How to grow cauliflower

Cauliflower can be quite difficult to grow. It requires deep rich soil, and at all times during the growing period it must not be checked in growth in any way.
Tiny button like heads will be produced if this is allowed to happen, and a lot of completely wasted time and effort on your part. The correct soil preparation, proper planting and the correct watering are essential, along with the best choice of variety.
There are types which will produce nice firm white heads at every time of the year. But in Scotland, avoid varieties such as Roscoff, which only succeed in areas in the far south such as Devon, and Cornwall. Grow a variety such as Mammoth which would really impress your fellow plot holders.
Or why not try the modern varieties like Clapton F1, a clubroot resistant variety, available from "Dobies of Devon", a direct link can be found by clicking here.
The soil should be dug over during the previous summer or autumn, allowing it to become well consolidated, and firm before planting in the early spring. Dig in plenty of well rottted manure or use a growmore type compost as a top dressing in spring. Choose a sunny position to plant out until harvesting.
Try and avoid an area which would be susceptable to frost for winter types. In the autumn as stated dig in some well rotted manure, and also use use some garden lime in the back end to the manufacturer's recommendations.
Also apply a top dress of fertiliser in the spring time when putting in the young plants.
Cabbage root fly is a huge problem to the gardener and the use of felt or other types of protective collars placed around the base of the stem once planted protects the young plants very well.
