Beets — beetroot — are a two-for-one crop: sweet, earthy roots for roasting and pickling, plus tender young leaves that cook like spinach. They are easy to grow, they store well, and a row of beets in deep red, gold or striped varieties is one of the prettiest sights in the vegetable garden.
Beets are a cool-season root crop that likes loose soil and steady moisture.

Starting seeds
This is a direct-sow crop: the seed goes straight into the garden where it is to grow, and the plants are not transplanted. Prepare a fine, weed-free seed bed, sow at the depth shown on the seed packet, and keep the bed evenly moist until seedlings appear — expect germination in 7–14 days.
Sow too early into cold, wet soil and germination stalls; sow too late and the plants run out of season. Use our frost-date calculator and the hardiness-zone finder to place your sowing window. Zones 11–13 are frost-free, so sowing windows there are set by heat and rain rather than frost — check your local extension service.
Beets are sown direct where they are to grow — their roots do not transplant. Each beet seed is actually a cluster that produces several seedlings, so sow thinly and thin each clump to a single plant at the proper spacing once seedlings are a few centimetres tall. The thinnings are edible as salad leaves. Keep the seed bed moist until seedlings appear.
Transplanting and planting out
Beets are not transplanted, so the work at this stage is thinning. Thin each cluster to one seedling at the proper spacing, and thin again if needed so each root has room to swell — crowded beets stay small. Water the row before thinning so the seedlings come out easily, and do the job in the evening to avoid stressing the plants you leave behind.
Space plants 3–4 inches apart — crowding is one of the commonest causes of small harvests. Our plant-spacing calculator works out how many plants fit your bed.
Soil and feeding
Beets grow best in rich, well-drained soil with plenty of organic matter. Dig in compost before planting: it improves heavy soil, helps light soil hold moisture, and feeds the soil life that feeds your plants. Aim for a soil pH of 6.0–7.0 — a simple soil test will tell you where you stand, and garden lime or sulfur can nudge pH up or down over a season, so test before you amend rather than guessing.
Feed lightly and steadily rather than in one heavy dose: too much fast nitrogen late in the season pushes leafy growth at the expense of the part you eat. Our fertiliser calculator works out amounts for your bed size, and the soil-volume calculator tells you how much mix a new bed needs.
Watering
Water needs are moderate: keep the soil evenly moist, watering deeply when the top inch or two dries out. Deep, infrequent watering builds deeper roots than a daily sprinkle.
Water at the base of the plant, in the morning, so the leaves dry quickly and the water reaches the roots. Our watering calculator gives a starting point for your bed size, and the watering schedule generator can build a routine around it. A mulch layer cuts evaporation and keeps moisture even.
Sunlight and temperature
Beets need full sun — a spot that gets sun for most of the day. Our sunlight calculator can check your spot.
This crop is rated hardy for cold tolerance, so it stands up to frost and even light freezes, and it is at its best in the cool seasons. In Zones 11–13, which are frost-free, heat rather than cold is the limit — grow it in the cooler months, with afternoon shade in the hottest weather. Our hardiness-zone finder will confirm your zone, and the frost-date calculator gives you the frost dates to plan around.
Pests and diseases
The pests and diseases most often reported on beets are aphids, slugs, cutworms. Healthy, well-watered plants resist attack better than stressed ones, and rotating beds so the Amaranthaceae family does not repeat in the same spot helps keep soil-borne problems down.
- Aphids — small sap-sucking insects on new growth; wash off with a strong jet of water and encourage ladybirds.
- Slugs — chew ragged holes in leaves at night; water in the morning so the surface dries by evening.
- Cutworms — caterpillars that chew through young stems at soil level; a cardboard collar around each stem protects it.
Inspect plants weekly, especially leaf undersides, and act early. Our pest-identifier helper can help identify what you are seeing.
Companion plants
Good companion plants for beets include:
- Marigolds — their roots discourage some soil pests
- Basil — attracts pollinators
- Onions — their scent is said to confuse pests
- Lettuce — shallow-rooted, fills gaps without competing
Our companion-planting finder can suggest more pairings for your bed plan.
Harvesting
Pull beets when the roots are a useful size — check by brushing the soil away from the top of a root. Young beets are sweet and tender, while larger roots are good for roasting and storing. Twist the tops off rather than cutting them, leaving a short stalk so the root does not bleed, and lift the remaining roots before the ground freezes. The young leaves are edible too — cook them like spinach.
Expect the crop to be ready about 50–70 days after sowing, though weather and variety shift that window by a week or two either way. Our harvest-date calculator works out your expected harvest date from your sowing date, and the vegetable-yield estimator can estimate how much a bed should produce.
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Small roots | crowding, or dry soil while roots swell | Thin each seed cluster to one plant at the proper spacing, and keep the soil moist while the roots are swelling. |
| Woody or tough roots | heat or drought stress | Keep beets evenly watered and mulch to hold the moisture. |
| Poor germination | the seed bed drying out, or cold soil | Beet seed needs warm, moist soil to germinate well. |

Poor germination
Beet seed needs warm, moist soil to germinate well.
Frequently asked questions
When should I plant beets?
Sow once the soil is workable in spring — this crop is rated hardy for cold tolerance, so it can go in early. For zone-specific timing, see zone 3 or zone 6, and check your local extension service for the dates that fit your area.
How long do beets take to grow?
Beets take 50–70 days from sowing to maturity, and seed germinates in 7–14 days. Weather and variety shift the harvest window by a week or two, so judge readiness by look and feel rather than the calendar alone.
How far apart should I plant beets?
Space plants 3–4 inches apart — that is the room a mature plant needs, and crowding means poor airflow and small harvests. Our plant-spacing calculator works out how many fit your bed.
Can I eat beet leaves?
Yes — young beet leaves are tender and delicious, cooked like spinach or eaten raw in salads when small. Pick a few outer leaves from each plant without harming the root, or use the thinnings from your first thinning.
