A tiller is a garden tool or machine used to break up and turn over soil, making it easier to plant and improving soil aeration. Tilling is an important step in preparing a garden bed, as it loosens compacted soil, incorporates organic material, and helps to mix nutrients evenly. There are manual tillers for small gardens and larger, motorized versions for more extensive work. Tilling can help create better conditions for planting but should be done carefully to avoid soil erosion.
