FIFTY-FIRST ANNUAL REPORT OF Whereas, with own root stock, all you need to do is to make the cutting, stick it in sand, be a little careful of it, and in a week or two you have roots. Then put them in your hothouse, and in another year you have the so-called two-year plant. That is one of the main reasons why they advertise own root stock as they do. There is no question about it. - As far as the flowers themselves are concerned you will find that on own root stock you will get one or two flowers. The plant will throw probably three or four more buds, but the first thing you know, you have bud rot. They do not mature. That is undoubtedly due to the fact that there is not sufficient nourish- ment there to mature the flowers; whereas, with budded stock, I have had twenty-five and thirty flowers, every one maturing; some that were full size, and almost perfect, I might say, for outdoor rose growing. Now, that to me is pretty clear evidence. You cannot get away from it. It stands to reason that the bud- ded stock is the thing, especially when all of the amateur growers -I am not speaking of any professionals-tell you the same thing. Wherever they possibly can, they will buy only budded stock. Of course, there are exceptions. Some of the more vigorous growing kinds will do fairly well on own roots after some years, but that means a wait of three or four years. I have two plants of a particular rose, Hybrid Tea, one on budded stock, and the other which I raised from a one-year cutting, bought from an Eastern nursery. It would do your heart good to see the flowers on the budded plant, and when you compare them with the flowers on the own root plant, the comparison is most impressive. If you took the own root plant by itself, you might think it was very fine, because it would be really good in a way; but it would be nothing as compared to the flowers on the budded stock. Now, the next thing of importance that I have found is the problem of how to winter roses in Wisconsin. You all know that our climate is severe, and during January we usually have the so-called January thaw. That is something that must be guarded against, because if moisture gets on the roses during the winter months, it is apt to be fatal to them. I have developed a plan. The suggestions concerning this plan were given to me by another grower, also an amateur. Toward the end of a season I stop cultivating, so as to discourage all new growths. This will ripen the wood. The riper you can get the wood, the
