To keep your garden free from weeds, it's best to weed regularly. The frequency of weeding depends on the growth rate of weeds in your area and the size of your garden. As a general guideline, aim to weed your garden at least once a week during the growing season. However, be sure to monitor your garden regularly and remove any weeds as soon as you spot them. By staying on top of weed growth and removing them promptly, you can prevent them from competing with your plants for nutrients and space.
