This particular Climber that I referred to had about five or six canes, some fifteen or eighteen feet long. One of the best canes had some moisture get in about half way up the length of the cane, and I had to cut it off. The balance of that cane, instead of flowering, began to throw out new shoots, which of course do not flower, because climbers flower, with one or two exceptions, on the previous year's growth. Now, if you should have that same experience, cut it off, because you will have just so many more flowers on the other canes that remain, if you do. There were three other canes, as I recall it, on this rose of mine. I counted the flowers on one of them. I stopped at 125. Every one of them was a nice, fine looking flower, probably three or four or five inches across when fully expanded. I do not know where you could find anything better than that for out-of-doors. That was the result of covering the climbers during the winter. Be- fore that I took some of the advice of the rose books, which said that this climber was perfectly hardy. That is not so. It is not hardy in Wisconsin. It is hardy only to a certain extent. I was told the other night that in Europe, where the climate is much warmer than here, the practice is made of covering roses with soil throughout the winter. Why should we not do it here, where they have to stand just so much more? Now, about uncovering.. That is something you will have to learn. You have to uncover them just at the right time. If you uncover them too early, they are apt to be injured by late frosts on the new growth. If you do not uncover them early enough the roses-especially the climbing roses-will throw out new shoots, which make large flowers; and if the snow then gets at them, of course they dry up. So you have to find a happy medium, and uncover them just at the right time. I usually find it best to uncover them a little early, and take a chance on the weather. For that reason I leave the climbers on the ground for a day or two, or a week, if necessary. And if by some chance we should have a real heavy frost that might injure the plants, or the new growth, I have some handy material there that I just simply throw over the plants in the evening before I retire. In that way I brought through about twenty climbers, I think, this year, and probably six or seven perpetuals. The beauty of the climbers is that some of them start early, and the last of them
