A Propagation Tray is a gardening tool designed to help grow new plants from seeds or cuttings. It typically consists of a shallow, rectangular container with multiple small cells or compartments. These cells hold soil and provide a controlled environment for seedlings to develop roots and grow strong before being transplanted into larger pots or the garden. Propagation trays are often made from plastic or biodegradable materials and can come with a clear lid to maintain humidity. They are commonly used by both amateur and professional gardeners to efficiently start a variety of plants, including flowers, vegetables, and herbs.
