Weed Control Services in Concord NH

Get rid of weeds without killing your lawn

Dandelions, clover, crabgrass, and creeping charlie are the biggest offenders in central New Hampshire. They spread fast in summer and most homeowners end up pulling them by hand or spraying products that burn the grass along with the weeds.

We use selective herbicides that target weeds without damaging the surrounding turf. Timing matters. Crabgrass needs pre-emergent treatment in early spring before it germinates. Broadleaf weeds respond best to post-emergent application in late spring and early fall when they are actively growing.

Common weeds we treat

  • Crabgrass: Pre-emergent barrier in early spring prevents germination. Post-emergent spot treatment for breakthrough.
  • Dandelions: Broadleaf herbicide application in spring and fall. Targets the root system, not just the top growth.
  • Clover and creeping charlie: Persistent broadleaf weeds that spread through runners. Requires targeted treatment and improved lawn density.
  • Plantain and thistle: Common in compacted soils. Often paired with aeration to address the root cause.

Weed control works best as part of a full lawn care program. A thick, healthy lawn is the best defense against weeds coming back. We typically combine weed treatment with our fertilization program for the best results.

Common Questions

Frequently Asked Questions

We treat broadleaf weeds including dandelions, clover, plantain, and chickweed, as well as grassy weeds like crabgrass. Treatment type depends on what you have and when in the season we are treating.

Typically two to three applications: a pre-emergent in early spring to prevent crabgrass before it germinates, a broadleaf treatment in late spring or early summer, and a follow-up if needed in fall. Persistent weeds may require additional visits.

Yes, once the treated area has dried. We follow all label requirements for re-entry intervals. We'll let you know when it is safe to be back on the lawn after each application.

Pre-emergent goes down in early spring before soil temperatures hit 50 degrees. Broadleaf treatments are most effective in late spring and early fall when weeds are actively growing. Timing matters more than most people realize.

Yes. Pre-emergent crabgrass control is part of our program. The key is timing: it needs to go down before crabgrass germinates in spring. Once crabgrass is established, prevention does not work and control options are more limited.

Yes. Kyle Poirier holds NH Pesticide License NHPC-914 and is fully insured for all herbicide and pesticide applications in New Hampshire.
