Fertilization

Apply balanced liquid feed every 2 weeks. Use nitrogen-rich diluted feed to support leafy growth during early development

Eggshell powder topdressing:Crush dried eggshells into fine powder; sprinkle lightly on soil surface and water in to release calcium gradually without causing nutrient buildup
Pruning
  • Harvest outer mature leaves regularly to encourage continuous new growth from the center
  • Remove bolting stems promptly to extend leaf production before seed set
