Instructions:
We recommend using the following to sow the seeds:
Pre-soaking and stratification is option, but helps with germination. Pre-soak by placing the seeds in room temperature-warm water for 24 hours. Stratify by placing in soil or sphagnum moss in a baggie or tupperware container and placing the container in a fridge for ~1-2 weeks. From there, sow the seeds in a greenhouse and keep warm and brightly lit. Acclimate seedlings to full sun gradually, or keep under grow lights.
