Growing kohlrabi in zone 7
Harvest bulbs at tennis-ball size — bigger gets woody. Kohlrabi matures fast enough to squeeze into gaps between other plantings in both spring and fall.
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.
