Gardeners who skip this step may miss out on a powerful tool supporting long-term plant health. Before your next planting season, look at what living mulch can do for your spring garden.

Living mulch helps block sunlight from reaching the soil surface, making it harder for weed seeds to sprout and grow. With fewer weeds popping up, gardeners spend less time pulling them out by hand. Unlike bare soil or synthetic mulch, living mulch keeps growing and shading the ground. This active cover creates a natural weed barrier, reducing the need for chemicals or constant weeding. That means less work and a cleaner-looking garden.
