Long Island Improved Brussels Sprouts (Brassica oleracea) is a classic heirloom variety prized by home gardeners for its compact growth habit and reliable yields of flavorful, bite-sized sprouts. This cold-hardy selection performs well in fall and winter gardens, where light frosts are said to sweeten the sprouts. The plants grow upright and stay relatively tidy, making them a good choice for smaller vegetable plots, raised beds, and edible landscapes.

Whether you are planning a traditional holiday harvest or want a steady supply of fresh sprouts through the cooler months, Long Island Improved is a dependable open-pollinated variety that has been grown for generations. Start seeds indoors or sow directly in the garden, and enjoy the satisfaction of harvesting sprouts from your own backyard.

Planting & Care

For best results, start seeds indoors 6–8 weeks before the last expected spring frost, or sow directly outdoors in late spring to early summer for a fall crop. Sow seeds about 1/4 to 1/2 inch deep in a seed-starting mix or well-prepared garden soil. Keep the medium consistently moist but not waterlogged, and provide temperatures around 65–75°F for reliable germination. Once seedlings have several true leaves and are hardened off, transplant them to the garden, spacing them 18–24 inches apart.

Brussels sprouts thrive in full sun and fertile, well-drained soil. Water regularly to maintain even moisture, and apply a balanced fertilizer or compost as needed. Mulch to conserve moisture and suppress weeds. As the plants grow, you can remove lower yellowing leaves to encourage airflow and sprout development. Harvest sprouts from the bottom of the stem upward when they are firm and about 1–1.5 inches in diameter. Frost tolerance allows for extended harvest into late fall or early winter in many regions.
