Zucchini in Zone 7a & 7b
Cucurbita pepo
When to plant zucchini in zone 7b
Zones 7a and 7b share the same average frost dates in our data, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Zucchini tolerates either.
| Start indoors | Mar 20–Mar 27 |
|---|---|
| Direct sow / transplant outside | Apr 17–Apr 24 |
| Estimated harvest | Jun 6–Jun 13 (~50 days after planting) |
Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 2-3 ft.
Zucchini's reputation for overwhelming a garden is well-earned: a single healthy plant can produce more squash than most households can eat, which is exactly why our planting calendar puts just one plant per square foot rather than clustering several together.
How zucchini fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Zucchini needs about 50 days from sowing to first harvest.
Good companions
- Marigold: Marigolds deter squash bugs and beetles.
- Nasturtium: Nasturtium is a trap crop that draws aphids away from squash.
