Rhizomes are a special type of plant stem that grows horizontally underground, from which new plants can sprout up and grow roots down. Think of it like a natural way that plants spread and multiply themselves. Gardeners and landscapers work with rhizomes when they want to either encourage plant growth (like with ornamental grasses or bamboo) or control spreading plants that might take over a garden. Working with rhizomes is an important skill in gardening because it affects how you plant, divide, and maintain many popular garden plants like iris, ginger, and bamboo.
