Mulberry in Zone 7a & 7b
Morus rubra
When to plant mulberry in zone 7b
Zones 7a and 7b 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. Mulberry 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 10–Apr 17 |
| Estimated harvest | Apr 9 '30–Apr 16 '30 (First real harvest in year 4) |
Spacing: about 50 square feet per plant (square-foot-gardening spacing). Mature height: 10-20 ft.
Mulberry is a large, fast-growing native shade tree that also happens to produce sweet, blackberry-like fruit, prized by birds and other wildlife as much as by the people who plant it.
How mulberry fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Mulberry takes about 3 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.
Mulberry is hardy in zones 4-9, so in zone 7b it stays in the ground through winter and comes back rather than being replanted. Allow about 8 ft of spread at maturity.
