About this guild
Onions, garlic, leeks, chives, and elephant garlic release sulphur compounds that deter many pests — classic partners for carrots (carrot fly) and brassicas. Alliums and legumes are famously incompatible in the same row.
NZ note
Garlic rust is common in humid areas — rotate and avoid overcrowding.
