Growing Recommendations:
1. Soak seeds in hot (but NOT boiling) water for about 12 hours.
2. Seeds that have been successfully pretreated will swell to 3x their original size. Sow the swollen seeds 1/4" deep in sterile seed-starting soil. Repeat hot water treatment with the same seeds up to 3 more times, immediately sowing seeds as they swell.
3. Place seedling trays in a well-lit location, away from hot, direct sunlight.
4. Germination will occur in about 10-14 days after pretreatment. Some seeds will sprout all at once; others may take longer to break dormancy. Be patient and do not discard your seeds prematurely! :)
5. Transplant seedlings to their permanent location when they have their 2nd set of leaves, and after all chance of frost has passed.
Germination: 85%
