Monthly care calendar

Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.

January
  • Pruning: If it was not done in autumn, cut the dry stems from the previous year at a level close to the soil.
  • General care: Compost or leaf mold can be spread around the roots as mulch.
  • Pests & diseases: Do not disturb the roots sleeping underground.
  • Frost risk: Its roots are very hardy; no protection is needed.
February
  • Fertilizing: Get ready for an application of slow-release balanced fertilizer (e.g. NPK 10-10-10).
  • Pruning: If cleanup has not been done, now is the last chance.
  • General care: This is one of the best times to propagate by division (it can also be done in March).
  • Pests & diseases: Be prepared to protect the newly emerging shoots from snails and slugs.
  • Frost risk: Newly emerging shoots may be sensitive to frost.
March
  • Watering: If the soil begins to dry, 10-15 L/week; reduce if there is rain.
  • Fertilizing: Apply a balanced fertilizer or well-rotted organic fertilizer once when it wakes from dormancy.
  • Plant protection: Check the newly emerging fresh leaves for snails and slugs.
  • General care: If the roots of the plant are severely root-bound, this is the time to lift the plant, divide the roots, propagate and replant.
