Cauliflowers do best in very fertile soil, and digging in a bucketful of well-rotted manure or organic matter before planting, and raking in a high potassium general fertiliser, such as Vitax Q4, at a rate of three handfuls per square metre/yard, will help growth. Firm the soil by treading before planting
Space summer and autumn cropping types 60cm (2ft) apart and winter cultivars around 75cm (2.5ft) apart; spacing of 30-45cm (12-18in) apart, provides mini, ‘one person’ curds.
Water well in dry weather, watering every 10 days, and apply sufficient water to thoroughly wet the root zone. Once the plants are growing well, add 30g (1oz) per square metre of high nitrogen fertiliser such as sulphate of ammonia to boost growth and curd formation
