Brussels sprouts are a long-season cool-weather crop, which makes Georgia timing especially important. They are usually most successful as a fall and winter crop: establish transplants while late summer is still warm, then let the stalks develop as temperatures cool.
Georgia's relatively mild winters create a useful cool-season growing window. UGA Extension includes Brussels sprouts among cole crops suited to winter production. Unlike quick greens, however, Brussels sprouts need patience: UGA's fall guide estimates roughly 90–100 days to maturity.
For fall gardens, UGA lists approximately August 30 through October 1 for transplants. Local timing matters. North Georgia gardeners need enough time for plants to size up before severe cold, while warmer parts of the state can have a longer cool-season runway.
Because they mature slowly, UGA North Georgia guidance recommends purchasing Brussels sprouts as transplants for fall gardens rather than starting too late from seed.
The edible sprouts form along a tall central stalk in the leaf axils—they are not tiny cabbages growing independently in the soil. The lower sprouts generally mature first, which is why harvesting begins near the bottom and progresses upward.
Brussels sprouts are Brassicas, along with cabbage, broccoli, cauliflower and kale. That family relationship is important when planning rotation because many of these crops share pests. Nearby flowers can increase garden diversity, but don't crowd the plants or sacrifice airflow simply to follow a companion-planting list.
Harvest sprouts when they are firm and well formed. Twist or cut the lowest mature sprouts first while leaving smaller upper sprouts to continue developing. Cool weather is part of the crop's natural season, so don't judge the plant by warm-season vegetable timing.
Imported cabbageworm, cabbage looper, diamondback moth larvae and aphids can attack this crop just as they attack other cole crops. Scout leaves and developing sprouts frequently. Row covers can help exclude pests early, and good rotation and garden cleanup reduce recurring pressure.
