500 Seeds Cabbage Savoy Italian Minestrone Soup Cooking Non-GMO Sowing: Start your Savoy Cabbage seeds inside 8-12 weeks before the last spring frost, planting them in rich soil 1/2 inch deep and 2 inches apart. Because the first crop of cabbage should mature before the heat of summer, plant your winter cabbage seedlings about 4 weeks before the last expected frost; set them 12-18" apart in rows 3-4' apart, burying the stems about halfway up. For a fall crop, direct sow or transplant seedlings in midsummer. For companion planting benefits, plant Savoy Cabbage seeds with aromatic herbs or potatoes; avoid planting them with tomatoes or pole beans. Herbs such as thyme, peppermint, sage, and rosemary will repel the destructive white cabbage moth Growing: If hard frosts come, cover the young plants. Mulch around them to regulate soil temperature, and keep the soil moisture even to prevent the cabbages from splitting.
