Growing lettuce in zone 6

Sow a short row every 2 weeks instead of one big planting — lettuce bolts quickly once heat arrives. Afternoon shade extends the spring season, and fall crops are often the sweetest.

Zone 6 covers mid-Atlantic, Ohio Valley, Kansas, inland Pacific Northwest — nearly 200 frost-free days — almost everything grows, and fall gardens are easy. 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.

Make it local

These windows use zone 6's typical frost dates (last frost ~Apr 10, first frost ~Oct 22). 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.
