Weed Services FAQs, answered by experts

Weed control applications usually cost around $100 each for a standard-size yard, and most professionals charge between $30 and $60 per hour for manual weed removal. Your total is affected most by the size of the weeded area. Some weed service companies offer weed control treatments, selective herbicide spraying, and manual removal and upkeep as part of a package, costing around $600 annually. You might pay less if you hire the same company for other lawn services, like flower bed upkeep, aeration, overseeding, and pesticide application.

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?

Pulling weeds once per month is typically often enough to keep most weeds at bay. But in general, it's best to pull weeds as soon as you spot them to prevent deep root growth and slow their spread. To make it easier, plan your weed pulling after rain or after the sprinklers run so the soil will be nice and wet and the weeds will be easier to pull. If you notice moss accompanying weeds, make a plan to remove the moss immediately to prevent damage.

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.

Ultimately, pulling weeds vs. spraying them depends on what’s happening in your yard and your personal preferences. Manual weed removal doesn’t introduce any chemicals into your landscape, targets specific problematic plants, produces immediate results, can be free if you go the DIY route, and is inexpensive with a weed service if you only have a handful of weeds. On the other hand, spraying is often preferable for severe weed infestations and situations involving difficult-to-pull weeds because it treats multiple weeds at once, is usually more effective long-term, is less time-consuming, and costs less when done by a pro.
