IF there is no rush, that is if the lot will remain undisturbed for a few months, the most dependable way to get starts of these shrubs is to layer the rose and take a spade and jam down into the roots of the crape myrtle. The rose branch should root, and the crape myrtle should put up a root sprout where the root is damaged. Then in the fall you can move them. This is the way I have successfully propagated this shrubs.

IF time is a concern you can take cuttings of new wood of each and dip the cut ends into rooting hormone and stick them into a pot of moist potting mix. Make a tent of a plastic bag with a couple of small slits in it and hope for the best.

Thanks for the advice but I don't understand what you mean by layer the rose.
I can do that to the crape with the spade and then take cuttings I have some rotone that I use to propergate my mothers toungs damaged leaves.
so should I take cuttings now?

Thanks for the advice!

layering is done a couple different ways. below is a good place to start researching how to do different types.

Great Link MK. Thanks for that. Tree, if the rose is a grafted variety, layering may not be as succesful as these do not always layer well. That's why the instructions say climbing roses which are more often grown on their own roots. If you have the time why not try both methods. And yes, now would be a good time to take cuttings. If they don't take you could try again in a month.
