Haskap indoors - Svetlana Surprise

I brought in a potted Svetlana, last year's rooted cutting from a propagator in Canada, and it totally surprised me by leafing out and forming little buds all along its stem, all in just one week! Svetlana berries supposedly have a good taste and this week's experiment shows it is indeed very fast growing. Bernis, MN

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 3 - Forest Tent Caterpillars dine on haskap leaves

Every ten years or so the forest tent catepillars arrive en masse and this year there is a new item on the menu - haskap leaves!

So far there are a couple of caterpillars per plant on one end of the orchard. Most of the growth has occurred already (12-24") and the berries are starting to turn purple.

They seem to turn purple overnight, and yes, you will just have to taste one before it's ready, but the sourness will definitely encourage you to wait another 3 weeks for the rest to ripen to a more palatable taste!

Tundra haskap

Potted haskap will ripen a good week or two prior to the ones planted in the ground. These Tundra berries look like they are ready to eat, but still need a couple more weeks to turn sweet.

Borealis and Tundra blossom over the span of a week or two, so we probably want to wait a good month from the time the first berries turn dark blue until harvest. However, Chris in CT reports, "My kids ate the berries before they fully ripened. They liked their tartness."

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.

Fall Haskap Blossoms

Lonicera Caerulia L. have not ceased to surprise me. Our biggest plant, a 3-year-old potted Tundra was accidentally left out in the hot sun for a several days in late August and completely dried out. Most of the leaves shriveled up and fell off. Having seen tremendous tenacity in other blue honeysuckles that had come upon hard times, I doused it with water and kept up with the moisture for the next month. But not seeing any new growth, I thought I would have to wait until spring to determine if it survived. Can you imagine my shock to find this gorgeous cluster of blossoms at the end of one of those "dead branches"?

Then the question was whether these blossoms would turn into berries. While another blue honeysuckle plant of a different variety is recommended for maximum fruit production, it is possible to get fruit without another plant. And sure enough, this Tundra did not disappoint us. Out of the half dozen or so blossoms, we found three little green berries! Another twenty days or so and they should be ripe!  - Nov. 15 update: no berries matured :-( Guess I'll have to wait 'til spring!

I have also seen haskap survive after being stripped of all its leaves through accidental weeding. Haskap may need at least a month or more to show any sign of life, so don't give up on them too soon! Only 1.3% of this spring's shipment did not survive transplanting for unknown reasons, and once they get established they are very hardy.    -Bernis, northern MN

Zone 3 - MN - Tundra haskap berry surprise

While down on my knees hand weeding the haskap plants in our orchard I was shocked to find blue treasure! Yes, there at the end of the older wood (but still first year growth) was a Lonicera Caerulia berry! I found six of these precious gems on six bushes, or on 2% of the Tundra plants. No berries were found on any Borealis or Berry Smart Blue plants. No berries were found on the year old plants (2nd year growth) that had produced blossoms earlier in the season. So what was it that made those select 2% Tundra plants so special?

Foot tall, first year Tundra plant with berry

These bushes were propagated by tissue culture in the winter of 2011, nurtured in the greenhouse in Canada until mid June, shipped to Minnesota and planted at the end of June. Six weeks later these berries were discovered. Even though the berries look ripe on the outside, the one berry I sampled was quite tart, indicating it lacked a few weeks yet to fully ripen inside.

"Starting with day zero when the flower is fertilized, cell division occurs during days 0 – 23. High respiration occurs during this phase, i.e. plant uses lots of energy to build cells. This may be the most crucial phase for watering haskap. Cell expansion occurs during days 24 – 42, when the cells get filled with water. The berry is green and very firm until day 23. Almost overnight it turns blue on the outside, but needs about three more weeks for the inside to turn dark blue indicating it is fully ripe." (James Dawson, grad student, U of S)

What I've seen of Tundra and Borealis is that they can be expected to grow about a foot a year, up to their adult height of approximately 4 feet. I have seen their growth stunted in highly alkaline soil (>7) and heard that highly acidic soil (<5) is not ideal either. Our foot of topsoil has plenty of organic matter with ph 6.5 and heavy clay underneath. The plants have done very well so far with plentiful rainfall this year.   Bernis, northern MN
