Before growing cauliflower, it is very important that the soil and land is prepared optimally. In order make the soil fertile and good for cauliflower cultivation it is highly recommended to mix manure or compost to a depth of 15 to 20cm. After preparing the soil with compost, it can be treated for root knot nematode for better cauliflower productivity and after 2 to 3 weeks, plantation of cauliflower can start. The soil is prepared by adding manure or compost to the soil at ratio of 10kg/m2, which is followed by ploughing or digging in order to break the soil clots. After that the soil bed is sterilized by formalin treatment and it is ready for transfer of the transplants after 15 to 20 days. Once the soil is treated with formalin it should be kept covered by polythene for a week and after that the beds are dug again and left open for 5 - 6 days. This treatment minimises any harmful effect by formalin to the seeds. Formalin treatment prevent fungal attack.
It is very rare that cauliflower seeds are sown directly in the field. Instead cauliflower is grown in controlled condition in green house and the transplants are transferred to field after few weeks. Once transplants are ready, furrows are formed where they are grown.
