Garlic · Allium sativum

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 early spring for a later summer harvest. This method is useful if autumn planting was missed.

  1. 01

    Prepare Soil

    25 Mar to 9 Apr

    Ensure the soil is well-draining and fertile. Dig in compost or well-rotted manure to improve structure, ideally 25th March - 9th April. Remove any weeds and break up clods.

  2. 02

    Plant Cloves

    9 Apr to 25 Apr

    Plant individual cloves with the tips just showing above the soil, spaced apart in rows apart. Firm the soil gently around them. This is best done 9th April - 25th April.

  3. 03

    Weed and Water

    24 Apr to 15 Aug

    Keep the area weed-free and water during dry spells to ensure good growth. Garlic has shallow roots and benefits from consistent moisture. Maintain this 24th April - 15th August after planting.

  4. 04

    Remove Scapes

    16 Jul to 15 Aug

    If growing hardneck varieties, snap off the curly flower scapes in late spring to direct energy into bulb growth. Do this 16th July - 15th August when scapes appear.

  5. 05

    Harvest Bulbs

    15 Aug to 14 Sept

    Lift bulbs when the foliage starts to yellow and fall over, typically 15th August - 14th September. Use a fork to loosen the soil and avoid damaging the bulbs.

  6. 06

    Cure and Store

    30 Aug to 6 Sept

    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 30th August - 6th September after harvest.

Plants to avoid

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.
