Beetroot Detroit was first introduced in 1892 by the D.M. Ferry Seed Company, in Michigan, USA. It was bred from a variety described as an early maturing European Blood Turnip (Long Red).
This globe-rooted beetroot with dark red roots remains a firm favourite with today's commercial growers and home gardeners alike. Since its introduction a number of distinct cultivars and hybrids have been bred from the original Detroit stock. These modern lines are tolerant of Cercospora leaf spot and downy mildew and are resistant to bolting. Many contain the Detroit name.
It is a classic, main-crop globe beetroot which produces excellent quality, smooth skinned globe beets with strong skin and ox-blood flesh colour.
This high yielding variety has good internal colouring and excellent taste. It is suited to both early and main crops and can be grown in containers all year round. It is resistant to downy mildew and does well in all kinds of soils. It is recommended as a good cultivar to use for succession sowings.
The young luxuriant red-veined leaves can be eaten like spinach and the dark red, delicious tasting roots are ideal for baking, pickling, or grating raw into salads. Alternate roots can be thinned for use as baby beet and the rest allowed to grow on to maturity.
How to grow Beetroot:
Beetroot are remarkably easy to grow and can be grown across a wide range of climates. It prefers moist, sunny conditions with not excessive heat. It is sown as a warm season crop in most regions, but performs best during the cooler, drier months in tropical zones where it may prefer some shade in summer conditions
Beetroot seeds are clustered together with each cork-like fruit containing two or three seeds. Once germinated, they require thinning out early to avoid root disturbance. (Some varieties have been bred to only produce one seed and are called 'Monogerm' seeds).
Position:
Beetroot prefer to be grown in light, sandy soil in a sunny position, but can tolerate pretty much any sort of soil and some shade will be tolerated, a pH of 6.0-7.0 is fine but if you know your soil is too acid dig in some lime.
Dig over the site with a spade (preferably in the autumn prior to sowing). Remove perennial weeds and large stones as these can cause the roots to become mis-shapen
Level roughly and then work over the area with a rake to leave a fine finish. If you can, two or three weeks before sowing, spread a general granular fertiliser across the site and rake into the soil. Do not add manure to the soil as this will cause the roots to develop incorrectly.
When to sow Beetroot: Late spring to autumn.
Beetroots can be grown from early spring onwards if grown indoors or undercover.
Seeds can be planted directly into the ground after the threat of frost has passed. Beetroots are best planted at soil temperatures between 7°C and 25°C. The best quality beetroots are grown at temperatures of 10 to 18°C (50 to 65°F).The crops will tolerate light frost.
How to sow Beetroot:
The seeds require plenty of moisture to germinate. Soaking them in warm water for an hour or two prior to planting is a great way to speed up germination. Expected germination time 10 to 14 days.
Prevent a glut when planting beetroot by sowing your seed in stages, a small batch at a time every couple of weeks will give a continuous harvest.
Sowing Indoors: From February
Sow 2 or 3 seeds per pot, at a depth of 25mm (1in). When the seedlings emerge there may be more than one from each seed cluster. When they are about 5cm (2in) tall, carefully separate these into individual plants prior to planting out (only transplant the strongest seedlings). This will avoid seedlings competing with one another and prevent a distorted, misshapen harvest.
Successful transplanting can be carried out as soon as plants have formed their first true leaves. Unlike other root crops, beetroot seedlings transplant reasonably well providing they are not too large and are kept moist when transplanting.
Sowing Direct: From May
It is best to sow beetroot seeds directly into the ground when the temperature of the soil has warmed to about 7°C (44°F). Sow thinly in prepared seed beds. Where plants are sown direct it is important to thin the multiple seedlings back to one plant. If carefully removed, the thinnings can be transplanted to form additional rows.
The spacing is quite important. If you wish to grow small, pickling size beets, they need to be sown quite close together, about 5cm (2in) apart, in rows 15cm (6in) apart. If you wish to grow standard size beetroots, then sow about 10cm (4in) apart, in rows that are at least 30cm (12in) apart.
Cover lightly with 25mm (1in) of fine soil. Firm gently, water well and keep moist.
Seedlings appear in 7 to 21 days. When large enough thin to at least 10cm (4in) apart.
To Grow in Containers: All Year Round
Containers are ideal for round beetroot varieties, (not long cylindrical ones), choose containers that are 20cm (8in) in diameter and at least 20cm (8in) deep. Fill loosely with multi-purpose compost leaving the compost just shy of the top. Tap the pot gently to settle, and firm with your finger tips aiming to leave a 4cm (1.5in) gap between the surface of the compost and the top of the pot.
Cultivation:
Keep the rows weed free and the seedlings well watered. Once the roots have developed and they start to swell, beetroots need to be watered moderately. Beetroot has shallow roots and it is important to keep the plants moist. If they experience long dry periods, the beetroot will become hairy and fibrous. Intermittent or inadequate watering can result in stress cracks and breakdown of roots. Don't overwater as this only encourages leaf growth and not bulb growth.
During cool weather, the plants can be watered once a week. During very hot weather, less water can be given two to three times a week instead of a lot of water once a week.
Companion Planting:
Good Companions - Onions, Silverbeet, Kohlrabi, Lettuce, Cabbage, Dwarf Beans. Aromatic Herbs, Celery, Chamomile, Spinach, Chard.
Bad Companions - tall beans, runner beans.
Harvesting:
Beetroot is ready to be picked when the roots are between the size of a golf ball and a tennis ball – this is usually 12 to 16 weeks after sowing. The smaller the root the better the quality.
Pull from all along the row and not just in one place, as this thins out the rows, allowing more space for the other beetroot to grow. To harvest, gently hold the tops and lift while levering under the root with a hand fork. Remove the tops by twisting them off with your hands to prevent the plants bleeding their juice – don’t throw these away, they have bags of taste and can be cooked and eaten like spinach. Store roots in dry sand, soil, or peat for winter use.
Culinary Uses:
Before cooking beets, cut off the tops within a couple of inches of the top. This helps lock in the nutrients during cooking. When the tops are attached to any root vegetable, they leech the nutrients from the root. They should be cooked whole and then peeled; otherwise, they bleed all their colour and nutrients into the water.
The deep-red roots are eaten Boiled, steamed or roasted as a vegetable (if roasted, cover with lemon juice to stop browning). They can be eaten cold as a salad after cooking and adding oil and vinegar, or raw and shredded.
A large proportion of commercial production is processed into boiled and sterilised beets or into pickles. In Eastern Europe beet soup, such as cold borscht, is a popular dish. Beetroot leaves are lovely in a salad or cooked. Use as you would spinach.
Beetroot can easily be stored for later use, and the most common method is by pickling them in vinegar.
