Haskap in the garden
Practical starting points for choosing compatible plants and caring for them through the seasons.
TOOLS FOR GROWERS
Plant habit, pollination, berry size, powdery mildew, harvest and the differences between Lanoraie trials and our observations at Saint-Gabriel.
Each number keeps its trial site and year so a research result is not turned into a promise.

Open the buying guideChoose full sun for the best fruit production. A haskap shrub can grow in partial shade, but it will generally produce less fruit. Loamy or sandy-loam soil with good drainage is a useful starting point. Clay soil may also work when water does not remain around the roots.
Haskap roots are wide and shallow. Keep roughly one metre around each plant free of grass and weeds, then use mulch to conserve moisture without piling it against the stems. Before planting, watch how water drains after rainfall and leave enough room for mature growth, maintenance and harvest.
Dig a hole large enough for the entire root ball. Set the shrub approximately 2.5 to 5 cm deeper than it stood in its container, backfill carefully and water thoroughly. Keep the soil moist but never waterlogged during the first two or three weeks.
Leave at least one metre between plants, then adjust for the mature size of the cultivars you selected. As plants become established, water at the base and toward the outside of the canopy. Rainfall, drainage, heat and soil type should determine the actual watering schedule.
Do not fertilize a young shrub at planting. The University of Saskatchewan guide suggests mature compost or well-composted manure around the plant before mulching. An annual spring application can provide slow nutrition to an established shrub.
Use granular fertilizer carefully because shallow roots take up nutrients quickly. A local soil test is more useful than fertilizing automatically. If a fertilizer is needed, follow a recommendation suited to your soil, plant age and product label rather than assuming that more will produce more fruit.
Haskaps are self-incompatible: two plants of the same variety are not enough. Plant at least two genetically compatible varieties whose bloom periods overlap. The flowers are complete, so there are no separate male and female shrubs; both compatible plants can produce fruit.
Bees and other insects carry pollen between flowers. Cold, wind and year-to-year changes can shorten bloom overlap. Keep the plant labels and verify an up-to-date bloom and compatibility chart before buying an additional shrub.
These four pairings come from the University of Saskatchewan chart. Use them as a starting point when choosing plants, then check bloom overlap where you live.
| Your cultivar | Partner to check |
|---|---|
| Aurora | Indigo Gem |
| Indigo Gem | Aurora |
| Boreal Beauty | Boreal Beast |
| Boreal Blizzard | Boreal Beast |
Boreal Blizzard and Boreal Beauty are a poor pairing on their own: their bloom overlap was limited in the university’s observations, while Boreal Beast pairs well with either one. Local bloom timing can change from year to year. The varieties on our site are not a purchase recommendation. Check the original compatibility chart ↗
Haskap shrubs generally need little pruning. During dormancy, remove dead, damaged or genuinely crowded branches; damaged wood can be taken out when noticed. An older shrub with declining production can often be renewed gradually after assessing its vigour.
When and how to prune haskapBirds are often the most visible problem and can remove berries quickly. Install a well-secured, small-mesh net before the berries turn blue. Support it on a structure and close the bottom so birds and small animals are less likely to become trapped.
Blue skin does not always mean that the inside is ripe. Taste several berries before harvesting. For yellow leaves, weak growth, mildew or unexplained damage, record the cultivar, date, weather and affected plant parts. Seek Québec diagnostic advice before applying a treatment at random.
Use complete horticultural references when you need exact production or diagnostic instructions.
In practice, you need at least two compatible varieties that flower at the same time to support cross-pollination.
The partner variety, bloom overlap, weather and pollinator activity can all affect fruit set.
Plan the main pruning during dormancy, after leaf fall or before spring budbreak. See the method for young, mature and older shrubs.
Outside colour is not enough. Texture, interior colour and taste change with the cultivar and season. Follow local harvest guidance.
At Camerise St-Gabriel, we grow haskap without pesticides or herbicides in Saint-Gabriel-de-Brandon, in northern Lanaudière. A seasonal visit lets you discover the fruit and ask questions about our orchard.
