Care Guide

Watering

Keep soil evenly moist but not waterlogged to support active growth and flowering

Fertilization

Diluted balanced liquid feed once every 4 weeks. Use a low-nitrogen fertilizer to promote flower production over leaf growth

Eggshell powder topdress:Crush dried eggshells to fine powder; sprinkle lightly on soil surface to boost calcium levels and adjust pH to slightly alkaline, supporting healthy stem and flower development
Pruning
  • Deadhead spent blooms promptly to encourage prolonged flowering throughout the season
  • Trim back leggy stems in early spring to maintain a compact, mat-forming growth habit
  • Remove any dead or damaged foliage in late winter to promote new, healthy growth in spring
