I'm new but I've been doing lots of reading and here's what I plan on doing but I wanted to run it by you guys first to make sure I'm not way off base.

I have a new Olympian tree that I want to cut an activly growing branch off and root it.  The branch is about pencil thin and only 7 or so inches long; one of the little suckers at the bottom.

I plan on cutting off all the leaves except for the little ones at the tip and inserting it at least half way into a mix of moistened 50/50 perlite and UPM in a gallon container with a 1 or 2 gallon plastic bag over the top, possibly with a bamboo shoot to keep the plastick off the cutting, and putting it in the warm garage.

Any of you guys have success with this?  My only initial concern would be that the garage will get too hot?  It's July and typically 90+ degrees in there during the day.  I also have a shaded patio where I could put it.

Thanks and I really appreciate everything I learn from all you guys!

John,
An airlayer would be a much better approach, it is easy to loose a cutting

I agree it would too, but I'm just not sure I have enough space in the bottom of the pot to set up an air layer for it.

Please post a pic, I am sure there are experienced people in here who would recommend something.
I rooted green cuttings last year but I removed all the leaves except the smallest one at the top. They definitely need heat and moisture.

I'll see what I can do about getting a couple of pics.

What you are planning to do is my method. I get nearly 100% good results. Just don't put it in the garage. No heat needed anywhere in the US at this time. It does need light. Put it in the shade with indirect light.

I have a perfect spot then. Here's a pic of the stem.
