Please post images.

Here are some pix taken today & a few last year to compare.

Thanks for asking Jean001a! Tia for your thoughts!

Here is a link that might be useful: Eye balling Clematis problem

Page not found.

Chlorosis due to iron or magnesium deficiency does leave the veins green and the rest of the leaf yellow or pale. Worse on the new growth.

I wonder why album won't open ~ I copied title & pasted as I used to w/o problems.
Let's see if it opens this time?

That link works.
Looks like a severe chlorosis to me.
Virus infected leaves look more mottled.

Thank you ~ I feel so much better!!! How often may I treat w/ the iron/magnisium solution.

We've been getting an awful lot of rain ~ not daily but heavy when we do. I wonder if the treatment I've given could have washed out some!

TIA again for you thoughts!!!

Looks more virusy to me but I'm no expert. Heavy rain can wash away nutrients.

I would apply a shot of Mir-Acid, Miracle Gro acid fertilizer in the blue box and if it greens up, it is chlorosis. If not....

As I posted on the *Virus* thread :I started looking for photos of Clems affected by viruses & found a few w/ accompanying description of how the particular affected Clem behaves. I feel a bit reassured that the pattern of yellowing on my 3 Clems are more like *Chlorosis* than *Virus*. W/ fingers crossed & prayers I hope they'll be OK w/ chelated iron treatments!

I just posted again on my original 'Virus' post and I'll post here also. The pattern of yellowing on your plants is different than on mine. On yours the yellow is between the veins, on mine (virused), the yellowing was in the veins. Also, my sick plants have no leaves which are completely yellow as I saw in your pics. Hoope this helps.

Thank you for taking the time to view my posted pix & your reassuring observations, Chrisstine!!!

My 3 yellowing Clemmies seem to be improving after 2nd dose of *Chelated Iron* Rx!!! W/ fingers X'd hope they continue to get better!!!

FWIW!

How often may I treat chlorotic Clemies w/ *Chelated Iron* w/o hurting them, since they seem to be responding some to the past 2 treatments?

Would very much appreciate your thoughts & experiences!!!

Tia!
