Knockout Roses are rose bushes that grow 4 feet tall and wide. In the spring, you cut them back to 18" and they grow to 4 feet again. Last year I accidentally cut the tops of two Azaleas that bloom big red every year and I was worried I messed them up. To my surprise they actually did a quick vegetation grow then bloomed REAL big red like the cut back actually helped. I know with the Knockout Roses you are supposed to cut them back in early Spring. Question, are Azaleas supposed to be cut back similar to Knockout Roses? Maybe not cutback as hard but cutback at all? Early Spring??
