Beetroot seed buying and growing guide
Beetroot is a productive root vegetable grown for its colourful swollen roots, tender young leaves and edible stems. Varieties differ in root colour, shape, maturity, foliage and suitability for roasting, boiling, pickling, bunching, baby beetroot or baby leaf production.
Seedmart supplies beetroot seeds for home gardeners, market gardeners and commercial vegetable growers throughout Australia. Choose from traditional round red beetroot, golden varieties, cylindrical roots and specialty beetroot with deeply coloured foliage.
The best beetroot seed will depend on the root shape, colour, growing time, harvest size and culinary or commercial use you require.
Beetroot can produce dependable harvests when grown in loose soil with consistent moisture and sufficient plant spacing.
Harvest the developed roots as well as tender young leaves for salads, mixed greens and cooked dishes.
Grow beetroot in raised beds, troughs and sufficiently deep containers with good drainage.
Choose from deep red, golden, round, cylindrical and coloured-leaf beetroot varieties.
Small sowings made at regular intervals can provide a continued supply of roots and young leaves.
Select smaller packs for household gardens or larger quantities for repeated and commercial production.
Some varieties are selected for uniform round roots, while others are grown for early harvests, cylindrical shape, golden colour or distinctive edible foliage.
| Growing Goal | Recommended Varieties | Why Choose Them? |
|---|---|---|
| Classic round beetroot | Red Detroit and Ruby Queen | Produce familiar rounded red roots suited to general cooking, pickling and fresh-market sales. |
| Golden beetroot | Golden Detroit | Produces golden-yellow roots that provide strong colour contrast and less red staining during preparation. |
| Uniform slicing | Cylindra | Forms elongated roots that produce more consistent slices along much of their length. |
| Early production | Early Wonder | Selected for relatively early root development and productive edible tops. |
| Baby beetroot | Red Detroit, Ruby Queen and Early Wonder | May be harvested while the roots are still small and tender. |
| Colourful baby leaves | Bull’s Blood | Develops dark red foliage suited to baby leaf production and colourful edible plantings. |
| Pickling and preserving | Red Detroit, Ruby Queen and Cylindra | Reliable root colour and shape for slicing, cooking and preserving. |
| Market garden production | Red Detroit, Ruby Queen, Cylindra and Early Wonder | Recognisable varieties suited to scheduled sowings, bunching and mature root production. |
Red Detroit produces smooth, rounded roots with deep red flesh. It is a versatile traditional beetroot for home gardens and larger plantings.
Ruby Queen develops rounded red roots selected for smooth appearance, good internal colour and dependable garden performance.
Golden Detroit produces golden-yellow roots and provides an attractive alternative to conventional red beetroot.
Cylindra forms long, narrow roots rather than conventional round beetroot. Its shape is useful where evenly sized slices are required.
Early Wonder is valued for relatively quick root development and useful leafy tops that may also be harvested young.
Bull’s Blood develops dark burgundy-red leaves and stems, making it particularly useful for baby leaf and specialty vegetable production.
Beetroot generally grows best during cool to mild weather, although the most suitable sowing period depends on the local climate. It requires loose, free-draining soil, good sunlight and steady moisture to produce evenly shaped roots.
Grow beetroot in full sun where possible. Light shade may be tolerated, but insufficient light can reduce root development.
Break up compacted soil and remove stones or hard clods that could restrict or distort the developing roots.
Water consistently enough to support steady growth without leaving the soil saturated or poorly aerated.
Most beetroot seed clusters can produce several seedlings. Thin them early so the remaining roots have enough space to develop.
Planting time varies across Australia’s tropical, subtropical, temperate, cool and arid regions. Beetroot generally performs best during mild conditions rather than periods of prolonged extreme heat.
| Climate Zone | General Sowing Period | Growing Notes |
|---|---|---|
| Cool | September to February | Sow after severe frost risk has eased and allow late crops sufficient time to mature before winter. |
| Temperate | August to April | Spring and autumn are generally reliable, with summer sowing possible where extreme heat can be avoided. |
| Subtropical | March to September | Concentrate planting through the cooler and less humid part of the year. |
| Tropical | April to August | Grow primarily during the cooler dry season with good drainage and reliable irrigation. |
| Arid | March to May and August to October | Sow during mild weather and maintain consistent moisture during establishment and root development. |
These sowing periods are general guides. Local frost dates, elevation, rainfall, seasonal temperatures and extreme weather should also be considered.
