HEIRLOOM 1800s This variety is described by DM Ferry as a "second early variety", not as early as some, but much earlier than the late varieties. This is named after a coastal town on the Zuidersee in Holland. The round heads run 6-10 pounds and are a lovely dark blue-green in color. The delicious cabbages are vigorous, spreading, and resist splitting. 100 seeds.
Indoors- 4-6 weeks before last frost and 1/4” deep with soil temperature at 65-75 degrees. Liquid fertilize seedlings every 7-10 days. Transplant out just before last frost.
Outdoors – Early spring until mid summer for fall crops. Plant 1/2” deep, 12-15” apart for small headed varieties and 20-30” for large headed varieties
Harvest- If the heads feel solid by pushing on them lightly they are ready to harvest. Harvest as soon as possible for early varieties to prevent splitting. Later maturing varieties will hold longer.
Tips- Mulch, provide fertilizer, and adequate moisture for optimum growth.
