Question
I inherited a number of different roses with the house. Don't know what kind they are, but the first couple of years, we had beautiful roses all summer long. The last couple, the roses still put out many buds, but they tend to turn brown and die before they bloom, the ones that bloom either die quickly, or the darker color petals look like they have been splashed with bleach. I don't know what to do.
