Goji Berry in Zone 6a & 6b
Lycium barbarum
When to plant goji berry 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. Goji Berry 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 11–Apr 18 |
| Estimated harvest | Apr 10 '29–Apr 17 '29 (First real harvest in year 3) |
Spacing: about 20 square feet per plant (square-foot-gardening spacing). Mature height: 3-6 ft.

Goji berry, also called wolfberry, is a relative of tomato and pepper that shares some of their cultural needs, notably a taste for slightly alkaline soil rather than the acidic conditions most fruiting shrubs prefer.
How goji berry fits zone 6's season
Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Goji Berry 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.
Goji Berry is hardy in zones 4-7, so in zone 6b it stays in the ground through winter and comes back rather than being replanted. Allow about 5 ft of spread at maturity.
