Just got this yellow rose bush tree for free! ($25.00 value) They said it was dead, but you can see green stems on it. I have it in miracle grow potting soil and I fed it some miracle grow rose food. Its in the amount of sun it needs. As you can see my rose bush next to it is just fine.
My question is, do I need to cut all this dead limb off to the green limb or just leave it the way it is?
