Product Details

Modern chefs have transformed this historically disliked vegetable into a much-sought-after food that is delicious deep fried, steamed, or roasted. Give them plenty of water, nutrients, and time to grow before they begin forming sprouts. Covering plants with row covers after sowing/transplanting will help exclude pests. You can leave plants in the garden into the winter, as they are hardy to 10°F; frost actually improves the flavor. The plants resemble little palm trees.

Growing Info

Harvesting: Brussels sprouts start maturing from the bottom of the plant to the top. Buds should be picked when they are firm and about the size of a large cherry, between 3/4" and 1" in size. Break off the leaf just below the buds and snap or cut off the sprout. Brussels sprouts can be left in the garden through a freeze, which sweetens the flavor.
