Having read with much interest the notes of your correspondents in regard to the disease (?); which has made its appearance on the Marechal Niel Rose of fate, and having had personal experience with it, will relate it and my remedy as a cure. We have a Marechal Niel worked on the Dog Rose. It is about four years old. It has grown finely and bloomed very well all along until last Fall, when we cut it back to throw blooms for Christmas. It attracted our attention by being very slow breaking; but we judged the cloudy weather as the cause of that. But at length it did break, and bloomed about five or six dozen blooms. Some of the blooms were medium good, others were not. After it finished blooming, our rose began to turn back, dropped its leaves, showed no inclination whatever to break. We concluded our rose must have the same disease (?) your correspondents described in the Monthly. We examined it and found it exactly so, namely, with a large shapeless excrescence just above the union, and also numerous very small ones at intervals along the stem, like warts. Our proprietor informed me that it was " going to die, and I might try any experiment I wished." 1 began work by cutting all the small excrescence off" close, and about one-third of the large ones also.
I then washed the wounds well with strong sulphur water, and rubbed sulphur well in the wounds, and wet some sulphur, adding water enough to make it stick; then gave all of the wounds a good coat of it, let it remain two weeks or so, when I found it began slightly to heal. I gave it another washing, and treated it the same as before, and let it remain for two weeks more, when it had healed nearly over. I made two more cuttings of the large excrescence, and treated it in the same way as described, and in course of time it healed completely over again. I found the excrescence inside to be of a very brittlely nature, having rusted dead streaks through it. My rose did not make any headway for a while; but as time wore on it began to break, increasing more vigorously as the weather began to get fine, and now, May 5th, you could not wish to see a more healthy plant. It has " set" more than one hundred buds, and is continuing to bud.
I somewhat agree with W. W. as regards the cause of the disease, for it plainly illustrates his statement; whereas it prefers to break just above the union. In conclusion, I might say I have found the Marechal Niel more sensitive and impatient of any neglect than any rose I have met with, though when properly cared for it will amply repay any extra trouble the operator may have had.
