Several years ago, my cat died in January and I had to bury him and it was snowing ....
I knew I had to bury him quite deeply because of the predators we have up here.
Since I garden in rock, I went out and dug up a miniature rose and tossed it in a bucket of water. I knew where a rose was already planted, the soil would be easier to dig in than if I started a new hole. I didn't care if the water in the bucket froze or if the rose died. All I was thinking about was my cat.
At that time, winter night temps were usually in the low 20s to mid-teens so I really did think the water in the bucket would freeze, but it didn't. The rose lived in that bucket for at least four months.
That spring the rose was still alive so I re-planted it in another part of the garden as soon as I could work the soil.
Since the rose was an own root rose, the rose where I had buried Dat Cat came back, so now I have two of that variety. Surprise, surprise.
I had read years ago that Ralph Moore had said, "If there is a way for a rose to survive, the rose will find it."
