Bump Up Your Strawberry Production

 

There are never enough strawberries in our patch — I think my kids and my neighbor’s kids would agree!

I am not the only one who is figuring out how to grow strawberries successfully in Alaska. One of the top posts on my blog, It Grows in Alaska, is Untangling the Mysteries of Growing Strawberries in Alaska. To figure what I can do to bump up my strawberry production, I interviewed Andy Harper, a local strawberry farmer (Highlands of Alaska Farms) as well as University of Minnesota researchers who have studied annual strawberry production using a low tunnel system.

Andy has a half acre of strawberries in production this year. Some of those plants are research plants. He said he started the farm because, “I love berries, I lived in the UK and Scotland, they love black currants, I love those. I met Papa [Meunier] and he had everything. All different types of berries. I just loved berries. So I decided I wanted to do berry farming. Strawberries are the only ones I can make money on the first year.”

Evelyn Sarten and her late husband Ed (Dwight) have gardened in Ruby, Alaska, for a quarter of a century. Evelyn, who was raised on the land on a Native American reservation in Taos, New Mexico, estimates she grows about 30% of her food. 

She was taught to live with the land and she’s always grown her own food. Their garden in Ruby is characterized by innovation and making do with what is available. For instance, their chicken coop fence was constructed from an old couch frame, old bed frames, and leftover fencing from the school. Now her one remaining chicken lives in her Arctic entryway.

In addition to growing her own large garden, she also works for the Native Village of Ruby as the natural resources and agriculture program director, helping others in Ruby garden as well. With Evelyn, I and the Tribes Extension Program (www.uaf.edu/ces/tribes) sent out vegetable and flower seeds and organized gardening and plant foraging workshops at the school. We also purchased and built a raised bed garden for the school.

Gardening in the Wind

 

I grew up in Fairbanks and according to my memory, it was never windy. Without wind, 40 below zero is not that cold. Without wind, you can water your garden and it stays moist for the day. Without wind, plastic row covers do not blow away. You get the idea. I am not a huge fan of the wind. 

This spring, in addition to the wind, we had very dry (drought) conditions. I direct seed a large portion of my garden and the seeds need to be kept wet until they emerge. Keeping the seeds moist was really hard to do this spring because of the combination of hot, dry, windy weather. To keep the seeds moist, I used drip irrigation, covered the seedlings with Remay (frost cloth), and watered the seeds sometimes three times a day with a sprayer hose. Later in the summer, it is so much easier to keep a garden watered because the plants provide shade and they have roots.

Not only did the breeze seem to be a more constant companion this spring, there were also a couple of uncommonly intense windstorms in July and August. In Golden Valley Electric Association’s (GVEA) Ruralite magazine (September 2022), Josh Davis, the director of operations said, “The July wind storm was the worst storm we’ve had in my 18 years here.” He noted that the August windstorm was also pretty bad.

Building Your First Greenhouse

 

There are plenty of reasons to build a greenhouse in Alaska if you don’t have one. Having a greenhouse could extend your growing season, give you a place to grow starts (if you have a way to heat it), or allow you to grow warm-season crops like tomatoes, peppers, and cucumbers with ease, as well as to eat other crops earlier than you otherwise would. 

But growing in a greenhouse requires more management than an outdoor garden. When it rains, it will not water your greenhouse plants. When it’s hot, you’ll need to make sure it doesn’t get too hot. When it’s humid, you’ll need to ensure adequate ventilation. Pests can multiply quickly in a greenhouse and can be hard to eradicate once there. But those are all manageable problems.

Raised Beds Make it Possible to Garden Just About Anywhere

 

Gardening in raised beds offers a lot of benefits, and a few drawbacks. Raised beds are a great option for gardening on top of a porch, concrete, or on poor, rocky soil. They’re ideal for corralling good soil while keeping it from getting compacted. They make it easy to employ no-till gardening and to eliminate weeds in the aisles, especially if your walkways are made of concrete or something else that completely keeps weeds from growing.

Gardening in the Aleutian Pribilof Island Region of Alaska

 

For this article, I interviewed two people who have gardened or farmed in the Aleutian Islands. Lily Stamm manages a geodesic dome greenhouse in Nikolski, Alaska, located on Umnak Island. Two domes were erected in 2003, one of which has since blown away. I also interviewed Michael Livingston, who homesteaded with his family in Cold Bay in the 1960s. You can watch the video of these interviews here. If you are a gardener or grower in the Aleutian and Pribilof Island region and are interested in sharing what you know, or photos and videos of your garden, please contact Heidi Rader at hbrader@alaska.edu.

Stretch Your Growing Season Into the Fall With Season Extension Techniques and Cold Hardy Vegetables

 

Although the growing season in Alaska is short, particularly in some areas, it’s getting longer. Still, from year to year, there are noticeable differences in the length of the growing season. Season extension techniques help deal with some of this year to year variability and make the most of your season. You can protect your plants from frost and cold using a range of season extension techniques: frost cloth, low tunnels, cold frames or hoop houses.

