Frost likely Frost possible Frost unlikely Frost is likely until April 19 and fades out by May 9. It is unlikely from then until September 17, and likely again after October 12. The dashed lines are the typical dates, May 1 and September 29.

Your season is too short for a separate fall planting of cabbage: sown late enough to be a fall crop, it wouldn't be ready before the typical first frost. Your spring planting is your harvest.
