This section will give a detailed explanation of how to grow Brussel sprouts in your garden. The tools required are easily accessible, and the process doesn’t take a lot of time.

Materials Needed to Grow Brussel Sprouts

To successfully grow Brussel sprouts in your yard or garden, here’s what you’ll need.

  1. A container 12 to 14 inches deep and 18 inches in diameter (one foot deep and one-foot wide container)
  2. 1-gallon container
  3. Brussels seedlings
  4. Potting mix
  5. Pruning shears
  6. A transplanting tool, e.g., a hand shovel
  7. Controlled release fertilizer
  8. Soluble fertilizer
  9. An area with access to adequate sunlight

Comparing Potting Soil vs. Potting Mix

Potting soil is simply dirt or ordinary soil. It contains decaying organic matter that adds nutrients to the soil, suitable for indoor and container plants. One of the best things about potting soil is that it is very cheap and lasts longer than potting mix.

But then potting soil can be bad for your plants as they are heavy and compact when waterlogged. Another issue is that potting soil is tightly packed together and not fluffy. This leaves little room for your plant root to grow. This problem also makes the soil poorly aerated; in general, potting soil is not ideal for seedlings.

Potting mix is specially designed for container plants. It includes compostable organic matter, peat loss, perlite, and vermiculite. Potting mix can also be custom-made for specific plants; a good example is a cactus or orchid.

Potting mixes have a lightweight and fluffy texture that makes it easy for plant roots to pass through easily; they also have a good drainage system that makes soil aeration possible.

With all of the above added, your soil has the right nutrient mix, drainage, water retention, and soil aeration, which is very important for the plant.

Growing Brussel sprout in a container means you have to use loose soil that creates room for root growth and proper aeration; the potting mix is the ideal soil for growing Brussel seedlings.

Soil Requirements For Growing Brussel Sprouts

Your soil needs extra attention as it needs to meet the requirements for growing Brussel sprouts. The soil pH should be slightly acidic at 6.5 or completely neutral at 7. 

Any other value above or below this is not suitable for Brussel sprouts to grow; your soil also needs a reasonable amount of organic matter to enrich the seedling and aid their growth.

Your soil needs to be moist at all times and not flooded with water. 

Brussel sprouts do well in free and aerated soil that is not compacted. This plant grows well under a temperature between 45 degrees Fahrenheit to 75 degrees Fahrenheit; they prefer to grow under a cool temperature as it improves their flavor; a hot temperature only makes them bitter.

Fertilizer Needs

Brussel sprouts are significant feeders and will need many nutrients to grow. You can consider adding well rotten manure to the soil mix or good compost; another option will be to use fertilizers like 10-10-10, 5-10-5, 5-10-10, 14-14-14 controlled-release fertilizer, or 15-30-15 soluble fertilizer. These fertilizers provide a constant supply of nitrogen to your plant.

  1. Seeds
  2. Potting mix
  3. Small plastic containers
  4. Scissors or a sharp knife.

Make holes underneath your container for proper drainage; if you grow Brussel sprouts inside your home, you will need a tray to collect the drained water.

Step Two:

Buy some potting mix as it is great for soil drainage and aeration. It also contains organic matter that supplies your plant with adequate nutrients.

Step Three:

After filling your container with ng mix, add 1½ tablespoon of 14-14-14 control release fertilizer to the mix. You can also choose to use organic fertilizers like manure and compost.

Step Four:

This is a step that some people skip during planting, but it is very important. Water your potting mix before planting the seeds. Knowing that your mix has received enough water will see water seeping out of the drainage holes.

Step Five:

Transplant your brussel sprout when it is about 5 to 7 inches tall. You can do this by using a hand shovel. And if your container is big enough, you can grow more than one seedling.

Step Six:

Keep your brussel sprout in an area with just enough sunlight; your plant should receive at least six hours of sunlight a day.

Step Seven:

Water your plant regularly; outdoor Brussel sprouts will need more water than those grown indoors. Your soil should be kept moist at all times; this does not necessarily mean watering it; you can keep it moist by misting it using a spray bottle.

You may have a problem telling if your soil needs moisture, so here is a simple guide on how to determine if your potting mix needs moisture.

Pick up a wooden stick and insert it into the potting mix. If damp soil particles stick to the wood, it is moist, but if dry soil crumbles off the wood easily, it needs moisture.

Step Eight:

After your initial fertilizer application, you should feed your soil some more nutrients six weeks after growing your Brussel sprout.

Mix 1tbsp of 15-30-15 Soluble fertilizer with 1 gallon of water; you can use this water to moisten your soil once every two weeks.

Step Nine:

When your plant begins sprouting, pluck off some of the lower leaves to focus the plant’s energy on sprouting. Using pruning shears, cut off the stalk just at the top of the plant. This should be done when your sprouts are about 0.5 to 1 inches in diameter.

Step Ten:

When your sprouts have finally grown to a point where It is 1 to 2 in diameter, you can now harvest them.
