Hi Kay,

Thanks for you ideas.

Right now I am trying to start Swedish Columnar Aspens. If successful,
I want to try it on other trees, my next try would be on an old
Colerado Blue Spruce, then on Poplar.

This is not theoretical, I am trying to get a lot of new tress started
for putting on a vacant property I am buying out at the lake.

Thanks

Roger

Hello,

I was told that I could start a tree from a leaf by cutting the stem at
an angle,putting it in soil (mostly vermiculite) and keeping it moist.

I tried about 15 leaves like this and they are all almost dead now.

You need cells that are capable of growth and division, called
"meristem cells" -- these are not present in mature leaves.

A few methods of vegetative propagation you can try with trees:
stem cuttings
stooling
air layering

Age of the wood you're using, how the wood is treated, and season all
make a big difference with these techniques, as does the species.

What species are you trying to propagate? Or is this more of a
theoretical question?
