Subtropical Growing Tips for Mitsuba

Key Challenges

  • Common Garden Snail: Introduced snail with a tan spiral shell
  • Slugs: Soft-bodied shell-less molluscs that feed at night on seedlings and leafy vegetables
  • Slugs and Snails: Eat young seedlings and tender leaves
  • Downy Mildew: Weakens leaves and can spoil the curd in wet weather

Pro Tips

  • Work rich compost into soil prior to sowing; apply a liquid nitrogen-rich organic fertiliser fortnightly to promote tender leafy growth
  • Apply a light organic straw mulch around plants to preserve root moisture, keep soil cool, and prevent weeds
  • Pinch off early flower buds as soon as they appear to prolong leafy growth and prevent premature bolting
