Highbush blueberry, half-high hybrids blueberry Amerikanskt blåbär (highbush blueberry, Vaccinium corymbosum) and half-high hybrids (crosses with the lowbush V. angustifolium) are long-lived fruiting shrubs. Highbush types typically reach 1.5–2.0 m, while half-high cultivars stay 0.8–1.2 m and are hardier for colder sites. They require acidic soil (pH 4.0–5.5), even moisture, and mulching. Yields improve with at least two distinct cultivars that flower at the same time. Expect first meaningful crops from year 3–4 after planting, with peak yields around years 6–10. Protect from birds at ripening. Growing conditions LightFull sun to light partial shade; full sun gives highest yields and sweetest berries. Soil typeAcidic, well-drained, humus-rich, peat-free ericaceous substrate with high organic matter. Sandy or sandy-loam with ample pine bark/wood fiber works well. Avoid calcareous soils. Water requirementConsistently moist but not waterlogged. Very sensitive to drought and salts; use rainwater if tap water is hard. Nutrient requirementLow to moderate. Use slow-release, chlorine-free, ammonium-based fertilizers for acid-loving plants. Avoid nitrate forms and heavy manuring. Back to plant list
