Germination Information

Pre-treatment: Place the seed into finely woven mesh bags and then place the mesh bags into gallon freezer bags filled with wet soil mix. Place these in a cooler at 40° F for 90 days. After stratification treatment, transplant 3 to 5 seedlings into 10 ci conetainers filled with Sunshine Mix #4, and water heavily to prevent desiccation. No fertilizer is added to the soil mix.

Establishment: Seed was planted on March 22. Plants were fully established within 8 weeks. Beds are sown most commonly from late September through early November. Sowings from late February through mid-April are also successful, though first year crop weights from these spring plantings will be less than fall plantings. Individual plants die after 2-5 (or more) years. Typical lifespan of plantings is 3-4 years.
