White stuff on leaves..pics included..
I finally have figured out my camera so I have taken pics of everything going wrong It will take a few different posts to cover it all!...It is a white substance on leaves (don't know if it is powdery or sticky as I didn't want to touch it..even with gloves!) I noticed it 2 days ago..The single leave is from a rudbeckia, that is in full bloom and seems very healthy. It was planted 2 months ago.
I've never uploaded a pic before so I'll only do one at a time...However, this or a similar substance is also on a rose bush and I will post that pic later..
I did a search and have found this could be a couple of different things from virus, aphids, mildew..etc..so any help, suggestions or advice is greatly appreciated...
