Growing Honeyberry Plants: A Guide to Cultivating Delicious and Hardy Fruits
Hey folks, Kevin here.
We’re standing near the berry rows at the Sanctuary in Oswego County. The honeyberries — Lonicera caerulea, also sold as haskap — are the ones that finish first. Dark blue, elongated, sweet-tart, and ready when most other fruit is still green. They come out of cold northern Asia, Europe, and parts of North America, and they handle our zone 5 winters without drama. Down to about –40 °F is no problem for the good varieties. That is why they earn a place here.
They will not fruit alone. You need at least two different, compatible varieties whose bloom times overlap so the bees can do their work. Plant three or four bushes with a mix of two or three varieties and you get more reliable set. The University of Saskatchewan releases are the ones that have proven themselves in cold climates: Aurora (large, sweet, vigorous), Tundra (firm, good for fresh or processing), Borealis (large and juicy for eating out of hand), and Indigo Gem (medium, flavorful with a tart edge). Commercial growers often put five or more bushes together for the same reason — more overlap for the pollinators.
Here in central New York, give them the sunniest spot you have. Full sun is what produces the crop. In warmer zones they can take some afternoon shade, but not here. Moisture is the other non-negotiable. These plants tolerate wetter ground better than most berries; they are not the well-drained-only type. What they cannot handle is a hot, dry, exposed site with no water. Consistent moisture the first two seasons is the difference between a living bush and a dead stick. Soil pH from about 5.0 to 7.0 works; around 6.0–6.5 is ideal. Unlike blueberries, they do not demand acid soil.
Work compost or well-rotted manure into the planting area. A soil test before you dig tells you if anything else is needed. Plant bare-root or container stock in early spring or fall. Space 4 to 6 feet apart in the row, rows 8 to 10 feet apart for a home planting. If you want a denser hedge the commercial way, 3 to 4 feet in the row still works. Set the plant at the same depth it grew in the nursery pot and water it in hard.
Mulch with wood chips or leaf litter right away. The roots are shallow — most of them sit in the top few inches — so the mulch holds moisture and keeps weeds from competing. Water deeply the first year and while fruit is sizing, roughly 1 to 2 inches a week if rain is short. A balanced fertilizer or composted manure in early spring is enough; too much nitrogen and you get leaves at the expense of berries. Prune in late winter or early spring while the bush is still dormant. Take out dead, damaged, or crossing wood. Once the plant is mature, thin a little each year so light and air reach the inside. Do not cut the tips of the productive one-year wood — that is where most of the fruit sits.
Do not expect much the first year or two. A handful of berries is normal while the roots settle. By year three most bushes give a real harvest. Full production usually arrives around year five. After that the plants keep going for decades with modest care.
Berries are ready when they are fully dark blue to purple and slightly soft. They ripen unevenly, so walk the row every few days and take only what is ripe. Fresh, frozen, jam, jelly, or baking — all work. The birds, especially cedar waxwings, discover them early and will clean a bush if you let them. Netting after the fruit sets color, or planting the row so the bushes sit a little out from the field edge, is the practical fix most cold-climate growers settle on. Aphids, spider mites, and occasional powdery mildew show up, but good air flow and basic sanitation keep them minor.
Honeyberries fit the larger design here because they give fruit before almost anything else, handle our soils without special acidifying, and stay manageable in size. They sit well with the currants, gooseberries, and thornless blackberries in the nursery rows — early season production that does not demand heroic weekly attention once the mulch and water are in place.
Next step for this season: if you are planting this fall or next spring, order two or three compatible University of Saskatchewan varieties now, mark a full-sun, moisture-retentive spot, and get the wood-chip mulch ready. If the bushes are already in the ground, check the mulch depth and plan the late-winter prune while the leaves are still off.
