That is very interesting. Keep us posted on the results.

You do know that you will be growing Potato plants with your roses don't you unless you peeled off all of the eyes. I used worm castings that I had from feeding worms in a worm bin leftovers once and ended up with a bunch of tomato plants along with the roses. Be careful what you wish for.

Several people tried this over on the propagation forum a couple of years ago and ended up with rotted cuttings and rotted potatoes. I hope it works better for you.

Well, I for one am really curious to hear how this experient works out. Having lived in west Texas before, and knowing how hard it is to keep young plants well hydrated in the winds, I think there might be some merit to the potato method. I had heard of doing this slightly differently though:

The old method I have read of but never tried, instructs you to cut a wedge of potato (it didnt mention the eyes, but removing them sounds smart), and slice about halfway through it as if you were going to cut it up into chunks. Slip your rose cutting in to this slice, seating the rose cutting well into the potato body. Water it well, and plant it into a pot of good soil. Allow the soil to dry out between waterings, so the potato won't rot.

did any of ya'll ever try it?

My neighbor from Hungary said people had success using potatoes for starting roses back when his family lived there during WWII. They moved here after the war to escape the Russian soldiers. But he said it did work for them.
