Growing broccoli in zone 7
Broccoli buttons (makes tiny heads) if transplants sit through hard freezes or hit heat too young — timing matters more than for most crops. After the central head, most varieties produce weeks of side shoots.
Zone 7 covers upper South (Virginia, Tennessee, Oklahoma), New Mexico highlands — long season with mild winters — overwintering hardy greens becomes realistic. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

These windows use zone 7's typical frost dates (last frost ~Mar 30, first frost ~Nov 3). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.
Frequently asked questions
When do I plant broccoli in zone 7?
Transplant Mar 9 – Mar 23, counted from zone 7's typical last frost around Mar 30. As a hardy crop it tolerates the light frosts on either side of that window.
When should I start seeds indoors for broccoli in zone 7?
Sow indoors Feb 9 – Feb 23 — that's 7 to 5 weeks before the typical Mar 30 last frost, giving sturdy transplants exactly when the garden is ready for them.
Can I direct sow broccoli in zone 7?
Not usefully in zone 7 — broccoli needs more growing time than direct sowing allows, which is why it's raised from transplants started indoors Feb 9 – Feb 23.
Can I plant broccoli for a fall harvest in zone 7?
Yes — sow Jul 28 – Aug 11, counted back from the typical Nov 3 first frost so plants mature before serious cold. Light fall frosts improve flavor rather than ending the crop.
