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 Prepare Soil
Ensure the soil is well-draining and fertile. Dig in compost or well-rotted manure to improve structure, ideally 11th February - 26th February. Remove any weeds and break up clods.
2 Plant Cloves
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 26th February - 14th March.
3 Weed and Water
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 13th March - 4th July after planting.
4 Remove Scapes
If growing hardneck varieties, snap off the curly flower scapes in late spring to direct energy into bulb growth. Do this 4th June - 4th July when scapes appear.
5 Harvest Bulbs
Lift bulbs when the foliage starts to yellow and fall over, typically 4th July - 3rd August. Use a fork to loosen the soil and avoid damaging the bulbs.
6 Cure and Store
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 19th July - 26th July after harvest.

Why Companion Planting Matters
Companion planting can help deter pests, improve pollination, enhance growth, and maximize garden space. Some plants release chemicals that repel pests or attract beneficial insects, while others can improve soil quality or provide shade for sensitive plants.
