Fine-flavored, mid-season leek variety for harvest through autumn. Leaves have a medium-green color and a broad white shank of medium length. Autumn Giant can winter in mild climates, but should be harvested by December elsewhere. (100-120 days)
Sow seed indoors in late winter. Sprinkle on soil surface, barely covering and keep moist until the thread-like seedlings emerge. Grow in full sun and cool conditions with temps under 75 degrees Fahrenheit. Set seedlings outdoors 6 to 8 weeks prior to last frost in rich, finely worked garden soil. Plant in rows one foot apart and space 6-inches between seedlings in the row.
