Anyone growing Kinnikinnick? I started this little patch from 3 cuttings a few years ago, but haven’t had a single flower much less fruit. It’s growing like crazy, though. I’ve read they do best with low fertility, this area is under my blueberries so it gets a lot of nitrogen (ammonium sulfate), maybe that’s the problem?
Also observe my new fruit defender. All 6.5 lbs of her, haha.
Kinnikinnick grows wild out here. I had never heard of anyone cultivating it, but it seems happy in our environment: generally dry, alkaline soils (pH in the mid 7’s), and not much natural fertility in the soil.
The only thing which stands out as a major diff, is blueberries want an almost opposite set of conditions to our wilds here (they want acid soil and lots of moisture). Perhaps the KK would be happier if you moved it to a drier and less acidic spot rather than where blueberries are happy?
It’s odd, it is growing well vegetatively (1’/yr). I still no bloom.
I mostly planted it for ornamental use, but if it fruits I’ll try it!
The only place I see it growing around here is in sandy soils, under jack pine. Yours looks vigorous but it is still very young… give it another year or two and I think it will bloom and fruit for you. The berries from kinnickinick that I’ve sampled here are very dry, mealy and tasteless, so don’t set your hopes too high!
