How to Grow Beets

Growing guide

Overview

Beets are a cool-season root vegetable that produces both edible roots and leafy greens. Gardeners value them because they are fast, frost-tolerant, and easy to grow in spring. They need full sun, consistent moderate moisture, and loose, well-drained soil.

Soil & planting prep

Beets grow best in loamy, sandy, well-drained soil with a pH between 6.0 and 7.5. Before planting, loosen the bed 8-10 inches deep and work in compost, removing stones and hard clods. Space rows 12-18 inches apart, sow seed clusters about 1/2 inch deep, and thin plants to 3-4 inches apart.

When to plant

Direct sow beets outdoors 2 to 4 weeks before your average last frost date, when the soil is workable and at least 40°F. Beets are frost-tolerant, so light frost will not kill young plants. Make succession sowings every 2 to 3 weeks through late spring for a steady harvest.

How to plant

1. Loosen the soil 8-10 inches deep and mix in 1-2 inches of compost; remove rocks and break up clods so roots can swell evenly.
2. Direct sow beet seed clusters 1/2 inch deep and 1-2 inches apart in rows spaced 12-18 inches apart.
3. Water the seedbed gently and keep the top inch of soil moist until seedlings emerge, usually in 5-10 days.
4. When seedlings are about 2 inches tall, thin to one plant every 3-4 inches by snipping extras at soil level; pulling can disturb remaining roots.
5. Apply a light mulch and water evenly through the season; side-dress with compost or a balanced fertilizer if growth slows.

5 common mistakes to avoid

• Skipping thinning is a common beet failure because each seed cluster sends up several seedlings; when seedlings reach 2 inches tall, snip extras so remaining plants stand 3-4 inches apart.
• Letting soil dry out between waterings causes beets to turn woody and cracked; check soil regularly and provide about 1 inch of water per week during dry spells.
• Planting beets in heavy or rocky soil without loosening it leaves roots stunted and forked; loosen the bed at least 8-10 inches deep and remove stones before sowing.
• Overfeeding with high-nitrogen fertilizer or fresh manure pushes leafy tops at the expense of roots; use compost or a balanced fertilizer instead.
• Waiting too long to harvest makes roots woody and less sweet; pull beets when they reach 1.5-3 inches across, typically 50-70 days after sowing.

Harvesting & storage

Beets are ready when roots are 1.5-3 inches in diameter, usually 50-70 days from sowing; young leaves can be picked earlier. Loosen the soil with a garden fork and lift roots by the tops, then twist off greens about 1 inch above the crown. Store unwashed roots in the refrigerator for several weeks and use greens within a few days.

Companion planting

Good companions include onions, garlic, lettuce, bush beans, and cabbage-family crops such as broccoli and kale. Avoid planting beets with pole beans, which can shade the low-growing roots and compete for space.

Growing in containers

Beets are container-friendly; use a pot at least 5 gallons and 10-12 inches deep. Fill with loose, well-drained potting mix, sow seeds 1/2 inch deep, thin to 3-4 inches apart, and keep the mix evenly moist.

Pro tips

Direct sow in early spring — beet seeds are clusters so thin to one plant per cluster. Harvest roots at golf-ball size for best flavour. Greens are edible at any stage.
