How to grow beetroot

Beta vulgaris

Beetroot is one of the most reliable root crops for a UK garden. Sow direct in a sunny bed of light, fertile soil every three to four weeks from mid March to mid July, starting with a bolt-resistant variety, and thin the seedlings to 10 cm. Each seed is a cluster that gives several plants, so early thinning matters, and even watering keeps the roots tender. Pull them from golf-ball size, seven to eight weeks after sowing.

Sowing and planting beetroot

WhenSow Mar to Jul in succession (bolt-resistant types first); harvest Jun to Oct

Starting off

Direct from mid March (bolt-resistant 'Boltardy' first) to July, germinating in 10 to 14 days at 10 to 20 °C; soaking the corky seed clusters for an hour speeds it up. Modules at 15 °C in March, 3 seeds per cell, planted out in April give the earliest crop. Fleece sowings before April.

Spacing and planting

Sow 2 cm deep in drills 30 cm apart and thin to 10 cm for maincrop roots, 5 cm for baby beets; multi-sown modules of 3 to 4 seedlings go out 20 cm apart. Round types are excellent in a 20 cm deep pot or trough with 8 to 10 plants.

Varieties worth growing

Boltardy
The standard round red beet. Its resistance to bolting makes it the only sensible choice for sowings before mid April.
Pablo F1
Very smooth, uniform, sweet roots that stay tender at any size, the best for baby beets and for showing.
Chioggia
Italian beet with pink and white rings inside and a mild, sweet flavour. Best raw or roasted, as boiling fades the rings.
Burpee's Golden
Orange skin and yellow flesh that does not stain, with leaves good enough to cook as greens. Germination is weaker, so sow a little thicker.
Cylindra
Long, cylindrical roots that cut into even slices for pickling, give more weight per metre of row and store well.

Beetroot month by month

Timings are for central England. Allow two weeks later in the north and on cold, heavy soil.

  1. January

    Use stored roots. Order seed.

  2. February

    Put cloches out late in the month to warm the soil for the first sowing.

  3. March

    Sow Boltardy under cloches from mid month, or in modules indoors.

  4. April

    Plant out module clumps 20 cm apart. Sow direct. Keep fleece over early rows.

  5. May

    Sow every three to four weeks. Thin to 10 cm and eat the thinnings as salad leaves.

  6. June

    Pull the first baby beets, taking alternate roots. Sow again. Water in dry spells.

  7. July

    Last sowing by mid month for autumn roots to store. Potash top-dress on earlier rows as roots swell.

  8. August

    Pull as needed before roots pass tennis-ball size. Water evenly.

  9. September

    Pull as needed.

  10. October

    Lift the rest before hard frost, twist off the tops and store sound roots in boxes of damp sand.

  11. November

    Check stored roots and use any that are softening.

  12. December

    Use stored roots.

Feeding beetroot

A moderate feeder that wants potassium more than nitrogen. A light base dressing before sowing and one potash top-dress as the roots start to swell; heavy nitrogen gives leaf at the expense of root.

NNitrogenModerate
PPhosphorusModerate
KPotassiumHigh

Values potassium and boron; avoid heavy fresh nitrogen, which favours leaf over root.

Feeding plan

WhenWhatHow much

Autumn or winter before sowing

Garden compost

A 3 to 5 cm layer. No fresh manure in the beetroot year.

A week before sowing

Fruit & Vegetable Fertiliser 4-5-6

70 g/m², the lower end of the label, raked in: about 20 g per metre of row with rows 30 cm apart (70 x 0.3).

When the roots reach marble size

Sulphate of Potash 0-0-50

20 g/m², the bottom of the label range, once: about 6 g per metre of row (20 x 0.3), scattered between the rows and watered in.

Before sowing, only on light or recently limed soil where roots have had black, corky patches inside

Boron Humate Granules

1 to 2 g/m², a quarter to half a level teaspoon per square metre, once a season and never exceeded.

Signs to watch

Red-tinged, dull leaves and small roots

Nitrogen short on cold soil

Fleece and a balanced feed

Pests, diseases and problems

What you seeCauseWhat to do

Seedlings pecked off or pulled out as they emerge

Sparrows and other small birds, drawn to the red seedlings

Cover the row with fleece or fine netting from sowing until the plants have four true leaves.

Gaps in the row and seedlings eaten to the ground

Slugs

Sow in modules and plant out at 5 cm tall where slugs are bad, and keep the bed edges clear of weeds and debris.

Pale brown, papery blotches in the leaves with a small maggot between the leaf surfaces

Beet leaf miner, in two or three generations from May

Pick off and bin affected leaves or squash the maggot inside the blotch. The roots are unaffected unless seedlings are attacked heavily; insect mesh prevents it.

Small round spots with pale centres and purple-brown edges on older leaves

Fungal leaf spot in warm, wet weather

Remove the worst leaves, keep to the full spacing and rotate. It seldom affects the roots.

Rough, corky, raised patches on the skin of the root

Common scab, favoured by dry, light, alkaline soil

Add garden compost to hold moisture, water in dry spells and do not lime the bed before beetroot. Peel and eat: the flesh is unaffected.

Harvest and rotation

Harvest and storage

Pull baby beets at golf-ball size 7 to 8 weeks from sowing, maincrops at tennis-ball size at 11 to 13 weeks; twist off the leaves rather than cutting so the roots do not bleed. A 3 m row yields 4 to 5 kg. Store in boxes of damp sand in a cool shed until March, or pickle and freeze.

Rotation and companions

Rotation: beet family (Amaranthaceae, formerly Chenopodiaceae) with chard and spinach, 3-year gap, often grouped with roots; follows legumes or brassicas. Keep away from runner beans and sweetcorn, which cast too much shade, and from mustard, which hinders its growth.

Good to knowEach 'seed' is a cluster, sow thinly and thin early; keep evenly watered to avoid woody, ringed roots.

Growing beetroot in pots

Round beetroot is a good pot crop. Use a container at least 20 cm deep, fill with peat-free multipurpose compost and sow seed clusters 5 cm apart, 2 cm deep, thinning to one seedling per station for eight to ten plants in a 30 cm pot. Fresh compost carries the crop without extra feed. Keep the compost evenly moist, since pots that dry out give woody, ringed roots, and pull at golf-ball size. Sow a new pot every month from April to July for a steady supply.

Beetroot: common questions

When can I sow beetroot outside in the UK?

From mid March under cloches or fleece, and without protection from mid April to mid July. Use a bolt-resistant variety such as Boltardy for anything sown before mid April, because seedlings chilled early in life tend to flower instead of forming a root.

Why is my beetroot all leaf and no root?

Crowding is the usual cause: each seed cluster produces two to four seedlings, and unless they are thinned none has room to swell. Too much nitrogen, shade and dry soil have the same effect. Thin to 10 cm apart, or 5 cm for baby beets, as soon as the seedlings can be handled.

Can you eat beetroot leaves?

Yes. Young leaves and thinnings are good raw in salads and older leaves can be cooked like chard, which is the same species. Take only a few outer leaves from each plant, because stripping the tops slows the root.
