Continuous harvest and vitality Regular cutting encourages new growth.

Remove

  • Yellow or dried outer leaves
  • Flower stalks in the second year (to briefly preserve leaf aroma)
  • Infected leaves in case of Septoria fungus

Preserve

  • Heart leaf (central growing point)
  • Young, healthy shoots for photosynthesis

Avoid

  • Clearing the entire plant at once
  • Damaging the heart while cutting

Tools and hygiene

Use clean scissors to prevent the transmission of leaf spot diseases.
