Brassica oleracea botrytis cauliflora Cultivation | Propagation | General Uses Cultivation Notes: Succeeds in full sun in a well-drained fertile soil with plenty of lime[37, 200]. Prefers a heavy soil[16]. Requires a warm sunny position[16]. Prefers a pH in the range 6 to 7[200]. Tolerates a pH in the range 4.3 to 8.3. Succeeds in maritime gardens[200]. Winter cauliflowers are hardy to about -6°c, but the curds are more sensitive, suffering damage at about -2°c[200]. Cauliflowers are often grown for their edible immature flower heads (or curd), there are many named varieties that can provide a year round supply. Some cultivars are annual, they need to produce a certain number of leaves before curd development will be initiated. The optimum temperature for this is around 17°c, but at temperatures above 20°c the curds will either be of poor quality or not be produced at all[200]. Biennial and intermediate types need exposure to temperatures below 10°c before they will produce curds and once again, this will not happen unless the plant has reached a certain size[200]. Grows well with celery and other aromatic plants since these seem to deter insect predations[18, 20, 201]. Grows badly with beet, tomatoes, onions and strawberries[20, 201].
