Small Gardens?
Yes
Containers?
Yes

For one broccoli plant, you'll need a pot that is at least 10" deep and 12" wide, but the deeper the better. 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 broccoli plants at least 18 to 24" apart. Although broccoli is a cool weather plant, it loves sunshine so be sure to place the container in an area with access to at least 3 hours of full sun a day.
