Goji Berry in Zone 5a & 5b
Lycium barbarum
When to plant goji berry 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. 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 26–May 3 |
| Estimated harvest | Apr 25 '29–May 2 '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 5's season
Zone 5b's frost-free window runs about 148 days, from May 10 to October 5. 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 5b it stays in the ground through winter and comes back rather than being replanted. Allow about 5 ft of spread at maturity.
