Get matched with top weed maintenance pros in Richfield, WI

If you have a lot of tree roots in your yard or have experienced issues in the past, you should use tree root killer every six months to prevent roots from infiltrating your pipes. If you have an active invasion and aren’t seeing results, check the instructions on the bottle to see how often you can use it in a short period of mine.

The best way to prevent weeds is to use polymeric sand, which hardens and blocks weed growth when activated with water. If you're using regular sand, you'll need to refill and compact it more often. Keeping the surface clean and free of debris can also help prevent weed seeds from settling in the joints.

Whether a one-time spray treatment to control mosquitoes is enough depends on multiple factors. Often, you’ll notice a big difference after one application. However, mosquitoes are likely to return if you don't reduce attractive standing water habitats. This usually takes four to eight weeks if it’s still prime mosquito season.

The best time to hire a weed service company is in the early spring. This allows them to apply a pre-emergent weed killer that stops weeds from taking root, making maintenance for the rest of the season much easier. Following the initial spring application, a monthly service through the summer and early fall is a good idea for ongoing weed control. These regular treatments, combined with manual removal or spot treatment, should be sufficient to maintain a weed-free yard. Alternatively, you can hire a professional in the fall for the following year, as some companies may offer better rates on contracts signed before the busy spring season.
