Garlic Companion Plants

Garlic is a cool-season allium that needs an open, sunny bed and free-draining soil, especially through a wet UK winter. It is traditionally paired with carrots and strawberries, but evidence that it prevents pests is limited. Good spacing, clean ground and crop rotation are more dependable than companion planting for healthy bulbs.

Good companions for Garlic

PlantWhy it helps
CarrotsGarlic and carrots are a traditional pairing, with their differing foliage and root zones making a mixed row manageable.
StrawberriesMany gardeners tuck garlic around strawberry beds as a traditional allium companion, while preserving airflow and picking access.
BeetrootBeetroot can use space between wider garlic rows early in the season, provided neither crop is crowded.
LettuceLettuce grows quickly in open spaces beside upright garlic and can be harvested before bulbs need their full room.
Pot marigoldsCalendula provides flowers for insects at the edge of an allium bed without competing heavily for root space.
ChamomileIts compact flowering habit can add diversity nearby, though any direct benefit to garlic remains unproven.

Keep Garlic away from

PlantWhy to separate them
PeasGarlic and peas have different seasonal needs, and garlic's dry, open bed is not ideal for thirsty climbing peas.
Broad beansBroad beans become tall and can shade garlic, while their spacing and staking complicate access for weeding.
AsparagusAsparagus is a long-lived perennial bed that should not be disturbed by annual garlic planting and lifting.

Tips

Plant firm, healthy cloves from October to February, 15 cm apart and 3 cm deep, in a sunny, well-drained bed. Avoid freshly manured soil. Weed carefully and water only in prolonged spring drought. Remove flower stems if they form. Lift once lower leaves yellow, then dry bulbs thoroughly under cover before storage.
