Beginner Gardening: Why aren't my roses blooming?, 1 by bethanski

This is the second summer that I have been in my new house; two of the rosebushes are growing rapidly and appear to be flourishing leaf-wise, but have had next to no flowers. I pruned them late last fall and mulched them for the winter, and put rose fertilizer on them as soon as the snow melted for good this spring. Last year the flowers weren't particularly floriferous, but this year they're pathetic! Any ideas?

The picture below is of the larger of the two bushes - I'm not sure what variety they are, but at this point I have seen one bud turn into one flower. The other bush appears to be a grafted rose that is now about half the graft variety and half the root variety, if that could factor into the equation at all, and I've seen two buds bloom of each variety. There are no more buds on either bush.
