Growing Winter Squash in Alaska

Some extraordinary gardeners like Virgil Severns and Terry Reichardt have been growing winter squash in Alaska for years, but for us ordinary gardeners, it’s becoming a much more reliable and feasible crop. 

If you’re gardening for food security, squash is a great option because you can store it without having to freeze or can it (and incidentally, you should NOT can pumpkins or squash at home according to the National Center for Home Food Preservation, but you can can cubed winter squash). Storing as is saves time during the mad dash of fall when we are trying to cook and eat all of the fresh produce from the garden or preserve what we can’t eat; as well as pick berries, fish and hunt. Not only does winter squash actually provide some calories as opposed to greens, it is paleo friendly, gluten free, delicious and nutritious. If you don’t have the space to grow squash, you can find locally available winter squash here.

Indisputably, the most knowledgeable and experienced winter squash and pumpkin grower in Fairbanks is Virgil Severns. He has grown the crop for over 30 years with his wife Anne and recently published a pamphlet on the topic. I wondered what attracted him to the crop originally and he said, “The thing that got me started really, years ago, the experiment station and the plant materials center offered a bunch of seeds and so I got some of those seeds and I planted them and they did well so it got me started growing squash.”

The pamphlet explains which varieties will grow best in Interior Alaska and cautions that some types (acorn, butternut, delicata, and sweet dumpling) are sensitive to our long days and as a result, do not produce female flowers in time for the fruits to mature. Continue reading
