Get matched with top weed maintenance pros in Johnston, IA

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.

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.

It usually takes between two weeks and a month for weeds to fully die off after you spray them with herbicide, but they will start to wilt within the first week. Different weed sprays produce different results, with some working more quickly and effectively than others. Similarly, some weeds are killed more easily than others. Consult your weed removal pro for an exact timeline based on their weed removal method.

Weeds may grow back when pulled out if the root is not completely removed. Invasive weeds can regrow from just a small portion of remaining root, so using a weed-pulling tool can help ensure you remove the entire root. Weeds may grow back faster if roots aren’t fully removed, and incomplete removal could cause them to spread as well.
