question on propagating clematis vines

11 years ago

I posted the following over on the Clematis forum, and repeating my question here:

My project here is to cover the deer fence that surrounds my property with assorted clematis vines. So I need hundreds of the things.

I'm using pretty much the standard, recommended method for propagating clematis: one leaf, inter-nodal cutting 3-4 inches below the node, use Clonex rooting hormone, plant them in perlite, and use a covering dome. So I can get some 80+% of my cuttings to root - often spectacularly.

The problem: What do I do to help these rooted cuttings shoot off new, top growth? Out of the first, 50-odd successfully rooted cuttings, only about half shot up new top growth. The other half just sit there with one leaf, growing longer and longer roots, week after week, and then pft...

What to do?
