Planting & Care

Soil and Water: Brussels sprouts require fertile soil high in organic matter and nitrogen. They perform best with a pH of 6.5 and consistent moisture.

Planting and Growing: Best grown as a fall crop, start seeds indoors in June to set out transplants about 100 days before the first frost. Sow in flats and set out plants when then have 4-5 true leaves. When the lower sprouts are about 1 inch in diameter, remove the top most growing tip of the plant. This will allow the top sprouts to develop.

Harvesting and Storage: Allow the plants to be exposed to a frost, this will improve the flavor of the sprouts. Pick the sprouts when they are about an1-2 in size. The lowermost sprouts mature first.
