Botanical Name: Beta vulgaris
Days to Maturity: 48 days
Native: Europe, Asia, and the Mediterranean region
Hardiness: Frost-tolerant biennial grown as an annual
Plant Dimensions: Leaf tops are 18″ tall
Variety Information: Smooth, 1 ½”–2 ½;” diameter with slightly flattened roots. Leaf tops are dark green on red stems. ‘Early Wonder’, introduced in 1911, is an excellent beet for both greens and roots, ready for harvest in as little as 40 days. Especially good in early spring due to its ability to grow in cool soils.
When to Sow Outside: RECOMMENDED. 2 to 4 weeks before your average last frost date, when soil temperature is at least 45°F, ideally 60°–85°F, for early summer crop. 6 to 8 weeks before your average first fall frost date for late summer/fall crop. Mild Climates: Sow fall through winter.
When to Start Inside: Not recommended. Root disturbance delays maturity.
Days to Emerge: 5 – 21 days
Seed Depth: ½”
Seed Spacing: 1 seed every 4″
Row Spacing: 12″
Thinning: When 2″ tall, thin to 1 every 4″
Harvesting: For early spring sowings, harvest beets before summer heat. For late summer sowings, harvest before first heavy freeze. For winter sowings in mild climates, harvest in early spring. Harvest when roots are anywhere from 1″â€”3″ in diameter. The smaller they are, the more tender. Greens are most tender when small, so start harvesting when they are 2″ tall. You can take as much as one third of a beet plant’s outer leaves without harming the root crop.
