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.
Astro Arugula
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.
Recent Activity
Rain forecast 0.8” — watering skipped for Butterhead Lettuce. NWS 80% chance through tonight.
Feeding completed — Butterhead Lettuce. Calcium boost applied. Blossom end rot risk flagged last week.
Astro Arugula showing lower-leaf yellowing — marked as struggling. Triage: possible nitrogen deficiency.
Watering completed — Astro Arugula. Soil moisture looked good before scheduled task.

Fall 2026
Summer 2026
Bolted — the spring romaine finally gave up. 5 nights above 68°F with daytime highs in the 80s. Pulled the row, prepping for the summer heat break.
84°FJul 8, 2026
Third lettuce succession in — 2-week interval is keeping the rotation tight. Butterhead and oakleaf this round.
72°FJun 12, 2026
Spring 2026
First spinach sown directly — Ann Arbor last frost is around May 3, but spinach handles cold and the soil hit 45°F. Started 3 weeks early on this row.
