Haskaps (AKA honeyberries) are hardy plants with delicious fruit – all Alaskan’s should be growing these plants in their garden!
Most haskap varieties are considered self-incompatible, meaning more than one plant is necessary to get substantial fruit set. But it is not just a simple math equation. Certain varieties are too similar genetically and will not be able to pollinate one another. And certain varieties bloom early or late, so one must consider bloom time of specific varieties.
So how many do you need? According to the University of Saskatchewan, leaders in haskap breeding for commercial and garden applications, one pollinating plant is needed for every five plants. Other sources claim planting a pollinator plant for every 2-4 plants is adequate, while others advocate planting 2 or more varieties in the same plot. As you can see, there is some disagreement in this area, but the common thread is that more than one variety is necessary to get productive fruit set! This is a true case of more is better, and isn’t it nice to be able to justify those extra berry shrubs in your cart? And of course, insects are necessary in this process to get pollen between plants.
