Question
It rings a bellwith me, that some where I heard that in order for a seed to germinate it must undergo extreme heat as generated by forest fire.  I have 4 seeds and would like to try my luck at growing a really big tree.  To date I have been able to start a Douglas Fir from seed. I only have one but it is in its 3rd year and it is now about 18 inches high.  

Answer
Hi John,
Thanx for your question.  Yes, there are some plants that benefit from fire in order to stimulate germination.  I can think of Protea (a South African flower/shrub) as a perfect example but with the sequoia you can start the seed in a a pot of moist (not soggy) potting soil and keep at a temp of 60-70 degrees and germination will occur in a few weeks.  Germination rates tend to be poor so the more seed you have the better.  Gently prick out the seedlings after they have a few sets of leaves and pot them up in separate pots.  Don't put the seedlings out if it is going to get cold.  Wait until the next spring and place the pots in a shaded, protected area for 10 days and then you can plant in direct sunlight.  I hope this helps.
