Winter Grape seeds benefit from moist cold stratification before sowing. Clean the seeds, place them in a slightly moist growing medium, and refrigerate for approximately six weeks. After stratification, sow them in well-drained potting mix and maintain consistent moisture. Germination commonly occurs in spring, although some seeds may take longer.
