This crop is quite cold resistant, making it well adapted to cool season production. As with most cole crops, a cold period is necessary for flowering. The minimum and maximum growing temperatures for cauliflower are 0 and 30 °C, with the optimum growing temperature for this crop between 15 and 22 °C. Cauliflower is grown on many different types of soil, but does best in a rich, well-drained soil with a high moisture-holding capacity. High humus content in the soil will provide better aeration and water penetration. Cauliflower grows best on a neutral or slightly acid soil (pH 6,0 to 6,5). Special attention must be paid to sufficient application of Boron, since a deficiency in this element will result in a hollow stem.
