Heck no! Some trees (like Bristlecone pine, I believe) normally germinate only when there's been a fire that burns the pinecones open to release the seeds. Some (like silver maple) will grow easily anywhere, such as your gutters, sidewalk cracks, or in your own crack if you leave it there a few days :biggrinbounce2:
Some trees, (like Sugar Maple) need a certain number of days at a certain temperature for their seeds to sprout. I tried to sprout these very seeds in a plot outside, and failed miserably. Then I tried to germinate them the way we do our garden veggies - inside with the trays, and also with the wet napkin in the baggie. No luck. I did some research and found out they needed a few weeks under 30 degrees, so I stuck them in the fridge. Still no luck.
No, not all tree seeds are created equal. And then after that, once they're germinated, then you've got the various acidity of the soils, elevation, temperature, humidity, etc. etc. which causes the tree to grow well or poorly (or not at all). It's a fascinating world which I've only peeked into a little bit.
