A propagation method in which a mature perennial plant is separated into smaller sections, each containing roots and growing points, to create multiple new plants.
Many perennial plants naturally grow in expanding clumps over time. As the clump becomes larger, it can be split into smaller pieces and replanted elsewhere.
Because each division already contains an established root system and active shoots, the new plants typically establish much faster than plants grown from seed. This makes division one of the simplest and most reliable ways to multiply perennial plants.
Division also helps reduce overcrowding and can restore vigor to older plants that have become crowded or less productive.
Division allows gardeners to create additional plants at no cost while maintaining the same characteristics as the parent plant. It is also an effective way to rejuvenate mature perennials, improve flowering, and manage plants that have outgrown their space.
