Setup, Compatibility & Care

  1. Planting: Remove the plants from their 9cm pots and place them in a hole slightly larger than the root ball. Ensure the crown is level with the soil surface.
  2. Soil Conditions: These plants demand well-draining soil. If your garden has heavy clay, mix in horticultural grit or sand to improve drainage.
  3. Sunlight: Choose a location that receives at least 6-8 hours of direct sunlight daily.
  4. Watering: Water thoroughly immediately after planting. Once established, they are moderately drought-tolerant, though containers will need regular moisture during dry spells.
  5. Maintenance: Leave the foliage to die back naturally in autumn; this allows the plant to store energy for the following season. You can tidy up by removing dead stems in late winter or early spring.
