Preparing the Soil:

To prepare soil for cauliflower, you should keep it neutral but a little bit acidic with a pH of 0.6 to 7.0. To measure the pH of soil you should test it. In case of low or high pH value, you can adjust it with lime or sulfur accordingly.

The soil is only called prepared when it have proper fertilizer. For fertilizers, you can either use chemical fertilizer or organic fertilizer. I personally use organic fertilizer in my garden. Other than that, the soil should be loose enough to prevent waterlogging and provide proper draining. For proper draining, you can also use a little bit of sand.

Choosing Right Variety:

After preparing the soil, now you have to choose the variety you want to grow. There are different types of variety to choose from; each one needs a unique temperature and climate. Some of the common varieties are given below.

Snowball: It is one of the compact types and varieties of cauliflower that has white heads, which are also suitable and preferred for most climates.

Cheddar: It is orange in color and has beta-carotene.

Graffiti: This variety of cauliflower is very high in antioxidants.

After deciding the variety of your cauliflower, you need to purchase it from a reputable source or supplier that has a high rate of germination.

Planting Techniques:

Now, it’s time to plant your cauliflower seeds. The caring way to plant your cauliflower is to make rows of 2 to 3 feet. Now start planting the seeds 1 to 2 inches deep, and also leave gap about 1 to 2 feet from one another.

The time of the plant normally depends upon the variety you choose. We chose the normal white cauliflower, which has two planting times or climates. If you live in cooler temperatures, then you should plant it in spring or late summer to harvest in fall. But if you live in a hot climate, then you should in early winter to harvest in early spring.

The caring of cauliflower also includes proper watering techniques for maintaining the soil moisture. You need to water the cauliflower with 1 to 2 inches of water per week in the absence of rainfall.

Sometimes, gardeners keep overwater or underwater cauliflower, which is very bad for the plant. If you underwater your cauliflower, then it affects its head growth, but if you overwater it, then it can rotten its root, which practically destroys the whole plant.

Fertilization:

Every plant needs fertilization for proper growth. Cauliflower needs fertilization in planting time and also in mid-season if needed. How would we know that it needs fertilizer? We mentioned some signs of fertilizer needs.

Leaves are turning yellow: when cauliflower leaves turn yellow, then it’s a sign of nitrogen deficiency. You should use a fertilizer with nitrogen.

Leaves turning purple or red: If the cauliflower leaves turn red or purple, then it’s a clear sign of phosphorus deficiency. You should use user fertilizer with phosphate.

Scorched Leaf Edges: If your garden cauliflower leaves start having scorched edges of its leaves then it indicates potassium deficiency. You could either use wood ash or also potassium sulfate.

Weeds and Pest Control:

Every vegetable plant attracts pests, and so does cauliflower so how to protect cauliflower plants? Controlling these pests has two methods: one is simple, just using a specific pest spray, and the other is an organic method. Personally, I have been using organic methods mostly.

Cabbage Worms:

One of the most common cauliflower pests is actually worms called ‘cabbage worms.’ You can also hand pick, or you just use Bacillus thuringiensis, which is a spray.

Aphids:

The easy method would be to spray with insecticidal soap, but the organic method would be to introduce ladybugs to cauliflower. The ladybugs eat these aphids.

Flea beetles:

For weed control, you should regularly remove weeds from your cauliflower to prevent competition for nutrients. Just like cauliflower, weeds also need water, nutrients, and sunlight for survival, for which they compete with cauliflower. So, make sure to remove all the possible weeds so the cauliflower gets the required resources to thrive and thats how to care for cauliflower in your garden

In the diseases, that cause by fungas. To prevent black rot from happening, you need to avoid watering the cauliflower on its head and keep proper air circulation.

Blanching Cauliflowers:

Blanching is a technique used in cauliflower to protect it from direct sunlight, and as a result, you get white, tender cauliflower heads. I follow this technique myself on my cauliflower and get pretty beautiful cauliflowers.

The technique is pretty simple: when the heads are 4 to 5 inches in diameter, then take its close surrounding leaves and tie them above its head with rubber or any type of clippers to shield it from direct sunlight. But make sure to keep some space between the head and leaves for the head to grow.

It usually takes 5 to 6 days in cold weather, while in warm weather, you should let in for 3 to 4 days.

Here is a video demonstration of blanching.
