Planting Tips:
Start Long Island Improved Brussels Sprouts seeds indoors 6–8 weeks before your last expected spring frost, or direct sow outdoors when conditions are suitable. For a fall crop, start plants early enough for sprouts to mature during cool autumn weather.

Plant in fertile, well-drained soil in full sun and provide consistent moisture throughout the growing season. Give plants adequate spacing to develop strong stalks and good air circulation.

Sprouts develop along the stalk and are generally ready to harvest when they are firm and about 1–2 inches in diameter. Begin harvesting the lower sprouts first and work upward as the remaining sprouts mature. Flavor can become sweeter after exposure to cool weather and light frost.

🌱 Container Growing: Brussels sprouts can be grown in large containers, although their size and long growing season make garden beds or raised beds especially suitable. For containers, provide plenty of root space and good drainage.
