How can I effectively prepare my garden beds for planting by tilling the soil?

To effectively prepare your garden beds for planting by tilling the soil, start by removing any weeds or debris. Then, use a tiller to break up the soil and create a loose, aerated bed for planting. Avoid over-tilling, as this can damage the soil structure. Finally, add compost or other organic matter to improve soil fertility before planting your crops.