Frost cloth can be used to create a low tunnel to help insulate plants from cool temperatures.

Frost cloth, or row cover, comes in a variety of weights – the heaviest can protect plants down to 24 degrees.

Low tunnels are constructed from metal hoops and can be covered with frost cloth or plastic.

Cold frames can be insulated and/or heated (hot bed). You can even make a rudimentary cold frame with straw bales. If you’re willing to add heat to a cold frame (known as a hot bed) or high tunnel, you can extend the growing season even further into the winter.

Old windows can be used to create a structure called a cold frame. Here, a cold frame is erected over a raised garden bed.

Hoop houses and high tunnels are another option. They provide a little less protection than cold frames because they are usually constructed from simple structures and use a plastic covering.

If you have extra room in your greenhouse, you can plant cold-hardy vegetables in mid- to late summer, but it might be hard to take precious space from your tomatoes and cucumbers when they are at their peak and give it to the lowly corn salad (mache). Continue reading

UPDATED: Greenhouses Remain Open in Fairbanks and Continue to Serve Rural Alaska

 

With the burgeoning interest in gardening this year, many will probably be relieved to hear that, so far, greenhouses in Fairbanks plan to remain open. They are planning on filling a critical role in helping people improve their own food security, and just as important, their mental health this summer. I interviewed Stephanie Bluekins, owner of the Plant Kingdom and Glen Risse, owner of Risse Greenhouse, about how they plan to meet the demand for all things gardening both in Fairbanks and in rural Alaska.

At both greenhouses, you can make an order online or by phone and schedule a pick-up time. When you arrive at the greenhouse, call and let them know you’re there and they’ll bring your plants and other products out to you. In lieu of their normal in-person workshops, The Plant Kingdom is planning virtual workshops, which may be accompanied by an appropriate kit. Risse greenhouse isn’t quite sure what they will do instead of their large in-person events.

UPDATED: As of 4/20/2020, Risse Greenhouse is open to the public. The Plant Kingdom is also planning to open to the public to some extent. Contact the greenhouses for the most up to date information on hours and special procedures or shopping protocols related to COVID-19.

I also asked them about their continued dedication to serving the needs of villages in rural Alaska. Stephanie is Alaska Native with family throughout rural Alaska and is committed to working with rural Alaska. She offers Bush orders and currently provides a flat rate of $35 for a packing/pulling price in addition to the cost of purchased items and shipping charges. For Bush orders, Risse Greenhouse charges a percentage of the cost of the items purchased as well as shipping. Continue reading

Homer is Passionate About Local Food–and Those Who Produce it

 

In spring of 2018 I had the happy excuse to visit five farms in Homer–to film high tunnels and season extension techniques for a YouTube series called, In the Alaska Garden with Heidi Rader. While I was there, I kind of fell in love with those farmers. Their passion, tenacity, and creativity was infectious and rekindled my own dream of being a farmer I discovered they’re innovating in lots more ways than high tunnels. I say farmers but they all also identify strongly with the term “market gardener”–a term that describes farmers who grow food predominately for direct markets using mostly low-tech, hand tools on small acreage. They are voracious readers, watchers of YouTube videos, and sharers of ideas. Some of their favorite authors and vloggers include Eliot Coleman (The Four Season Farm), Ben Hartman (The Lean Farm), Curtis Stone (The Urban Farmer), and Jean-Martin Fortier (The Market Gardener).

My first stop was Homer Hilltop Farm where Carey Restino has carved out a farm that winds through forest and devil’s club on Diamond Ridge. Carey exuded energy as she showed me her high tunnels and hoop houses that have helped her dramatically extend her season in a microclimate that is cooler than Homer proper due to its higher elevation. She had an impressive lineup of the latest, low-tech tools designed for market gardeners including a six-row seeder, a Quick Cut Greens Harvester, and a soil tilther to name a few. Continue reading

Corn—The Holy Grail of Alaska Gardeners

 

Growing corn in Alaska is a pain in the neck. If you’re lucky, the summer is hot and you get a few ears. If you’re not lucky, and the summer is cold and rainy, you get zilch. Either way, a lot of effort and garden space goes into your attempts with mixed results.

Still, Alaska gardeners’ eyes light up when you talk about growing corn in a way you don’t see when you mention, say, kale, which is so much more reliable, nutritious and higher-yielding. Maybe part of the allure of growing corn is the challenge. Or maybe that it’s about 10 times sweeter than kale. If you get a twinkle in your eye when you hear corn-growing talk, here are some things you should know.

First, you will want to choose a variety that matures in around 70 days or less. You’ll also want to consider the genetics of the corn variety you’re selecting and not just for curiosity’s sake. It’s important for predicting cold hardiness, sweetness, seedling vigor (in cold soils), the shelf life or rate that sugar turns to starch and isolation requirements. I’m not going to lie, it’s a little bit confusing, but Delaware Cooperative Extension, does a great job of delineating the corn by their genetic traits. Johhny’s Seeds also provides a nice comparison of sweet corn types. Continue reading
