California is responsible for about 90% of US production of garlic. Although there has been relatively little research on the impacts of climate change on garlic they are likely at low risk to heat waves because they are planted during the cool season and planting date can be changed to avoid the heat of summer. They are more likely at risk from water shortages since they have shallow roots and have a high demand for water.
