Well, are you feeding them? Roses are very hungry plants and like to be fed lots. Mine usually get blood.. from my legs. LOLLL no, seriously though, they *are* heavy feeders. Can you post pictures? A lot can be determined by looking at the leaves. Also, what zone are you in? And losing only 7 roses is a miracle.. I wish I lost only 7 roses this winter. I think I lost probably closer to 40-50 roses.
