How To Grow Garlic

Garlic is part of the onion family. Perhaps surprisingly for a vegetable associated so much with the Mediterranean lifestyle and cuisine, growing garlic is remarkably easy. In fact, garlic is hardier and more reliable to grow than onions.

After successful germination in early winter or spring, there is often very little left to do but hoe around the growing plants until harvest.

  • From early October to late March
  • Planting depth: clove tips pushed into soil, tips 2 cm below surface (3 cm for elephant garlic)
  • Planting spacing: 20 cm between cloves, 30 cm between rows


  • June – August
  • Hang to dry, and store in a cool and dry place

The traditional saying is to plant garlic on the shortest day of the year for harvesting on the longest day. I have had success planting garlic in October at the same time as my onions for over wintering. Spring is the latest time recommended to plant garlic.

I have found that birds sometimes lift my freshly planted garlic bulbs out of the soil to investigate whether they are edible. I now cover my garlic bed with a net until the bulbs have sprouted. Birds seem to leave them alone once this has happened so the net can be removed.

During spring, garlic should be watered during dry weather. This will help the plants grow strong and tall.

Towards early summer, garlic is best grown hard. Apart from very hot weather, the flavour of garlic is improved with sun and dry soil. Having said this, I do occasionally water my garlic as my soil is particularly sandy and dry. Garlic can grow to over 50 centimetres high. It is easy to tell when garlic is ready for harvesting as the leaves turn yellow and fall over.
