Blackberries in Alaska: What’s Real, What’s Rumor, and What’s Actually Possible
For ten years I’ve tried to grow true blackberries in Interior Alaska, and for ten years it has been disappointment. I’ve tried multiple varieties, different planting spots, winter protection, deep mulch, everything I could think of. Every spring I would check the row and find the same thing: dead canes. After a decade of failures, I told myself last summer I planted what would be my final attempt.
I planted a native Vermont wild blackberry variety, more out of stubbornness than hope. Most research says blackberries cannot survive here. Most gardeners say the same. And part of the confusion comes from the fact that some locals call crowberries “blackberries.” Crowberries are a native tundra berry that grow low to the ground and are completely different from the tall cane forming Rubus blackberries you see in the Lower 48. Those are the ones everyone says will not overwinter in Interior Alaska.
This spring the snow finally melted off the row and I went out expecting another round of dead wood. Instead, the canes I planted last year have swollen leaf nodes. That means the cane wood itself made it through winter, something that is almost unheard of here. No crowns pushing yet, but the canes are waking up on their own.
After ten years of trying, this is the first time I have seen real signs of life on a true blackberry cane in this climate. Success stories like this are rare, but they do happen. Sometimes it is the right microclimate, deep snow cover, or a hardy genotype that was not expected to make it.
With a low tunnel for spring heat and a mulch layer to stabilize the soil, there is a real chance these canes might actually build enough energy to grow and maybe even fruit. Nothing is guaranteed, but this is the closest I have ever come to proving that true blackberries might have a place in Interior Alaska when everything lines up just right.
Box stores always seem to have blackberry plants for sale each spring, and many new Alaska gardeners fall into the failure trap thinking they will grow here without protection. If anyone else has ever tried growing true blackberries in zones 2 or 3, I would love to hear what variety you used and whether you had any success. Sharing what works and what doesn’t helps all of us learn what is truly possible in Alaska’s short growing season.
