Beloit, OH — Planting Guide for July

Download My Garden Planner for Beloit

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

Beloit has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around April 30 and the first fall frost arrives around October 18 — a 171-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.

Drought pressure is moderate (10.0 weeks/year on average). Mulching and drip irrigation pay for themselves quickly.
