Early Round Dutch Cabbage Seeds

Start Dutch Cabbage seeds indoors 6–8 weeks before your last frost date, sowing 1/4 inch deep in moist seed-starting mix. At soil temperatures between 45–85°F, germination typically takes 7–14 days. Once two sets of true leaves appear, move seedlings into individual cells so roots have room to develop without competition. Before transplanting outdoors, harden them off for about a week: set them outside in a sheltered spot for a few hours each day, gradually increasing exposure. For a fall crop, count back 10–12 weeks from your first expected frost and transplant. Fall-grown heads often have better flavor than spring ones, since cool nights concentrate the sugars in the leaves.

Dutch Cabbage needs at least 6–8 hours of direct sun daily. It tolerates a bit of shade, but shaded plants produce looser, smaller heads. Soil should be rich, fertile, and well-draining; work compost into the bed before planting. Keep pH between 6.0 and 6.8. Water regularly and evenly throughout the growing season. Uneven moisture during head formation leads to cracked or split heads after the first heavy rain. Apply mulch around the base to help hold moisture and keep soil temperature stable during warm spells.

Space plants 12–18 inches apart in rows 18–24 inches apart. Crowding is one of the most reliable ways to get small, deformed heads. Add row covers from transplanting to avoid cabbage worms. Rotate brassicas every two years minimum. Skipping crop rotation leads to clubroot and other soil-borne diseases. Harvest once heads feel firm and solid when squeezed.
