Plum in Zone 7a & 7b
Prunus domestica
Yes, plum grows in zones 7a and 7b and comes back each year. Set out nursery plants Mar 27–Apr 3.
When to plant plum in zone 7b
Zones 7a and 7b 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 | Mar 27–Apr 3 |
| Estimated harvest | First real harvest in year 5 |
Spacing: about 50 square feet per plant (square-foot-gardening spacing). Mature height: 15-18 ft.
Before you plant: Plum has a winter-hardiness note for zone 7b. See the details below.

European plum (Prunus domestica), the species most home orchards grow, is generally self-fertile, meaning a single tree sets a full crop alone. That's a real advantage over apple and pear, which is worth knowing before assuming every fruit tree needs a pollination partner. Japanese plum is a separate species, usually needing a cross-pollinator, and isn't what this profile covers.
How plum fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Plum takes about 4 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.
Plum is hardy in zones 4-8, so in zone 7b it stays in the ground through winter and comes back rather than being replanted. Allow about 16 ft of spread at maturity.
