Stratify for 60 days in the dark at room temperature follwed by a 180 day cold moist stratification in the refrigerator. Start checking for germination after 120 days. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Fully Controlled Greenhouse. Sowing Method: Transplanting Germinants. 8 grams of seeds are sown per flat containing Sunshine Mix #4 Aggregate Plus (peat moss, perlite, major and minor nutrients, gypsum, and dolomitic lime). Seeds are covered with media. Flats are watered in with an automatic mist and irrigation system. Seeds are sown on June 1st. % Germination: 75% |
