Growth Stages

1

Germination & Seedling

7-14 days

Seeds sprout in 7-10 days with true leaves emerging. Each seed pod contains 2-4 seeds, resulting in clusters of seedlings.

Keep soil consistently moist but not soggy. Thin seedlings to 3-4 inches apart when they have 2-3 true leaves to reduce competition. Save thinned greens for salads.

2

Vegetative Growth

20-30 days

Foliage develops with 5-8 green leaves per plant; roots begin bulbifying underground. Aboveground growth is slow while root development accelerates.

Water consistently to maintain evenly moist soil. Apply 1-2 inches of mulch around plants to retain moisture and regulate soil temperature. Avoid nitrogen-heavy fertilizer (promotes greens over root development).

3

Root Development & Enlargement

25-40 days

Roots swell to mature size (2-3 inches diameter). The characteristic dark red color develops fully. Greens continue to grow but growth slows as energy shifts belowground.

Continue consistent watering to prevent cracking. Avoid over-fertilizing. Monitor for pests. Roots are ready when tops of roots begin showing above soil surface (typically 2-3 inches of shoulder visible).

4

Harvest & Storage Readiness

Ready at 55-70 days; can be harvested slightly earlier for tenderness

Roots reach 2-3 inches diameter with deep crimson color and firm flesh. Greens darken and may show reddish veining. Plant is fully mature.

Harvest when roots are tender and sweet (smaller roots are often sweeter than very large ones). Avoid letting roots get too large as they become woody and lose flavor. Pull gently or loosen with a fork before pulling.

Harvest Tips

Harvest when roots are 2-3 inches in diameter (typically 55-70 days). For baby beets, harvest at 1-1.5 inches. Grasp at soil line and pull gently, or loosen soil with a garden fork first. Twist off greens 1-2 inches above the root to prevent bleeding. Store roots unwashed in cool (32-40°F), humid conditions for up to 3-4 months. Can also be pickled or preserved. Greens are best used fresh within 2-3 days of harvest.

Fun Facts
