Dark Red Detroit Beet Seeds

Detroit Dark Red Beet seeds for planting do best in cool weather, so sow them 4–5 weeks before the last spring frost or again 4–5 weeks before the first fall frost. Plant seed 1/2 inch deep in loose soil, spacing seeds 1–2 inches apart, then thin seedlings to 3–4 inches once they have a set of true leaves, with about 12 inches between rows. Beet Detroit Dark Red seeds germinate in about 5–14 days when soil stays in the 55–70°F range. It can be useful to soak seeds for 24 hours before sowing to speed things up. 

Detroit Beet seeds need full sun for reliable growing, though part shade still works, especially in warmer areas. Loose, sandy to loamy, well-drained soil is perfect, because roots need room to swell evenly; tight ground gives you stunted beets with more top than root. Aim for soil around pH 6.0–7.0 and keep moisture steady rather than swinging from dry to soaked. A light mulch helps hold moisture, cool the root zone, and keeps the bed from crusting over.

Once seedlings establish, thin them, since crowded plants fight for space, and thus have small roots. Go easy on high-nitrogen fertilizer too, as it pushes leafy tops and shortchanges the root.

Harvest usually starts in 55–60 days. You can begin pulling once the shoulders show above the soil and roots reach about 1 inch across, though they stay tender up to around 3–4 inches. The tops are useful too: pick young greens at 2–3 inches for salads, or cook larger leaves like swiss chard. For storage, pull mature roots carefully from loose soil and use them fresh, pickled, canned, blanched, or frozen.
