Beetroot

Sun

Full sun is best; tolerates light partial shade, but roots develop more slowly.

Water

Keep the soil evenly moist, especially during germination and root swelling; avoid prolonged saturation.

Soil

Loose, well-drained soil enriched with mature compost; ideally pH 6.0-7.5. Remove stones and break up compacted soil before sowing.

Height

1-2 ft (0.3-0.6 m) in leaf

Spread

0.5-1 ft (0.15-0.3 m)

Flowers

If left for a second year, produces small greenish flowers on tall stems in late spring or summer; normally harvested before flowering.

Foliage

Broad, slightly crinkled green to burgundy leaves, often with red veins and stalks.

Growth

Fast; many varieties reach harvest size about 8-12 weeks after sowing, depending on conditions.

Care needed

Low

• Edible

Northern hemisphere months. In Australia, shift them by six.

Growth rate

Fast

• Thin seedlings to 3-4 in (8-10 cm) apart for medium-sized roots; many seed clusters produce several seedlings.
• Water deeply during dry spells so growth stays steady and roots remain tender.
• Work mature compost into the bed before sowing; avoid fresh manure and excessive nitrogen fertiliser.
• Apply a thin mulch once seedlings are established, keeping it clear of their crowns.
• Weed gently by hand or shallow hoeing to avoid damaging the roots.
• Harvest most round varieties when roots are about 1.5-3 in (4-8 cm) across, before they become oversized.

Pruning. No pruning is needed. Pick a few outer leaves for salads or cooking once plants are established, leaving most foliage intact so the roots continue to grow.

Harvest beetroot roots about 8–12 weeks after sowing, when the shoulders visible above the soil are roughly 4–8 cm (1½–3 inches) across; smaller roots are also edible. Pull gently or loosen with a garden fork, ideally before prolonged heat or hard freezes make roots deteriorate. Pick young outer leaves for salads or cooking, taking only a few from each plant and leaving the central leaves to keep the root growing.

Early spring

Prepare a loose, compost-enriched seedbed; sow once the soil is workable and warming, using fleece if needed.

Spring

Thin crowded seedlings and keep the seedbed moist while young roots establish.

Late spring

Make another sowing for a staggered harvest rather than a single large crop.

Summer

Water during dry weather and harvest roots as they reach kitchen size; avoid sowing during extreme heat.

Late summer

Sow an autumn crop where enough mild growing weather remains; in hot climates, begin the main cool-season crop as temperatures ease.

Autumn

Lift mature roots before sustained hard freezes, or protect a short-term outdoor supply with mulch in mild areas.

Winter

Check stored roots for decay; in frost-free climates, continue harvesting cool-season crops.

• Plant in neat blocks or rows in a potager, using coloured stems and leaves to contrast with green lettuces.
• Edge raised vegetable beds with compact rows that are easy to thin and harvest.
• Grow in containers at least 10-12 in (25-30 cm) deep on a sunny patio.
• Use burgundy-leaved varieties among edible flowers and herbs for foliage colour in an edible border.

Garden styles it suits: Potager (kitchen garden), Edible landscape, Cottage garden, Homestead, Small-space and Family-friendly.

Plant it with: Lettuce, Spring onions, Radishes, Dill and Calendula.

Wildlife: Leaves provide food for some moth larvae and other insects. Plants allowed to flower can feed small visiting insects, but an annually harvested crop offers little nectar or pollen.

• Leaf miners leave pale blotches or tunnels in leaves: remove affected leaves and use fine insect mesh over young crops, rotating away from previously infested beds.
• Slugs and snails damage seedlings: check after dark, remove hiding places and use barriers or locally approved iron-phosphate bait if needed.
• Cercospora leaf spot causes small tan spots with darker margins: improve spacing, water at soil level, remove infected debris and rotate crops.
• Small or woody roots often follow crowding, drought or late harvesting: thin promptly, maintain even moisture and harvest while roots are young.

Roots and leaves are edible for people. Beetroot is not known to be poisonous to cats, dogs or horses in ordinary small amounts. Leaves contain oxalates, so large quantities should not be fed to pets or livestock; people advised to limit dietary oxalates should also moderate them.

• Swiss chard (Beta vulgaris (Leaf Beet Group))

  The same species, selected for large leaves and thick stalks rather than a swollen edible root; young plants can be difficult to distinguish.

• Turnip (Brassica rapa (Turnip Group))

  Usually has rougher, hairy or lobed leaves and often a white root with a purple shoulder, rather than beetroot's smoother, frequently red-veined leaves.

• Sugar beet (Beta vulgaris (Sugar Beet Group))

  Another form of the same species, usually producing a much larger, elongated white root and green leaves; seedlings may be indistinguishable.

Beta is the Latin name for beet, vulgaris means common, and beetroot refers to the swollen root harvested for food.

Propagation. Direct-sow seed clusters about 0.5-1 in (1-2.5 cm) deep in rows 12 in (30 cm) apart, then thin seedlings. Sow small batches every 2-3 weeks during suitable cool-to-mild weather. Beetroot can cross-pollinate with chard and other beets when flowering, so saved seed may not come true.
