Growing lettuce in zone 5

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 5 covers southern New England, Great Lakes, Iowa, Nebraska, Colorado Front Range — a classic four-season garden climate with room for spring and fall plantings. 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.
