A planter is a container used for growing plants, flowers, or vegetables. It can be made from various materials, including plastic, wood, ceramic, or metal. Planters come in different shapes and sizes, allowing gardeners to choose the best fit for their space, whether it's a small balcony or a large garden. Planters can be placed indoors or outdoors and often have drainage holes to prevent water from accumulating. They are essential for container gardening, which allows people to cultivate plants without traditional garden beds. Popular types of planters include hanging planters, window boxes, and raised beds.
