First of all have a soil analysis done.

I have no idea what the pictures of your leaves show. Could be caused by many things.

My soil test showed 7#/acre of iron. I posted the results of my analysis here and one response was that my iron was low. Although the foliage on my roses showed no chlorosis I tried some, I forget the name of it, but chelated iron. The rose in question responded. So this Spring I have been adding Iron in the form of Iron oxide. Too early to tell if it will make any difference.

Hopefully someone will recognize your leaves as a symptom of something. It is really tough since there are so many factors involved.

Have you put any fertilizer on them yet?.

Eric, mine look similar, not exactly the same, but I suspected a mineral deficiency of some sort. I took some slightly chlorotic looking leaves to my last Rose Society meeting to show someone. They said my liquid fertilizer should take care of it so we will see.

Dan and Redsox, I added some iron solution and some Miracid type liquid fertilizer (19-5-5). Covering my possible iron/nitrogen deficiency bases.

Earlier in the Spring, I spread some Osmocote. Do you think it's possible it hasn't worked it's way to the roots yet?

Thanks

Eric

I used 10-10-10 earlier in the season, Eric. But I know much less than you do so I will let others weigh in.

It isn't iron chlorosis, because that shows up in the new growth not in the older leaves. For chlorotic older leaves suspect a nitrogen, phosphorus, potassium or magnesium deficiency. I'll bet your miracid will take care of it.

Thanks Maria, I'll keep my eye on it.

And redsox, I wouldn't sell yourself short...I'm still learning a lot myself :)

What is your soil PH?????? If your ph is out of range of 6.3-6.5 Nutrients become more or less available. That is why funny colors show up on the leaves. If the PH was right at 6.3 to 6.5 you would have nice green leaves
