The answer to 'weed control dying' is that there are several common causes for dying weed control, including improper application, weather conditions, and competition from other plants. Symptoms may include patchy, thinning coverage or weeds continuing to grow despite treatment. To address this, you'll need to identify the underlying cause and adjust your approach accordingly.
If the weed control product was not applied correctly, such as using the wrong amount or missing areas, this can lead to ineffective results. Weather conditions like heavy rain or drought can also impact the effectiveness of weed control treatments. Additionally, if weeds are competing with other plants for resources, the weed control may not be able to fully eliminate them.
