How to Grow Brussel Sprouts: A Few Words on Weather and Soil

Before you rush down to your favorite nursery to get some Brussel sprout seeds, we need to make a few considerations on the best climate and soil types that favor the plentiful growth of Brussel sprouts.

  • Weather

Brussel sprouts love cool weather, as the small heads mature best in light frosty and cool areas. This is the reason why you should plant the Brussel sprouts in early spring or late summer for fall crops. Crops that mature in hot or dry weather will gain a bitter taste and a flimsy texture. However, do not forget that Brussel sprouts, just like any other vegetable, needs at least six hours of sun a day. In other words, make sure you pick a sunny place on your property to make sure your Brussel sprouts get the light and warmth they need.

  • Soil

You need to test the soil first before planting Brussel sprouts. This is a recommendation universal to any vegetable you plan to introduce in your garden, as the soil chemical makeup can make or break your crops. Brussel sprouts fare well in fertile, well-drained, moist soils. You need to establish a soil pH of about 6.8 for optimal growth and for preventing root diseases. Brussel sprouts love a soil offering them organic nutrients. Depending on the soil test results, you can amend the soil with nitrogen-rich nutrients. Composted manure, organic compost, blood meal or cottonseed meal are some of the solutions you can use to organically fertilize the soil and give your Brussel sprouts the growth foundation they need.

Brussel Sprouts Varieties

Seasoned gardeners recommend two Brussel sprout varieties that come with a set of features and benefits:

  • The Valiant variety yields consistent, uniform sprouts – recommended for gardeners and vegetable growers who want large productions.
  • The Jade Cross variety is resistant to some diseases – recommended for beginner vegetable growers who want resilient types first to get the hang of it.

Brussel Sprouts Planting

The Brussel sprout seeds should start indoors at least 6-8 weeks before the last spring frost.

  • If you bought Brussel sprouts seeds in a bag, make sure you plant them right away. Do not let them sit for too long and dry out in their package.

A few days before bringing out the Brussel sprouts seedlings from the house, fertilize the soil well.

  • Specialists recommend you use raised beds for Brussel sprouts. Cold season vegetables do well in raised beds, especially if you plant them outside when the temperatures are not yet consistent and the seasons are about to change.

If you plant the Brussel sprouts in rows or beds, keep in mind they are large crops, so they need plenty of space to develop.

  • Plant Brussel sprouts 24 inches apart in any direction in a vegetable bed.
  • Plant Brussel sprouts 36 inches apart in a vegetable row.

After you planted the seedlings, water the plants thoroughly. If the plants do not receive enough rain yet, make sure you water them on a weekly basis, giving them at least 1 to 1 1/2 inches of water.

  • If you want the best crop, make sure you also mulch the freshly planted Brussel sprouts. You need to keep the soil cool and the sprouts moist and nourished. For a boost of growth and health, you can also apply a starter fertilizer now.

Brussel Sprouts Long-Term Care

Now that you planted your Brussel sprouts, it is time to care for them properly. Some of the most important activities now are fertilization, watering, pest control, and physical protection of the roots.

  • Fertilization

Three weeks after you transplanted the Brussel sprouts seedlings you need to fertilize the soil. Specialists recommend you continue to use organic fertilizers and homemade soil amendments. Many people do not know how tall Brussel sprouts grow and what are the secret ingredients they need to yield good crops.

When properly spaced, fertilized and watered, Brussel sprout plants grow to 2 1/2 feet tall when they reach full maturity. In other words, if you want plentiful crops, you need to keep them nourished. The best approach to fertilization is to apply a nitrogen-rich organic fertilizer when the plants are 12 inches tall and then every three to four weeks.

  • Watering

Brussel sprouts can fare well without a strict fertilization program, but they will suffer tremendously if you do not give them enough water. Provide your Brussel sprouts with at least one inch of water per week. This is not negotiable (unless it rains and the weather compensates for the water).

You should also refresh the moist layer of organic mulch you applied after plantation regularly. You need to keep your sprouts cool and moist and protect them from unexpected extreme weather phenomena and pests.

  • Pest Control

Brussel sprouts are vulnerable to pests that usually attack the cabbage family members. Aphids, harlequin bugs, cabbage loopers, diamondback moth, imported cabbageworm, cutworms, cabbage maggot, thrips, and webworms are some of the main enemies of Brussel sprouts. Aphids are especially hard to deter. Specialists recommend you use organic pest control methods to get rid of unwanted insects. Using chemicals can endanger the crops as the substances infiltrate deep into the soil and water resources and the plants’ roots, turning them inedible.

  • Disease Control

Brussel sprouts are sometimes vulnerable to powdery mildew, white mold, rust, and clubroot disease, among others. If you want to treat the plants in an organic, safe manner, you should call for professional help.

how to grow brussel sprouts harvesting

Brussel Sprouts Harvest

You know you are ready to harvest when tiny cabbage heads are firm, green, and 1 to 2 inches in diameter. You can harvest the plants until the first hard freeze takes over the land. The harvesting technique is simple: twist the sprout gently, but firmly, until you remove it from the plant.

  • Remove the yellowing leaves when you remove the lower sprouts because the plant will continue to grow upwards and produce more leaves and sprouts.
  • If you cut off the top of the plant about 3 weeks before you want to harvest as you move into winter, you can trick the plants to mature all at once.
  • One healthy, well-grown plant can yield 2 to 3 pounds of sprouts; this is why Brussel sprouts storing should be on your list of top priorities.
  • If you still want to harvest deep into winter after the first round of harvesting, cover the soil with straw mulch or a groundcover/landscape fabric to keep the plants protected.

Brussel Sprouts Storage

Now that you have plenty of sprouts, you need to store them correctly. Naturally, you should eat them fresh, but if you obtained large crops, the refrigerator is your best friend.

  • Do not wash Brussel sprouts when you store them.
  • Put them in plastic bags while they are freshly harvested and unwashed.
  • Do not keep the sprouts in the refrigerator for more than five days – you progressively lose all those delicious vitamins and minerals. While all cabbage family member are quite resilient to being in the refrigerator for months, it is not a good idea to keep them that long.