Location-specific planting times should be adjusted according to local temperatures, frost risk and seasonal conditions.
| Location | General Planting Guide | Key Considerations |
|---|---|---|
| Brisbane and coastal Queensland | March to September | Plant through the cooler months and avoid the hottest, wettest part of summer where possible. |
| Sydney and coastal New South Wales | February to November | Autumn and spring are generally reliable, with winter planting possible in mild coastal areas. |
| Inland New South Wales | March to May and August to October | Avoid severe frost periods and prolonged midsummer heat. |
| Melbourne and Victoria | August to April | Plant through spring and autumn, with summer sowings possible where moisture can be maintained. |
| Adelaide and South Australia | February to November | Avoid the hottest part of summer and provide reliable irrigation during dry conditions. |
| Perth and south-west Western Australia | March to November | Autumn through spring generally provides the most suitable conditions. |
| Tasmania | September to February | Plant after severe frost risk has reduced and use the warmer growing months. |
| Darwin and tropical northern Australia | April to July | Grow during the cooler dry season and avoid hot, highly humid wet-season conditions. |
Beetroot is generally best direct-sown into the bed or container where the roots will develop. Direct sowing reduces disturbance and allows the young taproots to grow without interruption.
Plant beetroot seed clusters approximately 1–2 cm deep. Use the shallower end of this range in heavy or cool soil and slightly deeper planting where the soil is light and the surface dries quickly.
Seed planted too deeply may emerge slowly or unevenly. Seed left on the surface can dry out, move during watering or be disturbed by birds and other animals.
Use a shallow sowing depth and improve the surface structure before planting.
Slightly deeper planting can help prevent the seed from drying too quickly.
Plant one natural beetroot seed cluster at each sowing position. Because a cluster can contain several seeds, more than one seedling may emerge.
Do not assume that every emerging seedling represents a separate seed accidentally planted in the same place. Multiple emergence is normal for traditional multigerm beetroot varieties.
Thin the seedlings according to the intended harvest:
| Harvest Goal | Approximate Plant Spacing | General Result |
|---|---|---|
| Baby leaf | Closely sown | Dense planting for harvesting tender young leaves before root development becomes important. |
| Baby beetroot | Approximately 3–5 cm | Produces smaller roots suited to early harvesting and specialty bunches. |
| Medium roots | Approximately 7–10 cm | Provides room for useful round roots without requiring maximum mature size. |
| Large mature roots | Approximately 10–15 cm | Allows greater space for full-sized roots, depending on the variety. |
| Cylindra beetroot | Approximately 8–12 cm | Provides space for long roots to expand without excessive competition. |
Beetroot seeds commonly germinate within approximately 7–14 days under suitable conditions. Emergence may occur sooner in warm, consistently moist soil or take longer when the soil is cold, dry, compacted or excessively wet.
Mild soil temperatures generally support faster and more uniform germination than very cold or excessively hot conditions.
The seedbed should remain evenly moist without becoming saturated or waterlogged.
Seed planted approximately 1–2 cm deep is less likely to dry out while still being shallow enough to emerge readily.
Loose, fine soil allows seedlings to emerge more easily than hard, compacted or crusted soil.
No. Beetroot seeds do not require light to germinate and should be covered lightly with soil. Germination depends primarily on moisture, temperature and oxygen within the seedbed.
The emerging seedlings require light once they reach the surface. After emergence, grow beetroot in full sun or the brightest suitable position available.
Soaking beetroot seed is optional rather than essential. The clusters can be sown dry into a prepared, consistently moist seedbed.
A short soak may accelerate water absorption through the corky outer cluster, but soaked seeds must be planted promptly and handled carefully.
Dry sowing is straightforward and reduces the risk of soaked seed being damaged before planting.
A short soak may be used where the seedbed is ready and planting will occur immediately.
Beetroot seedlings can be transplanted carefully, but direct sowing is generally preferred because root disturbance may result in misshapen or forked roots.
