Ludger,
I'm not quite sure were understanding each other. What I mean to say is simply this.... If one grafts a hard to root rothkirch to an easy to root hybrid then one simply cuts a few inches below the graft and roots the easy to root hybrid that the Rothkirch is attached to. What may be different, is the fact that I often leave both parts rooted. In other words, when dealing with Brugmansia I have often left the scion rooted and in its container so it can continue to actively grow to the mother plant. At any rate, rooting an easy to root hybrid is what one is after and grafting Rothkirch to the easy to root hybrid is the easiest way I can think of to get Rothkirch to propagate short of simply air layering it.
Rothkirch
Ludger,
I was just thinking and perhaps this will help, your simply using the easier to root hybrid that your are using as root stock that you can either root by air layering before you make the graft or after you make the graft or you can simply cut a few inches below the portion to be used as the root bearer after the graft is made. Grafting the easier to root hybrid is obviously easy and as Rothkirch grows fine and is difficult to root this would be an easier way to propagate large numbers of Rothkirch, albeit you would have to wait 2 weeks for each graft to take and a few additional weeks for each of the cuttings with grafts attached to them to root after the fact. Still, with a hybrid this hard to propagate...well it might be a way to fill up your green house with rooted Rothkirchs in one season if one had a few large easy to root hybrids and one large Rothkirch.
Eric - Let's say you grafted RK to a Frosty Pink. If you cut it below the graft... wouldn't Frosty branches continue to grow from the roots? Or even from the nodes below the graft?
Thats how I understand it also, poppysue.
Last year, I rooted more Rothkirchs as in years before. Tried a new method and it worked out to be perfect. Just hope, my luck will continue.
Monika, And, what method did you use. It may be good to try on other hard to root brugs. Thanks,
Larry
Poppy, Frosty will come back every time. Same with grafted Roses, always you must take away the wild grow.
Eric, I can follow you, thank you for more explanations.
It the same with Magnolia grandiflora, the new hybrids are all grafted because they dont root.
I have hundreds of seedlings with Rothkirchgenes, I will try to graft some with a Rothkirchsprout.
I prefer to use strong seedlings for grafting because they have a very strong rootsystem and you are shure that you are grafting into growing region and not into flower region.
To be honest: I grafted many plants ( citrushybrids, Cherries, Roses and so on) but never Brugs because there was no need.
AS I said I will try it this spring and summer and I promise you: I will keep you informed, special about Rothkirchgrafting.

Larry, I rooted them in water, thats all. But the right timing to make Rothkirch cuttings is just as important.
You rooted all of your Rothkirchs in just Water??? Well Done Monica but I would never try this. LOL
A little secret: Graft "Difficult-to-Root Plants" to seedlings below their seed leaves. Seedlings have much less chance of Suckering. (And less chance of passing viruses)
The fool proof method: one could allways keep Rothkirch cut close to the soil..this will produce many multi stems, than fill it's pot to the top with more soil and wait for the burried part of all these stems to root! This technique is similar to the one that's used to propagate Heathers...a mound of soil is placed in the middle of the bush and all the stems produce their own roots! It saves allot of space!

Monika:
You said you rooted Rothkirch in water, but making the cuttings at the right time is important.
When and what time to make the cut? Appreciate any help on this if airlayering doesn't work.
The best time is from early summer to end of July, when the mother plant is in growth.
Thank you much. Wrote that down.
