Here are some key points to remember about propagating plants by division.

• Division is a propagation method where a plant is divided and the parts are grown on.
• It is used to increase the numbers of many herbaceous perennials.
• Each section of a divided plant must have shoots and roots.
• The division method depends on the growth habit of the plant.
• Divisions can be made using:
  • crowns, for example flax cultivars
  • tubers and tuberous roots, for example potatoes and dahlias
  • rhizomes, for example flag iris
  • suckers, for example raspberries
  • bulbs and corms, for example daffodils and gladioli
  • offsets, for example Agave species
  • pseudobulbs, for example orchids
  • runners, for example strawberries.
