A rototiller is a gardening tool used to prepare soil for planting. It features rotating blades or tines that dig into the ground, breaking up compacted soil and mixing in organic matter like compost. This process helps improve soil aeration and drainage, making it easier for plants to grow. Rototillers come in various sizes, from small, handheld models to larger, tractor-mounted versions. They are especially useful for turning over garden beds, creating rows for planting, and controlling weeds. Using a rototiller can save time and effort compared to manual tilling with a shovel or hoe.
