White Out rosebush lost all petals
I planted a White Out Rose back in April. It did well and was full of blooms within about 6 weeks. We went on vacation for 5 days, during which temperatures here were in the low 80s with some rain. When we got home I noticed that every rose has lost its petals. I am wondering a) what happened and b) what I can do now. Should I deadhead what is there? I am a novice garder so I appreciate any advice.
