When to plant Garlic in the UK

Allium sativum

Garlic
Garlic · Allium sativum

Hardy garlic for a sunny, well-drained UK bed. Plant garlic sold for planting in autumn so it gets a cold spell and makes bulbs the following summer. Choose named varieties sold as seed garlic rather than supermarket bulbs. Hardneck types make a flower stem called a scape. Snap it off when it appears. Softneck types rarely make scapes.

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

  1. 01

    Prepare Soil

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

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

  2. 02

    Plant Cloves

    early April to mid-April 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. This is best done early April to mid-April.

  3. 03

    Weed and Water

    early April to mid-August UK average · set your town for your exact dates Dates as each sowing reaches this stage

    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 early April to mid-August after planting.

  4. 04

    Remove Scapes

    early July to mid-August UK average · set your town for your exact dates Dates as each sowing reaches this stage

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

  5. 05

    Harvest Bulbs

    early August to mid-September UK average · set your town for your exact dates Dates as each sowing reaches this stage

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

  6. 06

    Cure and Store

    early August to late September UK average · set your town for your exact dates Dates as each sowing reaches this stage

    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 early August to late 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.
