Grape in Zone 4a & 4b
Vitis spp.
Yes, grape grows in zones 4a and 4b and comes back each year. Set out nursery plants Apr 24–May 1.
When to plant grape in zone 4b
Zones 4a and 4b share the same average frost dates, so this page covers both.
Method: Buy as a start: Buy as a nursery start and transplant outside. It's 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 24–May 1 |
| Estimated harvest | First real harvest in year 3 |
Spacing: about 50 square feet per plant (square-foot-gardening spacing). Mature height: 6-10 ft.
Before you plant: Grape has a winter-hardiness note for zone 4b. See the details below.

A grape vine is the largest thing on this site. One vine covers eight feet of fence or more, lives for decades, and needs one job from you each winter: a hard prune, without which you get a wall of leaves and no grapes.
How grape fits zone 4's season
Zone 4b's frost-free window runs about 128 days, from May 15 to September 20. Grape 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.
Grape is hardy in zones 4-10, so in zone 4b it stays in the ground through winter and comes back rather than being replanted. Allow about 8 ft of spread at maturity.

Where to buy grape starts
Grape is almost always bought as a nursery start rather than seeded. Check a local nursery or garden center; we haven't vetted online start/plant suppliers yet.
