Haskap Across the USA

Haskap Across the USA (based in part on this blog) was presented on July 20 at the 2012 U of S Haskap Day in Saskatoon, SK. Based on feedback from across the USA, scorching heat is hard (and sometimes deadly) on Borealis and Tundra haskap, but this is not reflected in the USDA plant zones. One grower is in zone 10b due to warm winter temps, but did not have the scorching summer heat that say OK, zone 7b, had last year.

It is possible to get berries without a non-related variety nearby for pollination, but the fruit will not be as plentiful or as large. Josh in KS (zone 5b) reported "The bad news is the Berry Blue never leafed out. The good is that I have 10 small berries on my Borealis."(Both bushes from year-old stock, planted end of March 2012)

Dean from zone 10b in CA reports, "The average summertime high temp where we are in the San Fernando Valley in Los Angeles is in the high 80’s, low 90’s, and dry, and in the winter daytime temps can be in the 50’s and 60’s.

The Berry Blue is doing very well since planting in April 2011. It's gotten much larger and is sprouting new growth. I'm guessing that the plant is about 18-24" tall now. It has not sprouted fruit, but I didn't necessarily expect that it would as I've only had both plants about 1-1/2 year. The Borealis is doing OK, but has barely grown at all and there's no new growth that I can see, possibly due to transplanting from my garden to the raised bed.

Both plants have developed an odd problem. All of the leaves other than the new growth on the Berry Blue is covered in what look like water spots but are the only leaves in the yard to display such markings, and I water under the foliage."

Zone 7 - Georgia - Tundra Haskap Berries

I bought 2 Borealis and 2 Tundra haskap/honeyberryplants in the spring of 2011. I planted them at my cabin in the north Georgia mountains. We had a long and *very* dry summer (1 inch of rain over three months), and I was surprised actually to have only lost one of my four honeyberries (one of the Borealis). The other plants are actually thriving in part sun it seems. Considering how hot and dry the summer was here, that's pretty good for a plant that is supposed to live in the frigid north!

Anyway, this email was just to send you pictures of my first harvest (from the Tundra plants). Not a lot yet, and I'm pretty sure these weren't even pollinated (my pollinator plants are still too small). But let me tell you they sure were delicious :)  Kevin, Georgia

Zone 5b - Maine - Borealis and Tundra Haskap Blossoms

They did well their first year with most more than doubling in size, and by the beginning of winter I was super psyched for this spring and the possible berries it would bring. Well they didn't disappoint as the plants have not just already doubled in size again (in just 3-4 weeks) but they are loaded with little berries with plenty more flowers out and forming.

Zone 5a, Illinois - Borealis Haskap Survivor, planting tips

"The leaves on the plants developed brown spots and 7 out of 8 have died. This plant survived after spraying it with an anti fungal spray. I could have done a better job gradually exposing the plants to full sunlight. I planted the berries in Miracle Grow potting soil assuming that they would do well in that kind of soil." Doug, IL (late June planting)

(Editor's notes)
Ideal planting time: late fall or early spring, with dormant plants that can go directly into your pots or ground soil, but we have had very good success with later plantings as well (<2% fatality rate for late June planting). When actively growing plants are shipped, they need adequate hardening off, gradually increasing their exposure to direct sunshine over a 5 day period if the sun is strong.

Brown spots on leaves: The leaves may develop some brown spots during shipping. Our state inspector recommended treatment with a copper fungicide available at local hardware stores, but said it wasn't anything to be overly concerned about. Our experience has shown that the overwhelming majority of plants will survive and produce new growth. Also, in windy areas, the undersides of the leaves may be exposed to the sun scorch (brown streaks) but the leaf does not wither and the plant still survives.

Fertlization: The plants have been given good nutrients in the nursery and do not require additional fertilization the first year, though testing needs to be done to determine what fertilization schedule would be optimal. Aged manure is the tried and trusted fertilizer of choice but we are also looking into other ecologically-based options such as the water soluable 2 step program offered by EarthSoils.  Dry fertilizator spread on top of the soil has burned the bark and killed other growers' plants. Applying water soluable fertilizer in excessive amounts will damage the plants as well. Do not apply fertilizer past mid summer so that the plants do not continue to put out new growth, as they need to prepare their roots for dormancy. 

Thank you, Doug, for sharing your experience and fotos. We not only publish success stories but seek to learn from all experiences, so congratulations on being our HoneyberryUSA 2011 Foto Contest Winner! We trust you'll have better success with your replacement plants in the fall!
