If you intend to plant the Brussel sprouts with pots, you have to do so with an aged compost soil rich with nutrients. The Brussel sprout needs to get all the nutrients they can as soon as you plant them.

- 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.
- Keep the pot where it can get access to bright sunlight all day long. Let the plant start getting the sunlight after planting.
- 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.

- 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.
- 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.
- 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.
