Transplant Butterhead Lettuce (spring)
Cool-season crop — can go out before last frost.
Space 10—12" apart.

Season Insights
End-of-season recap
Butterhead Lettuce
Greens & Salads
91% watered
Harvest Aug 18 · +2d late (GDD)
Warm season — +8% GDD vs avg
GDD harvest estimate was accurate to 2 days
Heat units tracked across 94 days from transplant. Zone 6a accumulated 641 GDD vs 593 typical — a warmer-than-average season.
Excellent watering consistency
91% of scheduled waterings completed. Only 2 missed windows all season. No measurable yield impact detected.
Earlier transplant recommended next year
Season compression was detectable in final 3 weeks. Planting 7 days earlier would avoid the late-August GDD slowdown in Ann Arbor, MI.
Romaine Lettuce
Greens & Salads
63% watered
Harvest Sep 4 · +11d late (est.)
Cool finish
3 high-consequence windows missed mid-season
Skipped tasks scored 6–7/10 impact — transplant timing and a critical feeding window. Harvest shifted 11 days. Prioritize July tasks next season.
Cool August stalled ripening
GDD accumulation slowed in the final 3 weeks of the season. Not something you could have controlled — just useful context for next year’s timing.
