How to Grow Brussel Sprouts in Pots

Most gardeners battle with space and that is why knowing how to grow Brussel sprouts in pots is important. Here are tips on growing Brussel sprout plant in pots:

  1. Get a pot with a depth of 12 inches and a diameter of 12 inches. Get a slow-releasing fertilizer, preferably 14-14-14, take one and a half spoons, and mix with your potting mix. Pour water into the pot until the soil is saturated, and extra moisture starts draining out of the pot’s bottom.
  2. Plant just one seedling of Brussel sprouts in the soil. Make sure you place it as deep as it was when it was in another container.
  3. Keep the pot where it can get access to bright sunlight all day long. Let the plant start getting the sunlight after planting.
  4. Touch the soil with your hands every day. Add more water whenever the first inch of the soil has become dry. You need to know that soil in the pot dries out quicker than the soil in the garden or ground. During hot weather, you should water the Brussel sprouts every day.
  5. Get a 15-30-15 fertilizer and dissolve just one spoon in three liters of water. Add the solution to the Brussel sprouts once every fourteen days. It would be best if you started watering the Brussel sprouts after six weeks of planting.
  6. When considering how to grow Brussel sprouts, know that the Brussel sprouts need to be constant watering during hot weather, and this will leach nutrients out of the soil. What this means is that you have to reapply fertilizer periodically so your plant does not lack nutrients.
  7. Always spay attention to the plant to know when the leaves start showing up. Once they do, remove the last 6 to 8 leaves growing on the stalk of the plant. Removal of the leaves will make the plant channel every energy into the development of sprouts.
  8. As soon as the sprouts form and reach half the mature sprout size, cut the stalk’s head, close to the tip, below the stalk’s growing point.
  9. When the Brussel sprouts mature, turn the sprouts off from the stalk. You know mature Brussel sprouts when its diameter has reached one or two inches.
  10. Start harvesting the sprouts from the stalk’s bottom and higher as each sprout mature-sprouts in the lower part of the stem mature first before the ones above them.
