Soil & site
Rich, warm soil heavy with compost. Steady water keeps fruit from turning bitter.
Seedling care
Direct sow after soil warms; transplants sulk and rarely catch up.
Growing notes
Trellis them — straighter fruit, better airflow, easier picking. One missed yellow cucumber signals the vine to shut down, so pick clean.
Harvest
Daily, at slicing size. They hide under leaves; check twice.
