How to Grow Garlic

Garlic is a fall-planted crop in most of the US. A raised bed is a good home if it drains. Plant cloves in autumn, mulch, ignore them most of the winter, then water steadily in spring until harvest.

Soil requirements

  • Do not plant in a soggy closed-bottom bed. Rot is the winter killer.

Watering

  • Winter precipitation often does the work. In dry Western winters, occasional water may be needed if the bed is bone dry.
  • Stop heavy watering when leaves yellow in early summer.

Sunlight

Full sun in spring. It can share a bed that will later hold tomatoes after harvest.

Planting

  • Break bulbs into cloves just before planting. Softneck vs hardneck is a climate and kitchen choice.
  • Mulch after the ground cools. Pull mulch back in spring if it stays too wet.

Spacing

  • 4–6 inches in the row, 8–12 inches between rows if you use rows.

Common problems

  • Rot

    Poor drainage or planting grocery garlic treated to not sprout well.

  • Small bulbs

    Late planting, crowding, or stopping water too early in spring.

Helpful tools

  • Mulch
  • A dry, airy place to cure

Frequently asked questions

Can I plant grocery-store garlic?

Sometimes. It may be a type unsuited to your climate or treated against sprouting. Seed garlic from a grower is the more reliable path.
