Free PDF, personalized for your town's frost dates & climate. Drop your email — we'll send the link.

Mitchell has a classic four-season growing climate (Zone 7a). The last spring frost typically lands around May 23 and the first fall frost arrives around September 23 — a 123-day frost-free season that's long enough for tomatoes, peppers, melons, and a full succession of cool-weather crops on either side. The trick is timing: start warm-season seedlings indoors 6–8 weeks before last frost, harden them off, and plant out the week after your local frost date is statistically safe.

Mitchell averages 33.6 drought weeks per year (US Drought Monitor, 2000–present, trend stable). Treat irrigation as a year-round system, not a summer add-on.
