Brussels Sprouts are hardy, as well as temperature-sensitive. They produce the most flavor when grown in cool weather. Brussels sprouts are cold-hardy to 0°F (-18°C) and their flavor is enhanced by frost. They do not like hot long summers.

Containers?
Yes

For one Brussels Sprouts plant, you'll need a large pot that is at least 12 inches deep and 12 inches wide. Fill with a mixture of potting soil and compost and keep the soil moist but not overly wet. If you are using a larger container, be sure to space your Brussels Sprouts plants at least 24 to 36 inches apart. The benefit of growing Brussels Sprouts in a container is that it can be moved to avoid too much heat, which may prolong the season.
