Brassica oleracea var. gemmifera
Brussels sprout is a tall annual brassica that carries its small, cabbage-like heads along an upright stalk. At about 3 feet tall, it becomes a substantial presence in the fall vegetable garden rather than a quick filler crop. Brassica oleracea var. gemmifera needs a long run to maturity, so give it a dedicated place where its leafy form can remain in place through fall and into early winter harvest.
Set Brussels sprouts toward the back or north side of a bed so their height does not crowd lower crops. Arrange plants in a simple block or short, accessible row, with the outer side facing a path for picking sprouts from the bottom of each stalk upward. Beans, celery, dill, onions, sage, thyme, lettuce, and beets can be included nearby; keep strawberries, tomatoes, and peppers in separate areas of the plan.
Plant Brussels sprouts 2 feet apart, center to center. Each plant can spread about 2 feet wide, so this spacing creates a full, nearly continuous canopy as the crop reaches size. Use one or two rows rather than packing plants into a narrow mixed bed, and leave an open working edge beside the planting for watering, weeding, and harvest access without leaning across the stalks.
Give this crop a full-sun position and regular water throughout its long season. A well-drained bed that also holds moisture supports steady growth; avoid placing it where irrigation is difficult to deliver evenly. Deep watering is more useful than frequent light sprinkling, particularly when the soil is sandy or dry weather persists.[1]
Plan the bed around a fall to early-winter harvest, allowing roughly 95 days to maturity. The plants tolerate cool conditions and can remain productive after light frost, with flavor improving as fall weather cools. Harvest begins at the lowest sprouts and moves upward over time, so keep the row accessible late in the season rather than replacing nearby paths or planting beds.[1][2]
Do not use the same spot immediately after other cole crops such as cabbage, broccoli, cauliflower, kale, collards, mustard, turnips, or rutabaga. A four-year break from those related crops helps make the Brussels sprout bed a better fit in a rotation plan. Mark the planting on the garden layout so the following seasons can be planned around that interval.[1]
