depends on type small or large leaf? deciduous or evergreen?

Yes. I am interested in the answer to this question as well? In my case it would be the 'Rhododendron Catawbiense'. An evergreen which is native to Western North Carolina Mountains.

Thank you.

This site might help you out a bit:

Here is a link that might be useful: The Willow Garden

if they are not very upright and you can bend a branch to the ground, scratch the portion that will be in contact with the ground, mound a little dirt over it, and place a rock on it to keep the bent branch in place. check for roots next fall.

They are small leaf, evergreen. They are very upright and rather large specimens. Now what can I do?

Sorry for taking so long to get back here, but I did not know I had mail here. Please send answers to: lhendri479@aol.com

Thank you all very much, and Sowobsessed - thank you for the link. I will certainly read it.

i think i would investigate air layering.
