeps getting overtaken, it’s time for a real program. Get a free weed control quote today.

Seasonal Lawn Treatments for Weed Prevention Year-Round

In West Palm Beach, weed pressure shifts throughout the year. Different weeds thrive in various conditions, and timing is often where lawns lose ground.

Our seasonal scheduling focuses on:

  • Pre-emergent timing during key weed germination windows

  • Targeted treatments when specific weed types become active

  • Support during rainy periods when weeds spread faster, and turf can struggle

  • Plan adjustments based on what your lawn is showing, not a rigid template

Seasonal planning turns weed control into prevention—not a constant reaction.

Organic vs synthetic: what matters mostOur Process: Inspect → Treat → Maintain

green grass in the yard

Weed control works best when it’s repeatable and tracked. Here’s how we run it:

Inspect

We walk the property and assess weed activity, turf density, stress zones, and areas where weeds commonly reappear (edges, shaded spots, thin turf).

Treat

We apply targeted treatments based on what’s present and what’s likely to emerge next. Treatments are chosen to control weeds while protecting the surrounding lawn.  

Maintain

Recurring service is where lasting results come from. We keep timing consistent, adjust seasonally, and provide follow-up when trouble spots need extra attention.

How Much Does Weed Control for Lawns Cost?

Pricing depends on the factors that actually affect results:

  • Lawn size and turf coverage

  • Weed type and infestation level

  • Turf condition (thin vs thick, stressed vs healthy)

  • Seasonal timing and frequency

  • Property layout (beds, pavers, edges, shaded zones)

We provide clear pricing after we evaluate your lawn and goals.

DIY vs Professional Weed Control: What’s the Real Difference?

DIY weed control often fails for one reason: timing. Store-bought products can help in small situations, but many lawns need consistent scheduling and correct identification to stop repeat outbreaks.

Professional weed control offers:

  • Better accuracy in identifying weeds and choosing treatment

  • Proper timing for pre-emergent and post-emergent applications

  • A recurring plan that prevents re-growth

  • Support that strengthens turf so weeds have less opportunity

If you’ve tried spot treatments and the weeds keep returning, a program usually wins.
