A garden tiller is a tool used to prepare soil for planting by breaking it up and mixing in organic matter. It typically features rotating blades or tines that dig into the ground, making it easier to aerate and loosen compacted soil. This process helps improve drainage and nutrient absorption for plants. Garden tillers come in various sizes, from small, handheld models to larger, motorized versions. They are especially useful for gardeners who want to cultivate larger areas or improve soil quality in their gardens. Using a tiller can save time and effort compared to manual digging with a shovel or hoe.
