Description
‘Snowball’ cauliflower is a superb American heirloom variety, thought to be selected from the German ‘Erfurt’ variety. This early cauliflower forms small, pure white heads surrounded by beautiful wavy green leaves. A delicate, fine-textured variety that is best eaten fresh. Sow under cover in September/October, plant out in March and harvest from June to July.
Cauliflower (Brassica oleracea botrytris) is a popular vegetable belonging to the large Brassicaceae family (ex-Cole family). This biennial plant is grown as an annual for its edible flower head (meristem). It is thought to be native to the Island of Cyprus. The most common varieties display creamy white heads (or “curd”). However, more recently, different coloured cultivars have been introduced with orange, purple or green heads. Cauliflower has a mild, nutty taste. It is delicious eaten raw with dips, blended in velouté soups, or lightly steamed and added to gratins or quiches. It also goes very well with curry. From a nutritional point of view, it is very healthy: it is low in calories but very rich in vitamins, fibre and minerals. The orange varieties contain beta-carotene.
Cauliflower can be a rather tricky vegetable to grow. It requires deep, rich soil, and regular watering. It enjoys plenty of sun but not too much heat as this tends to make the florets taste more bitter. Better results are generally achieved in cooler, rainier climates. There are many varieties to choose from. By respecting the correct growing period, it is possible to harvest cauliflowers nearly all year round.
Harvesting: To harvest Cauliflower, simply cut off the central head with a sharp knife when it feels suitably compact and heavy.
Storage: Cauliflower does not keep very well. It is best to eat it quickly after harvesting, although it will keep for a few days in the refrigerator. It is also possible to freeze the florets after having blanched them in boiling salty water for a few minutes.
Good to know: For the past few years, swede midges (Contarinia nasturtii) have been causing considerable damage to brassica plants. We recommend protecting your crops with insect netting from mid-May to mid-July.
Even if the vegetable garden is first and foremost a place for growing great quality veg, it’s always a good idea to leave a bit of room for flowers. Growing flowers alongside your vegetable plants will make your general gardening experience more enjoyable and is a great way to attract pollinators and repel garden pests! Flowers such as gaillardia, marigolds, zinnias, cosmos or nasturtiums can be sown in and around the rows of vegetables. Herbs such as dill can be very useful also. Bear in mind that some companion plants self-seed easily and can be a bit invasive (borage, chives, lemon balm etc.)

Planting and care
Sowing: The germination temperature for Erfurt Snowball Cauliflower is around 12°C and takes about 14 days.
This cauliflower is sown under shelter in September/October and planted in March for a harvest from June to July.
You can either sow the seeds directly in the ground or prepare seedlings that will later be planted in their final position in the garden.
Preparing seedlings: From late autumn to the end of spring, sow cauliflower seeds at a depth of 1 cm in a tray filled with good seed compost, either at home or in a heated shelter. Cover lightly with compost or vermiculite. Cover with the transparent lid of the tray or plastic film until germination. Don't forget to keep the substrate moist but not waterlogged!
When the young plants appear strong enough to handle, transplant them into pots. For seeds sown under heated shelter, gradually acclimatize them to cooler temperatures before transplanting them into the garden, when there is no longer any risk of frost.
Direct sowing: In well-amended and finely worked soil, create furrows about 1 cm deep, spaced 60 cm apart. Sow the seeds and cover them with a thin layer of fine soil. Once the seedlings are well developed, thin them out, keeping only one plant every 60 cm.
Cultivation
Cauliflower is a demanding vegetable that requires well-fertilized soil rich in nitrogen and potassium. It is recommended to apply a generous amount of mature compost (about 3/4 kg per m2) in autumn, by raking it in to a depth of 5 cm, after loosening the soil as you would for any vegetable crop. It is not very tolerant of soil pH and should be between 5.6 and 6.5. In acidic soil, it is necessary to gradually increase the pH by adding calcium in the form of Dolomite or Lime.
Cauliflower, like all cabbages, is quite susceptible to diseases such as Clubroot and pests (Cabbage White Butterfly, Cabbage Fly, Flea Beetle, Gall Midge...), so it is very important, for this crop, to practice crop rotation.
It is beneficial to associate cauliflower with many vegetables such as tomatoes, lettuce... But avoid planting it next to other Brassicas as well as zucchini, fennel, lamb's lettuce, leeks, and strawberries.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
