When to plant Garlic in London

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.

Growing guide

What to do through the growing season

Change the guide to see different planting timelines and tips.

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

  1. 01

    Prepare Soil

    18 Feb to 5 Mar

    Ensure the soil is well-draining and fertile. Dig in compost or well-rotted manure to improve structure, ideally 18th February - 5th March. Remove any weeds and break up clods.

  2. 02

    Plant Cloves

    5 Mar to 21 Mar

    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 5th March - 21st March.

  3. 03

    Weed and Water

    12 Mar to 19 Jul 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 12th March - 19th July after planting.

  4. 04

    Remove Scapes

    3 Jun to 19 Jul 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 3rd June - 19th July when scapes appear.

  5. 05

    Harvest Bulbs

    3 Jul to 18 Aug Dates as each sowing reaches this stage

    Lift bulbs when the foliage starts to yellow and fall over, typically 3rd July - 18th August. Use a fork to loosen the soil and avoid damaging the bulbs.

  6. 06

    Cure and Store

    3 Jul to 25 Aug 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 3rd July - 25th August 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.
