The answer to 'weed control not growing' is that there can be several common causes, including improper weed control methods, inadequate soil conditions, or incorrect timing of application. Weeds may not be growing due to issues like poor soil fertility, excessive shade, or competition from other plants.
To troubleshoot, start by evaluating the type of weed control product you're using and ensuring it's appropriate for the weeds in your lawn or garden. Make sure to follow the product instructions carefully, including applying at the right time of year. You should also check the soil pH and nutrient levels, and consider aerating or amending the soil if needed to create optimal growing conditions.
