Snowball Y Improved cauliflowers likes well-draining, very fertile soil with lots of compost and organic matter. They are not very heat or cold tolerant and will need more attention. Water consistently and thoroughly to keep the soil lightly moist, not soggy. Check the top 1-2 inches of soil and do not let it dry out completely. Make sure to water at the base and not from above to prevent rot or disease.
Adding a layer of mulch helps in maintaining a moist soil and preventing weed growth. Compost should be used above fertilizer but 20-20-20 or 20-10-10 fertilizer is also good for cauliflower.
