Garlic is a hardy, sun-loving bulbous vegetable from the onion family, grown for its pungent cloves used in cooking. It’s easy to grow in a warm, well-drained spot and needs minimal fuss – plant individual cloves and they will develop into full bulbs by the following summer. Most garlic varieties require a cold spell over winter to form good bulbs, so in the UK they are generally planted in autumn. There are two main types of garlic: hardneck and softneck. Hardneck types produce flower stalks (scapes) which should be removed, and their bulbs have fewer but larger cloves (they store for around 4–6 months). Softneck types have more, smaller cloves and rarely bolt; they also store for longer, often up to a year.

Plant garlic cloves in autumn for a plentiful summer harvest. The plants establish roots over winter, yielding larger bulbs.

  1. 01

    Prepare Soil

    early October to late October UK average · set your town for your exact dates

    Ensure the soil is well-draining to prevent winter rot. Dig in compost or well-rotted manure to improve structure, ideally early October to late October. Work the soil to a fine tilth and remove any weeds.

  2. 02

    Plant Cloves

    late October to early November UK average · set your town for your exact dates

    Plant individual cloves with the tips just showing above the soil, spaced apart in rows apart. Firm the soil gently around them to eliminate air pockets. This is best done late October to early November.

  3. 03

    Weed and Mulch

    early November to mid-November UK average · set your town for your exact dates

    Keep the area weed-free, as garlic competes poorly for light and nutrients. Apply a mulch of straw or compost to suppress weeds and retain moisture. Do this early November to mid-November after planting.

  4. 04

    Remove Scapes

    late April to late May UK average · set your town for your exact dates

    If growing hardneck varieties, snap off the curly flower scapes in late spring to direct energy into bulb growth. Do this late April to late May when scapes appear.

  5. 05

    Harvest Bulbs

    late June to late July UK average · set your town for your exact dates

    Lift bulbs when the foliage starts to yellow and fall over, typically late June to late July. Use a fork to loosen the soil and avoid damaging the bulbs.

  6. 06

    Cure and Store

    late July to mid-August UK average · set your town for your exact dates

    Dry the harvested bulbs in a well-ventilated, shaded spot for 2–3 weeks until the skins are papery. Trim the roots and foliage before storing in a cool, dry place. Start curing late July to mid-August after harvest.

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
