Blueberry in Zone 6a & 6b
Vaccinium corymbosum
When to plant blueberry in zone 6b
Zones 6a and 6b share the same average frost dates in our data, so this page covers both.
Method: Buy as a start: Buy as a nursery start and transplant outside. Blueberry is slow or unreliable from seed, so most gardeners skip seed-starting it entirely.
| Start indoors | Not started from seed; buy as a nursery start |
|---|---|
| Direct sow / transplant outside | Mar 28–Apr 4 |
| Estimated harvest | Mar 27 '30–Apr 3 '30 (First real harvest in year 3) |
Spacing: about 20 square feet per plant (square-foot-gardening spacing). Mature height: 3-6 ft.
Blueberries are the fruit people most want to grow and most often fail with, and the reason is almost never the climate. It's the soil.
How blueberry fits zone 6's season
Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Blueberry takes about 2 growing seasons to reach first worthwhile harvest, so what matters here is how many of these seasons it gets, not whether one is long enough.
Blueberry is hardy in zones 3-8, so in zone 6b it stays in the ground through winter and comes back rather than being replanted. Allow about 4 ft of spread at maturity.
