I have 2 dwarf pampas planted in whiskey barrels that are 3 years old and HAVE bloomed last year. I don't remember when they started showing green last year but they haven't shown a thing so far this year. Am I being impatient? Also, they get overspray from the pasture irrigation and I see black spots in the stems (cut back), is this a type of mold? Are they gonners? I was thinking about digging them up to divide them if they are still alive....shouldn't I be able to tell that from the roots?
