I placed my boxes right on the soil (zone 5 northern Ohio). I used metal screens to prevent the "critters" from gnawing through plastic type screens.

I think that the word "swap" is misleading. Often rose hybridizers have been willing to give pollen, seeds, and or seedlings to other hybridizers without expecting anything in return (sometimes - many times not even postage).

Rosesbydesign, I do not understand your questions. Are you able to read the thesis? My only information is from the thesis. I do not know where the author is now. If the information you desire is not in the thesis, my suggestion is for you to direct them to the thesis director. I should mention that...

Although I did attend the meeting, I do not remember if the spray Forbid was discussed for rose rosette virus control. The minutes of the meeting have not yet been posted. Did anyone remember such a discussion? I am asking because of this recent thread: https://www.houzz.com/discussions/6167847/obse...
