How to Grow Attis
Brassica oleracea var. gemmifera
Attis is a unique variety of Brussels sprouts featuring small, tender heads that form along the main stem rather than the side shoots. Gardeners prize this cultivar for its reliable yield in cooler climates and its ability to withstand light frosts while developing rich flavor.
Starting Attis: indoors or direct sow?
🏠 Start indoors 4 weeks before your last spring frost, then move the seedlings outside.
If starting indoors, move seedlings outdoors once they have developed a few true leaves and the risk of hard frost has passed.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.5. As a cool-season crop, sow seeds directly outdoors or start indoors two to six weeks before your last spring frost date. Plant the seed at a depth of about one inch. Expect germination to occur within seven to fourteen days under optimal conditions.
Space plants eighteen to twenty-four inches apart in rows to ensure proper air circulation. While this variety does not require trellising, consistent moisture is vital; aim for one to one and a half inches of water weekly via deep watering. Apply mulch around the base to retain soil moisture and suppress weeds, feeding lightly if growth appears stunted.
Monitor closely for cabbage worms, flea beetles, harlequin bugs, and aphids, treating infestations early with organic controls. Watch for clubroot, black rot, powdery mildew, and bacterial leaf spot by ensuring good airflow and removing diseased leaves immediately. Harvest the small sprouts starting from the bottom of the stem upward approximately 118 days after sowing.