Transplanting is most successful while seedlings are small and before the taproots become long or tangled. Lift them with as much surrounding soil as possible and replant at the same depth.
Yes. Beetroot grows well in pots, troughs and raised containers where sufficient depth, drainage and sunlight are provided.
Choose a container at least approximately 20–30 cm deep for round beetroot. Cylindrical varieties may require a deeper root zone.
Use a pot or trough large enough to support the number and mature size of the roots being grown.
Container-grown beetroot can dry out faster than plants growing in open soil.
Many beetroot varieties produce harvestable roots in approximately 50–80 days. Baby beetroot and young leaves can be harvested earlier, while larger mature roots may require more time.
| Harvest Stage | Typical Period | General Characteristics |
|---|---|---|
| Baby leaves | Approximately 25–35 days | Tender young foliage harvested before substantial root development. |
| Baby beetroot | Approximately 40–55 days | Small, tender roots lifted before reaching mature size. |
| Medium mature roots | Approximately 50–70 days | Typical household and fresh-market harvest size for many varieties. |
| Large or slower varieties | Approximately 70–90 days | Longer growing period for full-sized roots or varieties with later maturity. |
Growing time varies with variety, soil temperature, sunlight, spacing, fertility, moisture and preferred root size.
Beetroot can be harvested whenever the roots have reached a useful size. Young roots are usually tender, while roots left to become excessively large may develop a coarser texture.
The upper shoulders of the roots often become visible above the soil. Use this exposed portion to estimate size without digging up the entire plant.
Lift small roots when they reach approximately 3–5 cm across for tender texture and quicker crop turnover.
Harvest round varieties when they reach approximately golf-ball to tennis-ball size, depending on the intended use.
Check both the exposed shoulder and the expected root length before harvesting cylindrical varieties.
Harvest with fresh leafy tops attached while the foliage remains clean, healthy and attractive.
Beetroot is generally ready when the exposed shoulder reaches the preferred diameter and the root feels firm. The foliage should remain reasonably healthy, although leaf size alone does not confirm root maturity.
Signs that beetroot is ready include:
Beetroot can remain in the soil for a limited period after reaching harvestable size, especially during cool, mild conditions. However, leaving mature roots too long may result in oversized, woody or cracked beetroot.
Harvest promptly where:
Beetroot may be grown for mature roots, baby roots, tender leaves or a combination of roots and foliage.
Root production requires loose soil, adequate spacing and sufficient healthy foliage.
Young beetroot leaves may be harvested for baby leaf mixes or grown into larger cooking greens.
Beetroot performs best in full sun but can tolerate light partial shade. Plants grown with insufficient light may develop abundant leaves without producing well-sized roots.
In hot climates, brief afternoon protection may help reduce heat stress. However, prolonged deep shade is unsuitable for reliable root production.
Beetroot can be grown across a broad seasonal range, but local temperature is more important than the calendar month.
| Season | Suitability | Management |
|---|---|---|
| Summer | Possible in cool and mild regions, but difficult during prolonged extreme heat. | Maintain moisture, use suitable planting windows and consider light afternoon protection. |
| Autumn | Often an excellent planting period across temperate, subtropical and arid regions. | Allow enough growing time before severe winter frost where relevant. |
| Winter | Suitable in mild and frost-free regions, with slower growth in cold areas. | Avoid saturated soil and protect young plants from severe frost. |
| Spring | A reliable planting period in temperate and cool climates. | Maintain moisture as temperatures rise and harvest before prolonged heat. |
Beetroot can be included in mixed vegetable beds with crops that have compatible spacing, watering and seasonal requirements.
Potential neighbouring crops include:
Companion planting should not replace appropriate spacing, crop rotation, pest management or soil preparation. Avoid crowding beetroot with vigorous crops that shade the foliage or compete heavily for water.
Cold soil, surface drying, deep sowing, waterlogging or hard soil crusting can reduce emergence.
Overcrowding, compacted soil, insufficient light, drought stress or excessive leaf harvesting can restrict root growth.
Roots may become coarse when left too long, exposed to heat or allowed to grow unevenly.
Cracking can occur when dry soil is followed by sudden heavy watering or substantial rainfall.
Excessive nitrogen, insufficient light or overcrowding may promote leaf growth at the expense of roots.
