Care Guide

Watering

Water deeply when the top 2–3 cm of soil is fully dry

Fertilization

Diluted low-nitrogen liquid feed once monthly. Use a balanced, diluted fertilizer to support healthy foliage growth without promoting leggy stems

Eggshell powder topdressing:Crush dried eggshells into fine powder; lightly mix into the top 1 cm of soil to boost calcium levels and improve drainage; limit application to 1–2 tablespoons per plant to avoid soil alkalinity
Pruning
  • Trim back leggy stems in early spring to encourage compact, bushy growth
  • Deadhead spent flower spikes to promote prolonged blooming and redirect energy to foliage growth
  • Remove any dead or damaged foliage throughout the growing season to maintain plant health
