Direct Sowing: For direct sowing, plant ‘Long Island Improved’ seeds outdoors in mid-spring, after the last expected frost. Sow seeds ½ inch deep and 2-3 inches apart in rows spaced 24-36 inches apart. Germination typically occurs within 7-14 days. Brussels sprouts prefer rich, well-drained soil and benefit from consistent moisture, so regular watering is essential. Thin seedlings to about 18-24 inches apart once they are established to allow room for growth. Expect to harvest in about 90-100 days.

Early Sowing for Seedlings: To get a jump start, sow ‘Long Island Improved’ seeds indoors 6-8 weeks before the last expected frost. Plant seeds ½ inch deep in seed trays filled with quality potting mix, maintaining a temperature of 70°F – 75°F for optimal germination. Once seedlings have a few true leaves and the danger of frost has passed, transplant them outdoors, spacing them 18-24 inches apart in rows. Water well after transplanting to promote strong root establishment.

Harvesting: ‘Long Island Improved’ Brussels sprouts are ready to harvest when they are firm and about 1-2 inches in diameter, typically around 90-100 days after sowing. Starting from the bottom of the stalk, twist or cut the sprouts off, taking care not to damage the remaining sprouts. Harvesting can continue through late fall, as the sprouts often taste sweeter after a frost, providing a delicious addition to winter meals.
