Care Guide

Watering

Water regularly during active spring growth; reduce slightly in summer when the plant is semi-dormant.

Fertilization

Apply a balanced, slow-release organic fertilizer as new foliage emerges.. Fertilize lightly only during the active growing season in early spring.

Crushed Eggshells:Wash, dry, and finely crush eggshells, then sprinkle them around the base of the plant. This provides a gentle calcium boost and helps maintain the neutral to slightly alkaline soil pH that hellebores prefer. Avoid using unwashed shells to prevent odors.
Pruning
  • Cut back old, tattered, or diseased evergreen leaves in late winter just as new flower stalks begin to emerge;
  • This practice makes the flowers more visible and reduces the risk of fungal diseases like Hellebore black spot;
  • Deadhead spent flowers in late spring if self-seeding is not desired;
  • Always wear gloves when pruning to protect skin from the irritating sap.
