Weed Control in Lehigh Valley: A Homeowner's Guide
Weed control is one of the most common reasons Lehigh Valley homeowners search for professional lawn care. The right approach isn't about spraying more — it's about using the right products at the right time and building a lawn thick enough to crowd weeds out naturally.
This article is part of our Lawn Care Services in Lehigh Valley, PA series. For the full picture of what your lawn needs, start with that guide.
Common Weeds in Lehigh Valley Lawns
Eastern Pennsylvania lawns face a variety of broadleaf and grassy weeds throughout the growing season:
Broadleaf Weeds
- Dandelions
- Clover
- Wild violet
- Ground ivy (creeping Charlie)
- Plantain
- Spurge
Grassy Weeds
- Crabgrass
- Nutsedge
- Creeping bentgrass
- Annual bluegrass (Poa annua)
- Orchardgrass
- Tall fescue clumps
Different weeds emerge at different times of the year, which is why effective weed control requires multiple treatments throughout the growing season — not a single application.
Pre-Emergent vs. Post-Emergent Weed Control
Pre-Emergent
Creates a soil barrier that prevents weed seeds from germinating. Applied before weeds appear.
Targets: Crabgrass, annual bluegrass, other annual grassy weeds
Post-Emergent
Controls weeds that are already actively growing in the lawn. Applied after weeds emerge.
Targets: Dandelions, clover, wild violet, ground ivy, nutsedge
Hard-to-Control Weeds in the Lehigh Valley
Some weeds require specialized products and precise timing:
- Creeping Charlie / Ground Ivy — Waxy leaves resist standard herbicides; best treated in late fall
- Wild Violets — Tough, waxy leaves; require surfactants and fall timing
- Nutsedge — Fast-growing, aggressive; requires specific herbicide
- Creeping Bentgrass — Invasive grassy weed requiring specialized treatment

The Secret to Long-Term Weed Control: A Thick Lawn
Killing weeds is only half the battle. The best long-term weed control strategy is building a lawn so thick that weeds can't find space to grow.
A dense lawn naturally suppresses weeds by:
- Blocking sunlight from reaching weed seeds on the soil surface
- Competing for water, nutrients, and space
- Crowding out weed seedlings before they establish
This is why Golden Green combines weed control with fertilization, aeration, and overseeding — weed control alone can't produce a healthy lawn.
Golden Green's Approach to Weed Control
Our 6-Step Lawn Care Program includes:
- Properly timed pre-emergent crabgrass control in early spring
- Post-emergent broadleaf weed control throughout the growing season

- Free service calls if weeds appear between treatments
