A garden spade is a tool primarily used for digging and moving soil. It consists of a flat, rectangular blade attached to a long handle. Garden spades come in different sizes and shapes, with some having pointed tips while others have flat tips. In gardening, a spade is used for tasks such as digging trenches for planting, turning soil, and cutting through roots. It can also be used for edging and shaping garden beds. When using a garden spade, it is important to maintain proper posture to avoid injury to the back, shoulders, and arms.
