Cheryl,
Old roses (antique or own-root roses, not grafted hybrid teas) don't require a lot of fertilizer, especially in our climate. If there is a lot of new, tender growth, our July-September heat can damage or kill the new growth. Also, trying to promote bloom when the plant is heat-stressed or going through a dry period can really set a rose bush back.
I fertilize mine at planting, then in April when they are in bloom, and again in late August to give them a boost for the fall flush of flowers. The roses bloom intermittently throughout the summer, but I don't encourage them other than seeing that they get enough water.
I use composted cow manure, but that's just because there's a lot of it laying around in the next field (and I'm cheap!).
