Help!!!!!
My 4 week old bare root rose bush is getting black at the top of several of the original cuts. New leaves are still coming in but it looks like it is trying to die from the top down. Do I have root rot or crown gall? I live in Arizona and the bush is planted in partial shade (afternoons). __________________________________________________ ________________ Darlene Bachman-Calkins ICQ#: 3266702 Current ICQ status: + More ways to contact me __________________________________________________ ________________ |

Hmmm. Is this when Arizonans plant bare roots? Some questions: how did you plant this rose, where did it come from, and how have you treated it since you put it in the ground? |

I followed the instructions on the package. 2 foot deep and round hole mound
of bone meal treated dirt with roots around it. Filled and watered with B-1 for 10 days. Then water once a week since. I got the bush at Home Depot it was one of the premium bushes but I do not know which one. After re-watering it yesterday with a tablespoon or so of the B-1 the leaves have perked up. I cannot see if the black on the cut ends of part of the bush are any worse or not. "Shiva" wrote in message news:aHlwYXRpYQ==.eb43ce5e446761a59f6192f912e7a778 @1043677824.cotse.net...

You must cut off all of the black stuff ASAP, 1/2 inch below the lowest appearance of the black stuff, if you want to save the rose. If the black reaches the bud union, your rose is toast. You MUST sterilize your pruners after every cut. Use a bucket with 4 cups of water and 1 cup of Clorox to dip the pruner blades in for 10 seconds after every cut. Dispose of the cut canes in the garbage quickly and don't let them touch any part of the plant. Be careful not to touch the ends of the cuts with anything that has touched the canker, such as your hand or glove as well. If it re appears, do it again.

Most often it's because the rose has not been properly re-hydrated before planting. It doesn't sound as if you soaked the plant before putting it in the ground. I'd cut the black part of those canes off before it spreads. Cut at least a quarter to half an inch below where the end of the black stops, even if that means you're cutting off some new foliage. If you don't, the cane will definitely continue to die back. Keep an eye on it and don't let the dieback spread. |
