Where Do Brussel Sprouts Come From?

It descended from wild mustard that grew in the Mediterranean and was first cultivated in Ancient Rome. However, later on it was refined through gentle selection to create the veggie we know and love today. As this selecting was done near Brussels, Belgium, this is where the name comes from. The plant made its way to North America around 1800. Part of the cabbage family, Brussels sprouts can be grown in just about any home vegetable garden, or even in a pot, as long as you have patience.

What Month Do You Plant Brussel Sprouts?

Plant seedlings in the garden or in a pot six to ten weeks before the first expected frost. Brussel sprouts are best as a fall crop with a long growing season that starts 6 months before your first fall frost. You can also plant them in the early spring too – February or March. However, keep in mind that sprouts that ripen in the heat don’t taste nearly as good as those that ripen after a light frost.

  • In regions with cold winters, where winter temperatures are often below freezing, start seeds in early to mid-summer. Plants will mature for a mid-fall or early winter harvest.
  • In regions with mild or warm winters, where winter temperatures are occasionally or rarely below freezing, start seeds in mid- to late summer. Plants will mature for a mid- to late winter harvest.

Choose and Prepare a Planting Site

Preparing The Seeds

Sprouts are a brassica. This means they need the same process for starting like broccoli, kale, cauliflower, and cabbage. People who are in areas with colder weather – start your seeds inside. Do this at least two to three weeks before spring’s last frost. If the place you live in has a mild climate – start mid-summer in the garden. If the winters are warm, and you never have freezing temperatures – plant mid-/late-winter and in the garden. However, if you have hot weather, keep them inside to protect them from the heat.

How To Start Seeds

  1. Get a pot. Fill it with sterile seed starter.
  2. After this sow them. They should be two to three max in every spot. Go at least two inches deep.
  3. Use a sprayer or mist to water them. The soil, especially should be kept moist in the beginning.
  4. Keep them at a temperature of 70-75 °F or 21-23° C. It will take between five and seven days from them to start popping up.
  5. Once the leaves have come up, make sure to remove any extra seedlings. Use a pair of scissors or snip.
  6. When they get two to four leaves, pot them in bigger pots.

Growing Brussels Sprouts

  • Young plants need to be thinned from twelve to twenty-four inches apart. Do this when they become six inches tall.
  • Use a nitrogen-rich soil after thinning them to make sure they are fertilized. Do this between three and four weeks.
  • Cover them with some mulch to keep the sprouts cool during the summer.
  • Keep them well watered if you are planting them during the summer.
  • The roots are shallow so do not disturb the soil as you can damage them.
  • Get rid of any yellow leaves in the bottom. This will help the plant get more sunlight.
  • Cut the leaves in order to encourage the sprouts to grow faster.

Harvesting Brussels Sprouts

Brussels start maturing from the bottom upwards. That’s why you should start picking from the lowest sprouts first. You want to pick them before the buds start to turn yellow and begin to open. They should be firm, bright green, and about 1 to 1.5 inches in diameter. Snap them off with a sharp downward tug. Make sure to not harvest all the sprouts at once. This is because all the sprouts on the stalk do not mature at the same time.

Storing Brussels Sprouts

Washing the sprouts before storing them is a big no-no. Wash them right before using them. You can keep freshly picked brussels in a plastic bag for up to five days. But they must be kept in the refrigerator. After a moderate frost, you can pull up the entire stalk and hang the stalk upside down in a cool, dry basement or garage or barn. This way they can stay fresh for about a month.
