Growing Area Preparation/
Annual Practices for Perennial Crops:		 Seeds were sown into cone-tainers filled with Sunshine #1 (a soil-less, peat-based media) amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats of cone-tainers were placed in a heated greenhouse for 2 months, and then a cooler for 2 weeks, then back to into a heated greenhouse.
Establishment Phase: Seedlings germinate after a 2 month warm stratification followed by a cool period. Seeds germinate best in cool temps (50-60 degrees), but will tolerate temps reaching into the 70's.
