Beets trace their ancestry to the Mediterranean region, where their leafy tops were eaten long before the swollen roots became a familiar table vegetable. Today’s garden beets may be round, flattened, cylindrical, red, golden, white, or boldly striped, and both the roots and tender leaves are useful in the kitchen.
Closely related to Swiss chard, beets are cool-season biennials grown for harvest during their first year. They develop their best color, sweetness, and texture in loose soil with steady moisture and mild temperatures, moving quickly from clustered seedlings to tender roots ready for the table.
Growing Guide
Timing
Direct sow beets about 2–4 weeks before the expected last spring frost, once the soil can be worked and has warmed to about 45–50°F.
Make small sowings every 2–3 weeks for a longer harvest. For fall crops, sow early enough to allow about 55–70 days before the first hard freeze. Beets tolerate light frost and often become sweeter in cool weather.
Sowing & Starting
Sow seed clusters about ½ inch deep and 1 inch apart in loose, well-drained soil. Keep the seedbed evenly moist until seedlings emerge.
Because each corky “seed” may produce several seedlings, thinning is usually necessary. Space plants about 3 inches apart for most varieties, or slightly wider for large and cylindrical types. Young thinnings are edible.
Growing & Care
Choose a site with full sun to light afternoon shade and soil that has been loosened deeply enough for roots to form without obstruction.
Keep moisture steady and mulch lightly once seedlings are established. Avoid heavy nitrogen, which can produce large tops and smaller roots. Weed shallowly because beet roots are easily disturbed near the soil surface.

Nutrition & Uses
Beet roots provide fiber, folate, potassium, and manganese. Red and golden varieties contain betalain pigments, which give the roots their rich color and antioxidant activity.
Roots may be roasted, steamed, pickled, fermented, grated raw, or added to soups. Young leaves can be cooked like Swiss chard or spinach.
Pests & Diseases
Leafminers may leave pale tunnels or blotches in the leaves. Remove affected leaves and use insect netting early in the season where they are a recurring problem.
Flea beetles, aphids, and cutworms may also damage young plants. Crop rotation, clean beds, healthy soil, and regular inspection usually prevent serious losses. Good spacing and watering at soil level help reduce leaf spot diseases.
Seed Saving
Beets are biennial and wind-pollinated. They cross readily with other beet varieties, Swiss chard, sugar beets, and mangels, so only one flowering type should be grown nearby when saving pure seed.
Select healthy, true-to-type roots and overwinter them in the ground where winters are mild, or lift and store them in cool, humid conditions. Replant in spring, allow seed stalks to mature and dry, then cut, thresh, clean, and store the seed in a cool, dry place.
Extra Tips
Soak seed clusters for a few hours before sowing to encourage even emergence.
