As a time-saver for you and a lifesaver for plants, spread a layer of shredded bark, chopped leaves, compost, or another material over the soil between plants—nature's way of recycling! A 2- to 3-inch layer of mulch is one of the best multitasking materials for gardens, including beds and containers. Mulch conserves soil moisture, blocks weeds, insulates soil and plant roots from extreme temperatures, prevents erosion, and attracts earthworms (nature's soil builders).
