Variegation - virus, mineral deficiency or other

First thread. I came across this in unrelated plants planted next to each other in a raised bed. There is a lot of bark chips around, the soil is the usual london clay found in North Surrey close to London. A rose, a clematis and a jasmine all showing marked variegation. Any ideas please?

 

Welcome to Gardeners Corner Czechmate. I'm sorry, it isn't variegation, it looks like Mosaic virus which can spread from one plant to another not just roses.

Thanks for the reply. The reason I suspect that it can't be RMV is the effects on wholely unrelated plants right next to it. Virus usually affects groups of closely related plants. Roses - Prunus and Apples not Clematis or Jasmine and various pages describe these diseases as hardly even infectious among planted roses, certainly not across genus. RMV is described as reducing vigour in the individual plant but not affecting others.... the only thing in that bed that hasn't been affected are the bluebells! (which are Spanish and can die now please)

 

Mosaic Virus doesn't just affect roses it affects many other species of plants too and can be passed on by handling one plant then another.

 

Mosaic Virus is not one but many viruses and seem to not be transgenic. I find it unlikely that one species of Virus like this would infect three unrelated plants. An article written by a plant pathologist suggest the only proven method of transmition is in propagation. I am unable to post a link for some reason.

 

I'm sorry Czechmate but botanists and scientists aren't always correct in their theories. I believe your plants have Mosaic virus and I'm 100% certain it's not variegation but I think we both agree there is something very wrong with the health of your plants. Perhaps other members may be able to help you.

You may not be able to post links until you have made a certain number of posts.

 

Hi

Looks like they have been sprayed with something and it has effected the leaves , it reminds me of a time in one of my other houses I lived in and the guy next door sprayed his apple trees with a winter tar wash and as it was windy ended up in my garden and all my shrubs leaves looked similar .

Nothing to do with variegation

mosaic viruses This virus infects more than 150 types of plants, including many fruits, vegetables, and flowers. It is characterized by leaves mottled with yellow, white, and light and dark green spots or streaks. Some of the most commonly infected plants include tomatoes, potatoes, squash, and cucumbers & roses.
