I live in zone 6 and we have had a very wet spring. The bush gets between 5
to 6 hours of sun a day. It started off great with tons of blooms, but one
by one as the blooms have been opening some of the leaves on the canes have
been yellowing.

The rose gets fed with one of those weed and feed combo mixes and has not
recently been pruned.

Weed and feed? As in for lawns? With the herbicide 2-4-D in it? The one
that kills broad leaf plants?

Do you mean something else, like an all-in-one rose product?