Stones, hard soil, transplant damage and compaction can cause forked or misshapen beetroot.
Smaller seed quantities are suitable for household gardens, containers and growers trialling different colours and root shapes.
Bulk beetroot seed can be more economical for growers producing repeated crops, baby beetroot, bunches, mature roots or baby leaves.
Commercial beetroot production requires varieties suited to the intended harvest size, root shape, planting density, processing method and target market.
Consistent root size and shape simplify bunching, packing, slicing, processing and market presentation.
Traditional multigerm seed clusters can produce several seedlings, making establishment and thinning management important.
Determine whether the crop will be sold as baby beetroot, mature loose roots, fresh bunches or processed slices.
Select familiar red varieties for broad demand and golden, cylindrical or coloured-leaf types for specialist markets.
Yes. Beetroot is generally straightforward to grow when it is direct-sown into loose soil, thinned correctly and watered consistently. Compacted soil and overcrowding are among the most common causes of poor roots.
Direct sow the seed clusters approximately 1–2 cm deep into loose, free-draining soil. Keep the seedbed evenly moist and thin multiple seedlings after emergence to provide room for root development.
Beetroot generally grows best during cool to mild conditions. Temperate growers can often sow from late winter through autumn, while tropical and subtropical growers usually concentrate on the cooler dry-season months.
Plant beetroot seed clusters approximately 1–2 cm deep. Sow slightly shallower in heavy soil and avoid burying the seed deeply.
Beetroot commonly germinates in approximately 7–14 days. Cold soil, deep planting, surface drying, compaction and waterlogging can delay emergence.
No. Cover the seeds lightly with soil. They require suitable moisture, temperature and oxygen rather than exposure to light during germination.
Soaking is optional. Beetroot can be planted dry into moist soil. A short soak may accelerate water uptake, but soaked seed should be planted promptly.
Most traditional beetroot seed is supplied as natural multigerm clusters. Each cluster may contain several botanical seeds and can therefore produce more than one seedling.
Usually, yes. Thin crowded seedlings so the remaining plants have enough room to develop useful roots. Spacing will depend on whether baby or mature beetroot is required.
They can be transplanted carefully while young, but direct sowing is generally preferred. Root disturbance during transplanting can result in irregularly shaped beetroot.
Yes. Use a container with good drainage and at least approximately 20–30 cm of soil depth. Cylindrical beetroot may require a deeper container.
Beetroot can tolerate light partial shade, but full sun generally produces better root development. Deep shade may result in large leaves and undersized roots.
Many varieties produce mature roots in approximately 50–80 days. Baby roots and leaves can be harvested earlier, while large roots may require longer.
Beetroot is ready when the exposed shoulder has reached the preferred diameter and the root feels firm. Harvest a test root before lifting the complete planting.
Beetroot may be harvested at baby size or allowed to mature. Round roots are commonly harvested between approximately golf-ball and tennis-ball size, depending on the variety and intended use.
Beetroot can remain in the ground for a short period after reaching harvest size during mild conditions. Leaving roots too long can result in woody texture, cracking or excessive size.
Possible causes include cold or dry soil, excessive watering, poor drainage, deep planting, compacted surface soil or old seed. Maintain steady moisture without saturating the bed.
Small roots may result from overcrowding, compacted soil, insufficient sunlight, drought stress, excessive leaf harvesting or harvesting before maturity.
Woody texture may develop when roots become oversized, experience prolonged heat or drought, or grow unevenly because of irregular watering.
Yes. Tender young beetroot leaves may be used in salads and mixed greens, while larger leaves can be cooked similarly to silverbeet.
Yes. Sow beetroot more densely and harvest the foliage while young. Bull’s Blood is particularly valued for its dark-coloured leaves.
They can share a bed where adequate spacing, sunlight and soil depth are available. Both are root crops, so avoid planting them so densely that they compete heavily below ground.
Yes. Beetroot and onions can be grown in the same general bed where each crop receives sufficient spacing, light, moisture and nutrients.
Seed may be saved from suitable open-pollinated varieties. Beetroot is generally biennial and flowers in its second growing season. It can cross-pollinate with other beet and silverbeet varieties, so isolation is required.
