They don't grow well from cuttings. Named varieties are usually grafted onto seedling rootstock.

Go to http://wwwgardenadvice.co.uk/howto/gardenplants/cuttings_softwood/index.html and it will explain in detail how to take Acer cuttings.

I guess I'd better see that too!

Whoops! My computer says that there is no such page! Maybe misspelled?

No - I've just been there.

Aha! An elementary mistake on my part: I've just been cutting and pasting the address from the post, and the dot is missing from after the "www"! Oops!

There, that worked! So they use softwood cuttings! I'll have to try that.

Thank you, Nariz!

You're welcome. :o)
