I think I might have posted this message somewhere on DG but cant' find it so I'll try again. I have a problem with the leaves of all the columbines. They are all in full bloom but all the leaves are blotchy, hardly any green to them, kind of whitish. I understand from an internet search that columbines are very susceptable to powdery mildew. I just went out to feel the leaves but the dew is still on them and they are wet still. Could it be all the rain we have had lately? One weekend it was 3 in. total rainfall. I have some Bayer product that says it is good for powderly mildew and other diseases. I can make up a solution using baking soda and spray. I don't have any horticultural oil to add to that solution and don't want to go out and buy it either because I have so many products already here that I haven't used a lot after I bought them. You only have so much storage space.
Any suggestions or recommendations for this problem. I first thought it might be because I had sprayed with Liquid Fence after seeing the deer walking around one night.
