When looking for good companion plants to go alongside your Brussels sprouts crop there are some key things to consider. First, Brussels sprouts are heavy feeders and take a lot of nutrients from the soil.

The second thing consider is that Brussels sprouts are a cool season crop and will appreciate a little shade from neighboring crops during the hottest months of the year.

Try Leafy Greens When Companion Planting for Brussel Sprouts
