Do you suppose all potatoes are treated or do some still just sprout even though treated? Not that I want any additional plants, I just want to try this. I have a bag of Klondike Golddust potatoes. They have a lot of sprouts and perhaps some will waste anyway, so I don't mind using them. Hopefully it wouldn't/won't hurt to wash them off first and then dry just in case. I have a garden staple, and so I pre-reamed a hole in the potato since I read of Angie's woes. The garden staple just happened to be slightly smaller than the stem of the rose. So I still had to somewhat press the rose cutting into the hole. I therefore could see the difficulty unless a hole was first made, and then I don't know how much contact the cutting must have.
Making my hole in the potato:
Stuck cutting and potato placed in a jar and on my counter:
Of course odds may be against because of time of year, and I don't know that window light is sufficient. But it will be fun to see anyway. I may go try a hydrangea and butterfly bush piece just to see what happens.
(I may need to trim up my cutting more.)
