Wild garlic prefers moist, humus-rich soil in partial to full shade, making it ideal for woodland-style planting or under deciduous trees and shrubs. Plant between 15-30cm (6-12in) apart. Once established, it can spread quite freely, so it's best to keep it contained if you don't want it to naturalise. If it becomes too vigorous, clumps can be lifted and divided in autumn or early spring.
In early spring, as growth begins, apply a balanced, slow-release fertiliser to support healthy foliage and flower development. Water during dry spells, especially in the first year after planting. Allow the leaves to die back naturally after flowering, as this helps feed the bulbs for the following year. Only tidy up once the foliage has fully withered to avoid weakening the plants.
