Where to buy Plan its pollination partner
A University of Minnesota half-high: half highbush, half lowbush, bred to survive serious winters under snow cover and still crop on a bush you can pick without stretching. University figures put a mature Northblue at roughly 3–7 lb of fruit — remarkable for a plant under 3 feet.

Pollination
This variety is self-fertile, so one bush will fruit on its own — but a compatible second variety planted nearby reliably means more and larger berries, which is why nurseries and extension guides recommend planting in pairs or trios.

Before you plant
- Soil pH 4.5–5.5, tested before planting — the pH guide
- Full sun (6–8+ hours) and soil that never sits soggy
- Space highbush 4–5 ft apart, rabbiteye 5–6 ft, dwarfs 2–3 ft — planner
- Remove flowers in year one so the bush builds roots, not a handful of berries
