The answer to 'weed control not growing' is that there are several common causes, including incorrect application of weed control products, competition from healthy plants, and environmental factors like soil type or moisture levels. Symptoms may include patchy or uneven weed growth, or a complete lack of weeds in certain areas.
To address this issue, first check the application instructions for any weed control products you've used and ensure you followed them correctly. Next, evaluate the overall health and vigor of your lawn or garden plants - healthy, thriving plants can outcompete weeds. Finally, consider factors like soil composition, sunlight, and moisture levels, and make adjustments as needed. In some cases, you may need to reapply weed control products or consult a professional landscaper for more advanced solutions.
