Tropical Growing Tips for Culantro

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
  • Root rot and damping off: Plants die in poorly drained or waterlogged soil

Pro Tips

  • Mix organic compost into soil prior to planting; feed monthly with a liquid nitrogen fertiliser to encourage fresh leafy growth
  • Apply a light layer of organic mulch around the plant base to retain moisture and keep roots cool
  • Pinch off central flower stalks as soon as they emerge to prevent bolting and prolong leaf production
