Rose disease?

My rosebush was a gift to Grandma 40 years ago. We saved it when her house got knocked down, for the last two years it's been living in a large pot. It was Climbing Peace I think.
This season, it has a new thing wrong with it. Looking on the web it seems like Rose Mosaic disease, yet it never had this before so I am confused. (since it cannot be spread/is not contagious it could not just get it now).

Iron iron deficiency?
It does not appear on the new growth, I would like to upload pics so you can help me. Seems silly but would like to save this bush vs. buying a replacement. It was the first plant I ever bought my grandma as a gift.

I am not sure where to upload a picture of the rose leaves?

Rags, Check the link below for a host of images of Rose Mosaic Virus.

If your rose was purchased 40 years ago, it is almost certainly virused. Never fear! So is the rose my mother transplanted from HER mother's garden, to hers. Some day, when my mother's home is to be sold, we'll dig 'er up and transplant her to my home, or my sister's.

The virus in your plant PROBABLY showed itself now because of the stress of the move. The bad news is that you can't cure the disease. The good news is that there is little chance of it spreading to other plants.

tyvm Jeri for the helpful reply. Its more beige, and skeleton like then most of the pics show.the leaves are transparent-ish on the effected spots. Which I could upload a pic. It's been in a pot for some time now, and did well for the last two summers.

From your description of beige and skeletonized, I am thinking rose slugs, they are little green inchworm looking things on the underside of leaves. Take a look for them, doesn't sound like mosaic virus to me.

I agree with T-bred.

Look on the UNDERSIDE of the leaves, for those teeny green worms. Squish them! They pop rather satisfactorily. :-)

If what you are seeing is brown patches on the leaves, which are dried, I am seeing the same thing. I just checked Baldo Villegas' site, and concluded rose slugs, actually sawfly larvae, must be the cause. This seems to be a bad year for the sawflies in NY.

If it is RMV and not slugs it probably had it all along and only just now showed symptoms. That's very common with RMV. For a long time during the mid 20th century most all roses were grafted to infected root stock. So most of those roses have RMV. It does not mean a death sentence for your rose however. RMVed roses can live a very long time and give you lots of beautiful blooms.

If it's rose slugs you can decide if you want to spray it with an insecticide or not. Always ID the insect you have first and then find the proper insecticide for that insect though. Otherwise, I'm not positive but I think they have a season like most insects and will eventually disappear on their own.

Is there any chance that you can plant this rose in the ground? Roses like being planted in the ground best. If not what size pot do you have it in? For a climbing Peace you need a VERY BIG pot! Something a good 2 feet deep and wide at least or bigger if you can find one. You need to put extra drainage holes in the pots too. You want to put it up on something (bricks or blocks of wood) so it can drain freely. And always use potting soil NOT garden soil or dirt from you garden. Potting soil is lighter and will drain properly. Those others are heavy and will hold too much moisture. I know it sounds counter productive to make sure your drainage is so good because roses like a lot of water. But they like damp soil that the water drains through and hate to have their roots sitting in a pool of it.

To post a picture, if you have an online photo site like Photobucket you can post pictures by copying the httm address there and pasting it into your post here. You can also post a picture from your computer now by following the instructions that come up at the bottom of the page after you hit "Preview Message".

I'm glad you saved Grandma's rose. It will always bring you fond memories. Enjoy!
