Out of about 35 or 40 roses I think there were three or four left. Those are blooming today, and they certainly are doing very well, but there is danger that they will also die as long as they stay there, for whenever a thaw occurs, water is liable to get in. MR. WILSON: How far apart do you set the roses in the bed? MR. KOCH: That depends on the variety; with the Hybrid Perpetuals, usually about two feet, or possibly a little more. I like to have them fairly close together, for the reason that it keeps the ground cool. You spread them too far apart, and you have to work around too much, and I really find the other way better. With the Hybrid Teas, of course, you can plant them about fifteen inches apart; but with the climbers you should have at least a good three feet between them. Otherwise they will take nourishment away from each other, and they will not do quite as well as they should. MRS. STRONG: What time in the fall do you plant roses? MR. KocH: Just as early as I can get the plants. I have been usually able to get them early in October. They make a root growth, and that is just what we want. MR. CHRISTENSON: About pruning; how severely do you prune? Usually most amateurs do not prune severely enough. MR. KocH: I have two or three eyes on each cane, and no more; and if that particular wood is not good and strong and healthy, I cut it down still further. You must remember that pruning is the life of the rose. MR. CHRISTENSON: Do you prune them closely when you set them out? MR. KOCH: I do not believe I pay much attention to the pruning of the plants as I get them from the nursery in the fall. I think I leave them just as they are. I do not remember just what I did before, but I would judge it does not make any differ- ence, because the plants, as you get them from the nursery in the fall are about right, if you buy two or three year old plants. Of course, if you buy very small plants, on their own roots, that is different. I have been a little bit ambitious, and I tried to see what I could do with hybrid tea climbers in this climate. I ordered several hybrid tea climbers which are supposed to be very good, and this particular nurseryman said, "We have not any two-year-old plants, but we are sending you one-year-old plants." When they came-they cost 35 cents apiece, but it was not a question of money,-they were about two or three inches tall, just little slips that had been stuck in sand, and just rooted. Now, you cannot expect much from such plants.
