Weed Services FAQs, answered by experts

Glyphosate and other non-selective herbicides can kill orchard grass, but they will also kill the surrounding plants. Also, not all areas allow the use of glyphosate due to its environmental impact—which the EPA describes as a "potential risk to terrestrial and aquatic plants and birds, and low toxicity to honeybees." Consider mechanical removal to target the plants specifically.

A spot herbicide for weed control is effective at killing crabgrass and not grass, but it depends on the type of herbicide. Always check the label to ensure that your herbicide is safe for grass but tough on crabgrass. Overall, spot treatment is ideal because it puts fewer herbicides into the soil, which can damage the soil. If you’re wanting a natural remedy to crabgrass that also won’t harm surrounding grass, you can also hand-remove crabgrass or even pour boiling water or 5% vinegar over crabgrass as a spot treatment.

There are a few things you should ask a weed service company before hiring to ensure you’re choosing the best professional for the job:

  • How often will you apply herbicides?

  • Do you include any spot treatments or manual weed removal in your pricing?

  • Do you offer pet-safe and kid-safe herbicides?

  • What other lawn services can you provide?

  • Do you offer any kind of guarantee for the work performed?

  • Are you properly licensed and fully insured?

  • Do you have any customer references I could speak with?

Each type of weed comes with its own control methods, but stopping the seed spread is the first step. Grazing, mowing, and hand pulling can slow the invasion. In some cases, selective herbicide is necessary to stop a persistent weed from overtaking an area.

The best time to fight crabgrass with pre-emergent herbicide is when forsythias tend to bloom. In the mid-Atlantic region, this is usually between April and May. Even if you're late to apply the herbicide, it’s effective as long as the crabgrass plant has fewer than five leaves.
