Growing notes

  • Plant in autumn (cold climates) or late autumn/winter (warm climates) — needs cold dormancy to differentiate cloves
  • Hardneck cultivars are more cold-hardy; softneck cultivars suit milder climates and longer storage
  • Always consult a qualified medical or herbal practitioner before medicinal use.

Pet caution: Garlic is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
