The answer to 'how to maintain weed control' is to use a combination of prevention, mechanical removal, and targeted herbicide application. Start by maintaining a healthy, dense lawn that can outcompete weeds. Regularly mow, aerate, and overseed your lawn to create an environment that is less favorable for weeds to grow. When weeds do appear, pull them by hand or use a hoe or cultivator to remove them from the root. For persistent or difficult-to-control weeds, apply a selective herbicide that targets the specific weed type. Always follow the product instructions carefully and apply during the recommended weather conditions.
It's important to be diligent and persistent with your weed control efforts, as weeds can quickly spread and become more difficult to manage if left unchecked. Consider hiring a professional landscaper if you have a large area to maintain or are dealing with a severe weed problem that is challenging to control on your own.
