Soil & site
Deep, loose, sandy loam free of rocks. Skip fresh compost or manure — rich clumps cause forked, hairy roots.
Seedling care
Germination is slow (1–3 weeks) and the bed must never dry out. A board or burlap over the row until sprouts appear keeps moisture in — check daily.
Growing notes
Thin ruthlessly to 2–3 in; crowded carrots stay skinny. Rows 12–18 in apart.
Harvest
Fall carrots kissed by frost are the sweetest of the year. Mulch deeply and harvest straight through winter.
