Why is my Broccoli Flowering? 3 Major Reasons

Why is my broccoli flowering? If you decide to grow broccoli, you should understand that this plant is not for beginners. It has quite a short timeframe to grow in, it can be fickle, and it needs to be grown in well-drained soil.

In addition, many gardeners have to deal with broccoli bolting. Bolting is when a broccoli flowers and produces seeds.

If you wonder why your broccoli began flowering, keep reading this article.

 

Why Is My Broccoli Flowering?

Broccoli can start flowering for multiple reasons. The most common reasons are the soil is too cold or too hot, or your plant is under severe stress. Usually, heat is the main reason broccoli starts to flower.

The Reasons for Broccoli Flowering

Let’s discuss the reasons for a broccoli head to bolt in detail:

 

1) Heat

High temperatures are what commonly cause broccoli flowering. If you decide to plant and grow broccoli, the most important thing you need to remember is that it is a cool-season plant that does not like temperatures above 75 degrees Fahrenheit (24°C).

If the temperature gets higher than that, the roots of the plant will overheat. Therefore, it is not recommended to grow broccoli in warmer states.

 

2) Issues with Watering

Inconsistent watering is another common cause. Just like beets or tomatoes, broccoli does not like fluctuating soil moisture.

Therefore, it is recommended to water your broccoli regularly and check the soil, especially if your broccoli plants grow in containers.

 

3) Stress

If your broccoli plant is stressed, it might start flowering. One of the common stressors is overcrowding plants.

The best thing you can do is to space broccoli seedlings or seeds at the appropriate distance. The best distance to plant broccoli is 12 to 18 inches apart.

Other causes of stress are weeds and insect damage. Therefore, if you notice weeds, you must pull them as soon as possible.

Also, do not ignore the pest issue and try to eliminate insects immediately. Your plants can also be stressed because of the lack of nutrients, which is especially common during warmer months.

 

What to Do to Prevent Broccoli from Bolting

There are several things you can do to prevent or stop broccoli flowering:

 

1.Add a Layer of Mulch

Mulch helps prevent the roots of your broccoli plant from getting too hot.

One of the best types of organic mulch that you can use is straw. You should spread it around your broccoli to insulate the ground and protect the soil from direct sunlight.

2.Keep the Soil Healthy

Healthy soil helps your plant grow and prevents various issues, including bolting.

 

3) Create Shade

Broccoli plants dislike direct sunlight, so creating shade can greatly help. You can create shade in various ways.

You can use a patio umbrella, apply a shade cloth, use row covers, or surround your broccoli plants with other higher plants that will create shade.

Since broccoli don't like sunlight, cover them with a patio umbrella, shade cloth, row cover, or grow plants that create shade

4.Grow a Broccoli Plant Resistant to Bolting

Some broccoli varieties are more resistant to flowering than others.

So, if you do not want to worry about bolting and ways to prevent it, planting bolt-resistant broccoli varieties might be a good idea.

 

5.Harvest Early and Frequently

Since broccoli is a cut and come against type of vegetable, you can harvest it often.

Many gardeners agree that early and frequent harvesting is a very effective method to prevent bolting.

Signs Of Broccoli Bolt

The sooner you notice broccoli bolting, the better. Here are the main signs to watch:

  • Your plants start shooting yellow or white flowers
  • Your plants start stretching and growing upwards.

 

Can I Still Eat Broccoli That Started Flowering?

The short answer is no. Flowering broccoli is not fit for eating.

It is still edible, but florets and leaves will likely taste bitter, and stems and stalks will be tough and dry. However, if you catch your flowering broccoli early enough, there might be some hope, and the heads of your plant might be good to eat.

 

Can I Save My Flowering Broccoli?

Unfortunately, if the bolting process has already started, it is impossible to stop your plant from flowering. This is because the structure of the plant that starts flowering changes immediately.

Trying to remove flowers will make them grow even faster. However, bolting broccoli can still benefit your garden or backyard by making your green landscape look more beautiful with yellow flowers.

 

Will My Broccoli Plant Grow Again After Bolting?

Once your broccoli plant begins to bolt, the main head will most likely stop growing because the energy of the plant will start going to seed production and flowers.

However, if you cut the main head, your broccoli plant will start producing side shoots, and you will see new small florets growing.

 

Frequently Asked Questions About Broccoli Flowering

 

Is it possible to prevent broccoli from flowering?

You can prevent it by planting it in cooler weather, mulching, watering it regularly to keep it hydrated, fertilizing regularly, cutting off flowers as soon as possible, and thinning your plants.

 

What other problems with your broccoli plants can you have?

There are other issues with the broccoli plants you may encounter. For example, your plants can start falling over if they grow too tall; they can produce smaller heads or not produce heads at all.
