Germination Information
Pre-treatment: 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 were covered with polyethlene bags and placed in the walk-in cooler for 90-days.
Establishment: One flat was placed directly in the greenhouse after being sown. This flat had zero germination. Seedlings grew slowly in the spring.
