Growing kohlrabi in zone 8
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 8 covers deep South, central Texas, coastal Pacific Northwest — two full gardens a year — a spring/summer garden and a serious fall/winter one. 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 8's typical frost dates (last frost ~Mar 15, first frost ~Nov 15). 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.
