Growing green beans (bush) in zone 4
Direct-sow after frost in warm soil — seed rots in cold, wet ground. Bush beans produce in a concentrated 2–3 week window, so sow a fresh row every few weeks. Pick constantly to keep plants producing.
Zone 4 covers northern Plains, northern New England, much of Montana and Wyoming — about 150 frost-free days — most vegetables work, long-season melons are a stretch. 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 4's typical frost dates (last frost ~May 5, first frost ~Oct 1). 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.
