Growing notes

Carrots need steady, even moisture — roughly 1 inch per week — especially during the slow germination stretch, when the seedbed must never crust over or dry out. Keep the surface consistently damp for the two to three weeks it takes for seeds to sprout; a light board or burlap laid over the row holds moisture until germination. Once established, water deeply to encourage roots to grow long and straight rather than forking toward shallow moisture. Erratic wet-then-dry swings cause the roots to split, crack, or turn woody. A light mulch between rows steadies soil moisture. Ease off slightly as roots near maturity, since too much late water can crack them.
