A seedling tray is a shallow container designed for starting seeds and growing young plants. It typically has multiple small compartments, allowing gardeners to plant several seeds in a compact space. These trays are often made from plastic or biodegradable materials and can be used indoors or outdoors. Using a seedling tray helps ensure that each seedling has enough space to grow while also making it easier to manage and transport them. Once the seedlings are strong enough, they can be transplanted into larger pots or directly into the garden, promoting healthy growth and development.
