Abstract: Wild leek (Allium tricoccum) is a forest spring ephemeral popular amongst consumers. Overharvesting caused a major decline of its natural populations in southern Quebec, Canada. Forest farming could provide a mean of sustainable exploitation of this vulnerable species. According to our experiments, planting under late bud-bursting tree species improves growth of wild leek, which delays its senescence and can acclimate to the higher light availability. A lower planting density improves individual growth and reproduction, but lowers the yield per cultivated area. Partial harvest of the bulbs in dense populations slightly improves post-harvest growth. Harvesting leaves does not affect survival, but delaying it in the season and harvesting only one leaf out of two favors regeneration. These results will allow optimizing yield in wild leek cultures.
