Raspberry in Zone 5a & 5b
Rubus idaeus
When to plant raspberry in zone 5b
Zones 5a and 5b 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. Raspberry 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 | Apr 12–Apr 19 |
| Estimated harvest | Apr 11 '29–Apr 18 '29 (First real harvest the season after planting) |
Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 5-6 ft.
Raspberries are the best value fruit in a garden: cheap to buy as bare-root canes, hardy to zone 3, and producing fruit that costs an absurd amount in a shop and goes mouldy on the way home.
How raspberry fits zone 5's season
Zone 5b's frost-free window runs about 148 days, from May 10 to October 5. Raspberry takes about 1 growing season to reach first worthwhile harvest, so what matters here is how many of these seasons it gets, not whether one is long enough.
Raspberry is hardy in zones 3-8, so in zone 5b it stays in the ground through winter and comes back rather than being replanted. Allow about 2 ft of spread at maturity.
