Brussels Sprouts Long Island Seeds

Sowing: For optimal flavor, it's best to sow Brussels sprouts seeds late in May or early in June to ensure exposure to frost. Plant Long Island Improved Brussels sprouts seeds at a depth of approximately 1.2 centimeters in the soil. When the seedlings reach a height of 15 centimeters, either transplant them or thin them out, spacing them 60 centimeters apart. Ensure the soil remains consistently moist around the seeds.

Growing: Apply mulch to retain soil moisture and carefully remove weeds to avoid disturbing the plants. If strong winds pose a threat, provide support with stakes. As the leaves on the stem begin to yellow, remove them to promote unhindered development of the sprouts. In case of aphid infestation, use a strong stream of water from a hose to eliminate them.

Approximately four months after transplanting, the first sprouts should be ready for harvesting. Twist the sprouts off the stem from the bottom upwards, aiming for those around 2.5 centimeters in diameter for optimal tenderness. To extend the harvesting period after frost, hang the entire plant upside down in a cool environment; the sprouts will continue to mature for several weeks. Long Island Improved sprouts freeze well.

Since seed heads won't develop until early spring, overwintering the plant is necessary. In colder climates, this involves digging up the plant and storing it, including the stem, in moist sand at a temperature of approximately 4 degrees Celsius. Replant the sprouts 3-4 weeks before the last spring frost. Allow the remaining sprouts on the plant to flower, mature, and fully dry on the stem. Monitor the seed heads closely, as they will open once dry and brown, ensuring timely seed collection before they fall to the ground. Store Long Island Improved Brussels sprouts seeds in a cool, dry location for up to five years.

Planting Methods: Brussels Sprout Long Island can be planted using direct seeding or by transplanting seedlings. If starting from seeds indoors, plant them at a depth of approximately 1 centimeter in seed trays or pots filled with well-draining soil. Transplant the seedlings outdoors once they have developed several true leaves, spacing them about 60-75 centimeters apart.

Blooming Season: Brussels Sprout Long Island typically does not produce flowers until it reaches maturity, which occurs approximately 100 days after planting. The blooming season usually occurs in late autumn to early winter.

Planting Season: Brussels Sprout Long Island is best planted in late spring or early summer, depending on the climate. In temperate regions, seeds can be sown directly in the garden after the last frost date. For areas with shorter growing seasons, starting seeds indoors 6-8 weeks before the last frost date allows for earlier planting outdoors.

Latin Name/USDA Zones: The Latin name for Brussels Sprout Long Island is Brassica oleracea var. gemmifera 'Long Island'. It is suitable for USDA Hardiness Zones 3-9.

Sunlight Required/Height: Brussels Sprout Long Island thrives in full sunlight, requiring at least 6-8 hours of direct sunlight per day. The plants typically reach a height of about 60-75 centimeters when fully mature.

Shelf Life After Test Date: The shelf life of Brussels Sprout Long Island seeds after the test date varies depending on storage conditions. When stored in a cool, dry place away from moisture and sunlight, the seeds can remain viable for up to 3-5 years after the test date.

Seed Type: Brussels Sprout Long Island seeds are typically classified as open-pollinated or heirloom seeds, meaning they can be saved and replanted in subsequent seasons while maintaining their desirable characteristics.

Soil Type: Brussels Sprout Long Island grows best in well-draining, fertile soil with a pH level between 6.0 and 7.5. Amend the soil with organic matter such as compost or aged manure to improve fertility and drainage.
