Site: full sun for best yield; well-drained soil rich in organic matter, tolerates acidic and alkaline; mulch with well-composted organic matter to retain moisture. Planting: spring once frost risk has passed, allowing a summer to establish; plant in pairs/groups for pollination. Pollination: flowers late winter to very early spring when there is little pollinating insect activity -- hand-pollinate with a small, soft paintbrush. Pruning: young plants need only dead material removed for the first three years; established plants pruned early-mid summer after harvest -- remove weak/straggly/damaged growth, thin overcrowded shoots at the base, trim young shoot tips to encourage flowering laterals. Harvest: late spring to early summer, about two years to first crop; mature plant yields about 6kg; berries ripe when blue with a whitish bloom and purple-red flesh (green flesh means still sour). Pests/diseases: very hardy, no significant issues reported. Propagation: by seed (remove pulp, sow in warm moist conditions, no cold stratification needed), semi-ripe cuttings from non-fruiting stems in summer, or hardwood cuttings late autumn to winter. Height/spread 1.2m (4ft); hardy to -40C.

Site: full sun to thrive (part sun gives less fruit); tolerant of most soils, best in well-drained loam or sandy loam, tolerates clay if well-drained. Hardiness: zones 1-4, U of S cultivars bred for cold hardiness, no winter protection needed. Spacing: at least 1m (3ft) apart, planted 2.5-5cm (1-2in) deeper than nursery depth, hole big enough for the whole root mass; keep grass/weeds clear within about 1m (3ft) of newly planted stems. Pollination: self-incompatible, needs another haskap of a different, simultaneously-blooming variety; pollinated by bees and other insects; at least two plants needed for a home garden. Pruning: fall or winter (form easier to see); doesn't typically need much; can rejuvenate by cutting back to ~15cm (6in) above soil and letting it regrow. Harvest: late June to early July; berries look ripe 5-10 days before they actually are; fully grown shrubs yield 3-4.5kg (6-10lb) a year; hand-picking works best, or shake into a container. Storage: 3-5 days refrigerated short-term; freeze, ferment, dehydrate or can for the long term. Pests/diseases: birds are the most common problem, netting with holes no larger than 1.25cm (0.5in) recommended; occasional sunscorch, cosmetic only. Propagation: commercial cultivars can't be grown from seed, propagated asexually via tissue culture; named cultivars are patented, propagated only by licensed growers. Named cultivars: Tundra, Borealis, Indigo Treat, Indigo Gem, Indigo Yum, Aurora, Honeybee, Blue Bell, Berry Blue, Cinderella -- berries range 0.7-2.17g each.

Plan next season before the problems start
Short-season growing is arithmetic before it is technique: days to maturity against frost-free days decides what will finish at all. The Canada Garden Planner does that subtraction for your region before you sow.
