Clematis leaves drying
Hi, I've got a group 2 clematis, multi-blue, 3-4 years old, growing at the inside space of my arbor. At the outside space there is a Quadra rose, which I planted this year. Here is a photo of it, in flowers this year:
Each year after it's spring flowering, it's lower leaves turn yellowish, here is a photo of the leaves as of today:
This year it has been particularly bad, the plant looks half dead at the bottom,
However, as you can see, the top branches, which I trimmed in June are sprouting out new, healthy shoots now.
We had a lot of rain this spring, especially in July. A little less in August. The roots are completely in shade and there is some compost/mulch at it's feet.
Is this pattern normal, or I'm doing something very wrong?
