Choose a large container (at least 12 inches deep and 18-24 inches wide) with good drainage and use rich, well-draining potting soil.

Growing Tips

Watering: Keep soil evenly moist, aiming for about 1 inch of water per week. Mulching helps conserve moisture and controls weeds.
Fertilizing: Apply a balanced fertilizer every 3-4 weeks to support healthy sprout formation.
Cold Tolerance: Long Island Improved Brussels sprouts are hardy and can be left in the garden through light frost, which enhances the flavor.

Harvesting and Storage

Harvesting: Begin harvesting from the bottom of the plant upwards once sprouts are firm and about 1-2 inches in diameter.
Whole Stalk Harvest: For a single harvest, cut the plant’s top off three weeks before the desired harvest to encourage uniform maturity.
Storing: Store fresh sprouts in a perforated plastic bag in the fridge for up to two weeks.
