Cool Season Vegetables include ones that grow best when the air and soil temperatures range between 40 and 70°F. Many of these vegetables will bolt or stop growing with the heat of summer. Just like the cold season vegetables, you can extend the growing season with the following vegetables by using cold frames and/or hoop tunnels with garden fabric:
Beets, Cabbage, Celeriac, Celery, Fava Beans, Fennel, Kohlrabi, Lettuce, Peas, Onions, Potatoes, Radishes, Rutabagas, Scallions, Yellow Shallots, Turnips
There are several perennials that are in the cool season vegetables:Â Â Artichokes, Asparagus, Endive, Radicchio, Rhubarb
These Cool Season Vegetables tend to bolt in heat:Â Broccoli, Cauliflower, Romanesco
Just because the above vegetables are cool season ones doesn’t mean that they are all harvested in the spring or early summer. Some like artichokes, potatoes, onions and shallots are ready to be harvested in the summer.
I have one more season category to get through – warm season vegetables.
Don’t forget when extending your gardening seasons to consider Day Length and Spring and Fall Frost Dates.
You can find this information in the future under Vegetables and then Vegetables Seasons in the dropdown menu.
