Arid / Semi-Arid Growing Tips for Liquorice

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
  • Snails and Slugs: Severe in winter on dormant crowns

Pro Tips

  • Top-dress with organic compost or well-rotted manure in early spring; as a legume, it fixes its own nitrogen

  • Cut dead top foliage back to ground level in late autumn after stems turn brown and die off
