Cauliflower: A Beginner’s Guide to Growing Cauliflowers Indoors

A cauliflower is not a common choice of vegetable to plant for many home gardeners. A lot of people may be intimidated by the idea, thinking that it is a large plant. Truth is, it has shallow roots, which makes it easy to grow even in containers. Unknown to many, growing cauliflower is an easy process, similar to growing tomatoes and other common indoor plants.

A brassica similar to broccoli, collards, kale, and cabbage, cauliflower is a cool-season crop, which is why there is no problem even if you grow it indoors and in a place that does not receive full sun. Its cultivation started in as early as 600 BC in Turkey. In Europe, cultivation first started in the 16th century and in the United States, in the 20th century. The height and width of the flower can range from eight to 30 inches. Since you will be growing them indoors, choose a cultivar that is smaller. It has coarse and large leaves, which form a rosette. There are leaves surrounding the stalks, and in the middle, there is a white head that looks like a small tree. Its head has an average width of six inches and weight of two to three pounds. The most common color of the head is white, although there are also some that are yellow, purple, or orange, among others.

There are different varieties of cauliflower, each with their respective physical characteristics. One of the most popular is White Cloud, which is obviously a white variety of cauliflower.

It has 25 times more beta carotene than what you can find in white cauliflower, which gives its head a distinct orange color. Purple of Sicily, on the other hand, has a bright purple color, superb flavor, and plenty of nutrients.

Planting and Growing Conditions

The first thing that you have to do is to look for high-quality, disease-free seeds, which will depend on the specific variety that you would like to propagate. Start planting just before winter or at least six weeks before you need the vegetable.

After preparing your seeds, the next thing that requires your attention is the right choice of a container. On average, the pot should be at least 12 to 18 inches wide and 8 to 12 inches deep. For a standard container, it is advisable that you grow only one in each of them. Any material will be acceptable, as long as there are drainage holes at the bottom.

Your choice of soil will be another critical factor that will influence the success of growing a cauliflower. The potting mix should be lightweight, loose, and well-draining. It will be best to add coconut bark, compost, and perlite, among other components that could enrich the nutrients in the soil.

Fill the pot with your potting mix, but be sure to not over-fill it up until the rim. It will be good to leave a space of at least half an inch. Using your finger, poke the soil to create holes. Fill it with your seeds. Make sure that there is more than enough space to accommodate the growth of the plant.
