Last summer I grew a number of winter squash, edible gourds, and pumpkins. I am still eating the harvest as these all keep wonderfully in a 60-65 degree basement/root cellar environment.
Tho squash have their own set of growing issues such as squash beetles, vine borers, and powdery mildew, wouldn’t winter squash such as acorn, butternut, spaghetti, etc., be as good or better a choice than potatoes?
I know potatoes are good choice in northern environment, but much of US is more temperate...Thots?
Potatoes are a good choice here up north. The only thing people need to do is make sure they use a variety that has good storage properties.
Squash grows well up here, too, so a combination of those two will give you variety.
