Growing garlic in home gardens

Quick facts

  • Garlic grows best in well-drained, moisture-retentive soil with pH between 6.0 and 7.0.
  • Plant cloves in the fall, usually one or two weeks after the first killing frost.
  • Unless you control weeds early, they can easily overtake young garlic plants.
  • Insects are not a major problem with garlic, although onion maggot is a potential pest.
  • Depending on variety and climate zone, harvest garlic between late June and late July.
