Giant Sequoia

Place the seeds in a glass of water for 24 hours.
Take the seeds and place them in a wet napkin(paper towel) and fold it. Put the paper towel in a nylon airtight bag and place it in the refrigerator for at least a month.
Put the seeds in pot filled with soil and place the pot in a sunny spot but do not expose the small flowers to direct sunlight at least until leaves start coming out.
You need to keep the soil damp but do not overwater.
