    The leaves towards the top looks normal .mostly its the bottom leaves . now I am scared of planting them in the ground .

    Is there a reason why you're watering daily?

  • 10 years ago

    Have you turned the affected leaves over? Do they have bright orange spots on them? If so, it might be rust. Can't tell from only looking at the tops.

    Watering a new rose daily is probably to much. It kind of looks like salt fertilizer burn. Maybe someone at the nursery dumped to much fertilizer in the pot. There are mosaic viruses that can look like the top leaf set but as they are getting older they are turning yellow and ready to fall off.

    Commercial nurseries usually water at least once a day, so I don't think that you are over watering, especially not in Florida . The effected leaves do not look like rose mosaic virus, The problem could be a past stress, or past deficiency or just old age. The new leaves look good and that is what is important. I'd plant them out. In Florida rust is not a problem, I'm in Florida too,

    Dr Malcolm Manners at Southern College in Lakeland, Florida is really the expert on rose mosaic, he has done experiments to prove that it can't move from plant to plant. The rosette virus that has everyone so worried, is supposedly not a problem here either, we don't have the insect that spreads it. I still going be careful with bringing in new roses from outside Florida just in case the experts are wrong about rosette virus. I'll keep them in isolation for a week or two before they go out in the garden.

    They came by UPS 2 day service .l suppose there were a couple of yellow leaves when they arrived 3 days ago but now there are many .l was watering them daily because they appeared dry when l got them out .and temperature here has been in the 90 's in the last days .

    I'm so sorry to say this but rose rosette has been confirmed in Florida. Check with your university sires to confirm.

    Patty ,earlier this year l bought 2 bodybag roses from Home Depot locally and planted them .l think they were contaminated with RRD.because one grew thorny red stems and distorted red leaves .it was so unusual that l searched it up and suspected RRD .and removed it completely .the other rose bush was starting to thicken and get thorny so l removed it too to be careful because it was too close .

    I didn't plant anything in the holes .

    I'm sorry pink rose I did not know that they were mail ordered. Yellowing of leaves happens sometimes when they climb in those boxes. With your heat so high already, have you thought about potting them up so that they can grow stronger. Then plant out in fall. Daily water is fine in that kind of heat. With it that hot do give them shade or bright light until they adjust. That black pot will sear the roots of your rose in hot sunlight.

    Thanks Patty .you dont think its a virus ? Only stressed out plants ?

  • 10 years ago

    Thanks for the warning pink rose. It's a shame that you could not have posted photos of them. I'll have to go to read this one. There was a post from a reputable site that said rrd had shown up at a nursery.

  • 10 years ago

    Whoops, I'm one post behind you. I do think it's stress but that does not mean I right. However could I ask what variety of rose it is.

    The reason I don't think it to be a virus is that the leaves have continued to yellow. Here is a site with some nice photos. Rose Mosaic Virus - New Mexico State University

    Have you checked the undersides of your leaves? Check for orangey spots also check for webbing and what looks like specks of dirt.

  • 10 years ago

    Hi Patty ,

    I looked under the roses , nothing there . maybe some webbing between some leaves which indicates spider mites. I tried washing the leaves , but it appears some of them may have some of the potted soil stuck .

  • 10 years ago

    maybe that whats causing the leaves to yellow ?

  • 10 years ago

    I would just take off the offending leaves - the rest of them look very healthy.

    Jackie

  • 10 years ago

    I will just do that !

  • 10 years ago

    That sounds good and that leaf does look like spider mites. Spray water on the other leaves daily since it's so hot or they will climb on those next. Good luck with your pretty roses.

    Thanks patty !

    Hi Patty. I meant that rosette virus has not been a problem on Roses grown in Florida, only those that come in from other states. As far as I can tell, it has only shown up on a few Knockouts brought into Florida. We lack both the insect to spread and, the wild roses to host it. I realize that

    this could change and we should be cautious about bringing new roses from unknown sources in to our gardens.

    Hi Patty, interesting info.

    The roses that exists in the wild in Florida are few and scattered. I don't see how the rosette virus can "jump" from wild rose to wild rose to invade Florida. As long as we don't have the mite or fields of wild roses, we remain relatively safe.

    To keep the virus from becoming an epidemic in Florida, we need to be aware of its symptoms, be careful of the roses that we buy, and remove plants that show symptoms.

    I would chalk it up to shipping stress and just remove those leaves. Also K&M potting soil is very thin (for shipping), so I would repot it if you are not going to plant it soon.

    Thanks ,I will.
