Savoy Cabbage

Savoy cabbage is a winter-hardy variety of Brassica oleracea distinguished by its deeply crinkled, dark emerald-green outer leaves and pale, tender inner head. The texture is crunchy yet slightly elastic, with a mild, sweet flavour that intensifies after frost. Heads typically weigh 1–1.5 kg and have a slightly flattened, compact form. It thrives in full sun and tolerates cold well, making it well suited to Nordic growing conditions.

Growing

Start seeds indoors or in a cold frame at around 20 °C, sowing 1 cm deep and spacing seeds generously to allow air circulation. Germination takes 4–7 days. Grow seedlings at a minimum of 14 °C in a bright, cool, and well-ventilated spot to prevent drawn-out, leggy growth and damping-off. Harden off gradually before transplanting outdoors once the risk of hard frost has passed — typically once nights stay reliably above 8 °C. Set plants 30–40 cm apart in the row, with rows 50–70 cm apart. Early sowings produce summer heads; later sowings yield autumn and winter harvests.

Care

Water consistently to keep the soil evenly moist but never waterlogged; irregular watering causes split heads. Apply a balanced nitrogen-rich fertiliser shortly after transplanting, then supplement with potassium as heads begin to form to improve density and cold tolerance. Stake or earth up plants in exposed positions to prevent wind-rock. Watch for cabbage white butterfly and aphids; use fine mesh netting as physical protection. Remove any yellowing outer leaves to improve air flow.

Harvest

Cut heads when they feel firm and dense under hand pressure, with outer leaves tightly wrapped around the head. Late-season varieties improve in flavour after the first frosts darken the outer leaves. Harvest by cutting the stem cleanly at the base with a sharp knife. Leave the stump in place if you wish to harvest small secondary side-shoots later in the season.

In the kitchen

Savoy cabbage leaves are versatile: shred raw into slads and coleslaws for crunch, or wilt briefly in butter or olive oil as a simple side. The pliable leaves are ideal for stuffed cabbage rolls, as they wrap without cracking. Add to soups, stews, and gratins where it holds its texture better than standard white cabbage. Slice thinly for stir-fries or braise whole wedges slowly in stock.

Storing

Heads keep for 2–4 weeks in the refrigerator, wrapped loosely in a plastic bag or damp cloth. For longer storage, place unwashed whole heads in a cool, dark cellar at 0–4 °C with high humidity, where they can last several months. Shredded or blanched leaves freeze well for up to 12 months. Do not store cut leaves at room temperature; they wilt rapidly.
