Ok,

I'm a home owner that would like to Propagate a few Crimson King Maples.

I know you can't use the seeds to maintain the genetic sample.

asexual (vegetative) propagation which preserves the genes is needed.

How do I go about doing this? Can I cut a limb and get it to grow in some way? What is an easy method. I have done this with Lilacs but figure it won't work with a tree.
