Timing shifts with your zone — the Genie can pin down exact dates for you.
How to care for it
Grown from slips, not seed — start slips indoors or buy starts. Plant only once soil is thoroughly warm; vines ramble 6+ ft, so give them the bed's edge. Dig before frost and cure 10 days warm for sweetness.
Good companions
Bush bean, okra
Harvest
Dig when leaves yellow and frost approaches, 90-120 days.
