The best time to split or divide hostas is in early spring as new growth begins to emerge, when the "eyes" or shoots are just poking through the soil. Dividing at this time allows the plants to recover quickly and put on new growth in the same season. Fall, as growth begins to slow down, is also a good time to divide, provided the divisions are well watered and mulched to protect from winter freeze-thaw cycles. Splitting can be done anytime from spring to late summer, but spring and early fall are ideal for the health and vigor of the plant.

Additional tips include:

  • When dividing, make sure each section has at least 2-3 shoots ("points" or "noses") and a good portion of the root system.
  • Use clean, sharp tools like a garden knife or spade.
  • Avoid dividing when the plant is blooming or too close to frost.
  • Mulching late summer divisions helps protect them through winter.
