Growing notes

Beets need steady, even moisture — about 1 inch of water per week — to grow tender roots without cracking. The most critical stretch is germination, when the seedbed must stay consistently damp for the one to two weeks it takes the seed clusters to sprout; if the surface crusts and dries, emergence is patchy. Once seedlings are up, water deeply and regularly rather than in light sprinkles, encouraging roots to swell smoothly. Inconsistent watering — long dry spells broken by a heavy soak — makes roots crack, split, or develop tough, woody zones and white rings. A light mulch between rows steadies soil moisture and buffers heat. Ease off only slightly as roots approach harvest size.
