Clematis Wilt? Powdery Mildew? Regardless, this Clematis is getting a very hard prune & then I'm going to spray its soil with an anti-fungal agent. Thank goodness I have it growing in a 1 gallon container to 'trial' it first before planting it in my garden.

Oh my gosh, Shirley. I've never seen anything like that before. I get the virus that causes yellowing leaves, but they don't seem to die easily. I hope it comes out of it for you.

Hi Shirley, waving back at you! Yes I know, it's not a very pretty sight! Hopefully pruning it back hard will re-invigorate this Clematis to grow more healthy vines & leaves. That's why it is so important to 'trial' them before planting in ones garden.

Just yellow leaves without wilting could be caused by a mineral deficiency. I like to occasionally use a fertilizer which contains micro-nutrients. Also, be sure to water your Clematis BEFORE fertilizing, so it doesn't get burned.

Thanks. I'll try to do that soon. I have fertilizer that has micros added, so will do that after our next rain...if we get another one.

What are you using to spray on your dirt?

I am certainly not a clematis expert so please bear with me if I sound stupid. Since the plant is still in a pot could it be that the roots got too hot? The only time I have had one to look like that was when I had it in a pot and failed to shelter the roots from the sun. Mine was fine when I moved it into the shade for a few days and cooled it off.

marie: I'm using a broad based fungicide, either "Bayer Fungus Fighter" or "Scotts Fungus Clear".

patsy: Welcome to the Clematis Forum! Yes, black pots can quickly heat up the root system of plants. However, I have several different varieties of Clematis that I'm growing out in black pots, they should have all then wilted. 'Catherine Clanwilliam' was the ONLY one. The rest are fine.
