Washington State, known for its fertile soil and diverse agricultural landscape, has gained recognition for a wide range of crops. Among these, cauliflower stands as a versatile and nutritious vegetable that thrives in the state's favorable growing conditions. In this blog, we'll delve into the world of cauliflower, exploring its cultivation, unique attributes, as well as its nutritional value and why it's a favored choice in low-carb diets.
Cauliflower growing requirements
Cauliflower thrives in cool weather when daytime temperatures are between 65-80 degrees Fahrenheit. It tends to be more sensitive to heat than its cousin broccoli. It does best when planted mid-summer for a fall harvest.
Brassicas, in general, grow best in fertile, well-drained soils. The pH should be between 6-7 to discourage clubroot disease and maximize nutrient uptake. An 8-16-16 fertilizer will help cauliflower thrive. Space your plants 24” apart with 30” between rows. Gathering and tying the leaves when the head starts to form helps ensure the crop will be white and tender. One to 1½ inches of water a week will suffice. Harvest your crop before the leaves begin to turn yellow and before the buds start to separate. The plant will continue to produce offshoots if leaves are still present.
The biggest pest problem with cauliflower, and all brassicas, are those pesky cabbage worms. You can read more about them in our broccoli blog. Other challenging pests include cabbage root maggot, aphids, flea beetles, blackleg black rot, clubroot, and yellows.
