Windows use zone 3's typical frost dates (May 15 / Sep 20). For your own city's dates, run the frost lookup — the planting calendar then localizes everything automatically.
16 crops can go in the ground: peas, lettuce, spinach, kale, swiss chard, collard greens, kohlrabi, carrots, and 8 more. Exact windows are in the tables above — early and late in the month can differ by a full frost date.
The spring window has passed; tomatoes set out this late won't beat the Sep 20 average first frost to ripeness. Plan for next spring's seed-starting instead.
