Apple in Zone 4a & 4b
Malus domestica
When to plant apple in zone 4b
Zones 4a and 4b 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. Apple 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 | May 1–May 8 |
| Estimated harvest | Apr 30 '30–May 7 '30 (First real harvest in year 4) |
Spacing: about 50 square feet per plant (square-foot-gardening spacing). Mature height: 15-20 ft.
Apple trees sold by nurseries are grafted, not grown from seed, and almost every variety needs a second, different apple variety (or a compatible crabapple) blooming nearby to fruit at all. This first-pass profile covers spacing and pollination; a full grow-guide covering pruning, thinning, and disease management is planned as a follow-up.
How apple fits zone 4's season
Zone 4b's frost-free window runs about 128 days, from May 15 to September 20. Apple 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.
Apple is hardy in zones 3-8, so in zone 4b it stays in the ground through winter and comes back rather than being replanted. Allow about 18 ft of spread at maturity.

Where to buy apple starts
Apple 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.
