Jade Cross Brussels Sprouts is a hybrid, early maturing variety. As a result, it can be planted later in fall than most varieties, especially in cooler climates. Jade Cross was a 1959 All-America Selections winner for taste and performance. Plants produce 30″ stalks that are loaded with “mini cabbages” or sprouts. Sprouts are consistently around 1″ in diameter and uniform in size. Sprouts may be harvested individually, or wait until full maturity and harvest the entire stalk. Jade Cross Brussels Sprouts have excellent flavor for roasting or sauteing, but also hold well when frozen. Blanch, dry and freeze for Brussels Sprouts year-round.
Brussels sprouts may be direct-seeded, but perform best when transplanted. Transplanting allows for more consistent plant spacing, and prevents Brussels sprouts seedlings from competing with weeds in the early stages of the plant. We recommend starting transplants 3-4 weeks before the desired outdoor planting date. Brussels sprouts transplants grow great in our heavy-duty seed starting trays, where they develop a solid root ball with roots that are trained to grow downward. Plants are ready to go in the ground when they can be easily pulled from the cells in the seed starting tray.
Brussels Sprouts perform best in cooler weather and will have better flavor if the plants have experienced several frosts throughout the growing cycle. To maximize sprout growth, cut or crop the top leaves once sprouts start to develop along the stalk. We suggest using a pair of pruning shears or loppers to do this, as stalks can be quite fibrous and tough to cut with a knife. This will devote more of the plant energy to the sprouts and less to growing more leaves. Side leaves may also be removed to improve sprout development.
