Growing Lettuce in Connecticut
Lettuce in Connecticut's Climate
Lettuce grows well in spring and fall but bolts when summer temperatures consistently exceed 80°F. Direct sow 4 weeks before your last frost and succession plant every 2 weeks until mid-May. Resume in August for fall harvest. Summer lettuce is possible with heat-tolerant varieties and afternoon shade, but expect shorter-lived plantings.
Soil Considerations for Connecticut
Rocky New England soil common. Acidic in many areas. Raised beds popular for dealing with rocky ground.
Connecticut Climate & Growing Season
Four distinct seasons. Maritime influence moderates coastal temperatures. Shorter growing season inland.
Growing season length varies across Connecticut: Northern Connecticut (5b, 6a) has a last frost around May 1 - May 15, while Coastal Connecticut (6b, 7a) sees frost end around Apr 15 - May 1. This difference matters for lettuce — adjust your planting dates to match your specific region.
Growing Tips
Succession plant every 2-3 weeks for continuous harvest. Shade cloth extends the season into warmer months.
