Another Overwintering Option
Another pick for overwintering artichokes is to cut back the plants to primer coat level and delve them out of the garden upon fall ’s arrival . lightly stir the soil off their ascendant and store the unsheathed - ascendant industrial plant in a boxwood of peat moss in a cold , but not freezing , garage , cellar or refrigerator . When saltation arrives , plant the overwintered bare - root artichokes back out into the garden .
Growing In Containers
In accession to growing artichokes in the garden or theater , they can be grown incontainers .
