Growth Stages

1

Seedling

2-3 weeks

Beet seeds germinate in 7-14 days. Seedlings emerge with oval cotyledons followed by true leaves with distinctive red veining.

Keep soil consistently moist but not soggy. Thin seedlings when 2-3 inches tall, keeping strongest plants. Thinned seedlings are edible.

2

Vegetative

3-4 weeks

Young plants develop a rosette of green leaves with prominent red stems and veining. Foliage is lush and bushy.

Continue consistent watering. Apply mulch around plants to retain moisture and regulate soil temperature. Monitor for weeds and thin further if needed. Avoid excessive nitrogen which promotes foliage at the expense of root development.

3

Root Development

2-3 weeks

Roots begin swelling underground while foliage continues growing. Roots develop the characteristic dark red color and reach golf ball to tennis ball size.

Maintain even soil moisture to prevent root cracking and woody texture. Provide consistent, moderate watering. Avoid high nitrogen fertilizers. Side-dress with balanced fertilizer if soil is poor.

4

Maturation

1-2 weeks

Roots reach full size (2-3 inches diameter), with tender, sweet flesh. The foliage may start to yellow slightly at edges.

Continue watering to prevent rootiness. Roots can be harvested at baby stage (golf ball size) or left to full maturity. Begin checking root size by gently uncovering the top.

5

Harvest

Ongoing from day 50 onward

Mature roots are deep crimson-purple with dark red flesh, uniform in shape, and tender with excellent sweetness.

Pull roots gently when 2-3 inches in diameter for optimal tenderness, or allow to grow larger for storage. Twist off greens 2 inches above root, or leave intact for handling.

Harvest Tips

Harvest when roots are 2-3 inches in diameter (50-70 days) for peak tenderness, or allow to grow larger for storage varieties. Pull gently or dig carefully to avoid bruising. For baby beets, harvest at golf ball size. Store roots by twisting off greens 2 inches above root, then brush off excess soil. Unwashed beets store 4-6 months in cool (32-40°F), humid conditions. Beet greens are edible and delicious when young and tender.

Fun Facts

  • 🌱 Detroit Dark Red is an heirloom variety that has been cultivated since the 1800s and remains one of the most reliable and popular beet varieties worldwide.
  • 🌱 Beet greens are extremely nutritious and contain more vitamins and minerals than the roots themselves—they make excellent sautéed side dishes or raw salad greens when harvested young.
  • 🌱 The deep red color of Detroit Dark Red beets comes from betalains, powerful antioxidants and anti-inflammatory compounds that are unique to beets and are destroyed by prolonged cooking, making raw beets or lightly cooked preparations ideal for maximum nutrient retention.
