Also, the leaves seem to curl and there are some strange looking edges. Perhaps the photos will clarify what I am trying to describe above. Please be so kind to look at them. The rose is Paul's Scarlet Climber, by the way. I am hoping that some of you might know what I am missing here. Do I need to feed my rose something in particular or is there some kind of disease playing house in and on my rose? Awaiting your kind replies, Eric Attachments: Quote \| Reply \| Report

Thrips of Midges are possibilities. Are there any bugs or small maggots on the leaves or flowers? Those can be treated with sprays. OR it could be a potassium deficiency. Have you soil tested (at your local university extention, or get a soil tester at the garden center.) If it shows your soil is too acidic, apply lime. If soil PH is ok, the feed with potassium nitrate. Hope this helps PS. I just saw your blueberry post....where is that in relation to your rose??? sass Quote \| Reply \| Report

I was thinking more in the direction of magnesium, since the potassium is present in the fertilizer. Quote: Originally posted by sassmuffin Have you soil tested ...

My other guess would then be a copper deficiency, that presents as wilted leaves with no yellowing. If it were my rose, I would try 1/4 teaspoon of copper sulfate, and a 1/2 cup of epsom salts. Just to cover both bases. Quote \| Reply \| Report
