How to Start It
★ Recommended for beginners
Break a bulb into cloves and plant the largest 3–5cm deep, pointy-end up, about 15cm apart in autumn. Each clove grows into a whole new bulb by the following summer.
Garlic is grown from cloves, not seed: split a bulb and plant the biggest cloves pointy-end up in autumn. It needs a spell of winter cold (vernalisation) to split a single clove into a full bulb, so autumn planting beats spring. Plant disease-free 'seed garlic', not supermarket bulbs, for the best results.
When To Start
Garlic likes cool weather. Sow it in early spring, as soon as the ground can be worked.

Planting & Sprouting
Growing Tips
- 1Split a bulb into cloves at planting and set each one pointy-end up, 5 cm deep.
- 2Plant in fall so roots establish before winter, then mulch heavily.
- 3On hardneck types, snip the curling scapes in early summer — it redirects energy into the bulb (and the scapes are delicious).

How to Harvest
- 1Stop watering a week or two before harvest.
