|In the 1st Century Pliny describes a plant that is very cauliflower-like. He called it Cyma and said that it was the most pleasant tasting of the cabbage varieties.

As the ‘head’ or ‘curd’ develops the outer leaves can me folded over it to avoid sun blanching and causing discolouration.
Harvest while the heads are firm and tight.
Storing harvested Cauliflower: Cauliflower can be dehydrated or blanched and frozen for excellent flavour. Does not hold it’s flavour well when canned.

|Downy Mildew – pale spots or blotches on leaves. Possible mildew on underside of the leaves. Space plants to allow for good air circulation. Weed.
Potassium Deficiency – scorching or burning on leaf margins. Poor quality hearts.
Magnesium Deficiency – yellowing between veins on older leaves. Add fertiliser.
Molybdenum Deficiency – leaves thin and strap-like, poor growth. Add fertiliser.
Boron Deficiency – hollow stems. Head may become brown or lumpy. Add fertiliser
Smaller heads than expected – cold weather
Bolting/Running to seed prematurely – cold weather followed by hot weather. Root exposure
Club Root – plants stunted, deformed roots. Add lime to soil. Destroy diseased plants. Ensure good drainage. Crop rotation.
Discoloured Head – yellowed head on cauliflower. Sunburn. Fold leaves over head to shade.
Head is Soft/Breaking up – Over-mature. Pick sooner.
|White Butterfly/Diamond Backed Moth – holes in vegetation in late spring, summer, autumn. Protect young plants with insect mesh
Aphids – small insects clustered in developing heart or crown. Keep plants well watered in dry weather
Slugs and snails – holes in leaves or stems in winter. Digital removal (pick the bugs off), coffee grounds, ground egg shells said to be a deterrent.
Whitefly – underside of leaves covered with tiny white insects that will fly when disturbed.
Cover your garden with insect netting to avoid having your plants become a meal for caterpillars and bugs. There are a variety of sprays and solutions (both organic and non-organic) such as Derris Dust or Quash available to combat such pests.
