This is a good article summarizing project to compare effects of location and cultivar of three northern highbush and six half-high blueberry cultivars on survivability, fall dieback, winter injury, fruit yield and weight at two locations on the Kenai Peninsula. Results suggested ‘Northblue’ as the most promising cultivar followed by ‘Northcountry’, ‘Northsky’, and ‘Polaris’. Unfortunately this project was discontinued due to shrinking budgets after the first year of fruit production. CZ Anchorage

The links below compare pruning techniques between highbush and lowbush blueberries. Although I assume most of us are not interested in growing highbush blueberries, I still think it is an interesting comparison. The first link is a video bythe University of Maine on how to prune highbush blueberries on a blueberry farm. I like that he points out how to looks for vegetative vs. fruiting buds and which branches to prune out to improve fruit quantity and quality. In the video a loppers is used to prune the bushes. The second link is a publication, also by the University of Maine, about pruning lowbush blueberry fields. The techniques suggested here are thermal pruning (eg burning) and mowing, which is quite a different approach! The timing of pruning is the same for both, which is during plant dormancy- late fall after a hard frost, during winter or early spring before bud break. KMD Fairbanks
From the Bog to the Box
I have two acres of land just north of Fairbanks that I am currently in the process of building a home and planning a landscape on. When I think about what I want my yard to be like I think about what I want to do in my yard. I’d like to walk through the trees, enjoy the song birds and of course have an aesthetically appealing landscape. But to me the stimulation from the landscape needs to be more than simply looking pretty, I want there to be good functionality in my yard. I want pretty flowers, but I’d like them to be simple, natural and perennial. I’d also like to be able to harvest edibles from my landscape and not just from my garden and green house. These reasons along with others are why I want to manage the wild berry stands I currently have growing as well as adding a few transplants. The berry I am most interested in transplanting and managing is the Bog Blueberry.
Unconventionally I am most interested in the idea of transplanting wild bog blueberries into low but still raised garden beds that would line my driveway and possibly other pathways around the property. Although we do not currently have the house finished, I think that next summer would be the best time to begin transplanting blueberries into the driveway in order to possibly have berry production by the time we are finished with the house and I will have more time to focus on other areas of the landscape. That way, I will have a few years of experience with these before deciding what to do with the rest of the space.
I think that raised garden beds or boxes would be good for experimenting with berries because I will have complete control over the soil composition and watering/irrigating processes and this will give me more detailed information on what is and isn’t working. At the same time though, I think I will also transplant some bog blueberries into the cleared powerline on the opposite side of my property just to be able to compare notes on the original source, and both transplanted sources, completely controlled vs. simply transplanted and observed. Some key things for me to keep in mind about transplanting and box gardening are soil preferences (nutrients, water absorption and irrigation, pH levels), available sunlight, preferred pollinators, and nearby plant species.
Blueberry soil preferences: Blueberries tend to require an acidic soil composition with pH levels of 4.5-5.5. Some berries secrete root acids to help bring iron and other nutrients into a solution they can absorb but blueberries do not secrete these acids and thus they rely on organisms that thrive in acidic soils to help convert nutrients for them. Bog blueberries can thrive in a variety of moisture conditions from highly aerated to poorly drained soils, and often grow in mat layers with roots in shallow but wide areas. Loamy or peaty soil compositions are good for blueberries and adequate watering is a must. Do not let the roots dry out, while also not drowning them. Because I want to build raised beds or boxes for my blueberries I will have complete control over what I make my soils with and I plan to try to use natural loamy soils and peat from local bogs.
Sunlight: Blueberries do well in sunlight areas, often much better than in shade. Because most of my property is undeveloped I think the edges of the driveways will produce sufficient amounts of sunlight without too much heat.
Pollinators: I have a variety of pollinators that live in the nearby woods and am happy to say that there seem to be an abundance of bees in my neighborhood. Another reason my driveways will be a good place to start is because both neighbors on either side of me have bee boxes near us. Honey bees, bumble bees, hornets and a variety of other pollinators are attracted to the wild currants, raspberries and rose hips already growing here so I do not think I will have a lacking of good pollinators. Possibly Ill even be able to trade blueberry jams for honey…
Native plant species: Although I have a diverse collection of other berries, trees, bushes and some wild flowers, I do not think these native species will be of much concern for the blueberries because of the raised beds. I will have to keep up on weeding and pruning, but I do not have any super invasive species other than the raspberries that are spreading themselves about each year (I don’t mind that at all).
I do have a lot of work ahead of me in building the ideal beds that will contain but not limit blueberry growth as well as the effort in creating good balanced soil, and transplanting berries adequately, but I look forward to the experimenting I will be doing for the rest of the foreseeable future.

It is simple to follow and full of good information. Not all information is specifically for the bog blueberry, but still has good tips and ideas to get started.

Here is a fruit blog dedicated to strawberries and caneberries (ie raspberries and blackberries): http://ucanr.edu/blogs/strawberries_caneberries/index.cfm?tagname=strawberries. It is administered by University of California Agriculture and Natural Resources. Not everything is applicable to AK, but I think its an fun site to check out and see what people are dealing with in regards to berry growing in other parts of the country.

Managing a backyard blueberry patch Although sadly, I’ve moved, for five years I enjoyed a glorious backyard blueberry patch. It was lightly cultivated but I think that cultivation was well worth it in terms of production. I think the low hanging fruit in terms of easy cultivation for my patch was, weed whacking the alders and willows and large trees and pruning the bushes with hedge shears (every other year). Other things that I think would contribute to success and would be easy to do are getting bees. I also had chickens for awhile and they went crazy over the blueberries. They contributed a little of fertilizer, but I usually tried to coral them into the garden so that they wouldn’t eat too many blueberries. I’m curious how some of these more intensive cultivation methods used in Maine for example, would work Yarbororough, 2013). Specifically, how many pounds of bog blueberries could be produced on one acre? But then you’d sacrifice the organic nature of our wild blueberry stands. And also, with so many free blueberries on public lands, would it be worth it? I think it is for the easy methods but not sure about irrigation, fertilization, ect. I find it interesting that they call these wild blueberries in Maine with such intensive cultivation? Yarborough, D. 2013. Production-Improving your wild blueberry yields.

I visited a gentleman in Palmer last week who has been busy cultivating our wild high bush cranberry, Viburnum edule. The DOT widened the road in front of his house and he rescued quite a few high bush cranberry plants before they were inundated with gravel. He held them in cold frames of potting mix for one winter and planted them out beginning in June 2016. Even in the raised beds, they had begun to spread, and they were well established by September. No doubt about it, south central Alaska is a great place to grow high bush cranberry, and they transplant very well. Can’t wait for the updates on productivity and to try the wine he wants to make!!!
Transplanted bog blueberries, Vaccinium uliginosum, from the wild can be planted in a garden with soils amended with peat moss. Productivity can be incredible once the plants become established. They also root from buried stems, and these can be cut from the mother plant and transplanted into a garden. Stem cuttings and seeds also work.
A good read on alleycropping put out by the University of Missouri Center for Agroforestry. It includes definition, design, operation and maintenence, and success stories! Alleycropping

Soil pH wrong for blueberries? Blueberries like acidic soils and it’s unlikely that your garden naturally has the perfect condition. The Alaskan Berries website has a soil recipe geared towards Alaskan soils. It also has helpful hints for growing other berries. Soils and Blueberries
I really want to try this, we have old piles of trees that are burn piles now. Just think how interesting it would be to use those logs and brush for hugelkultur!
