A few months back I wanted a shrub to put in an empty space in my garden.I didn't know what I wanted so I chose a Pink Bottle Brush I must admit in a hurry.When I read the tag at home it said don't plant near a path or pipes.I didn't know then what to do with it. It was going to head towards some pipes or my septic tank.I had a fairly large empty ceramic pot on my deck and I put it in that.It is growing really well and now I think it may not be long before it gets root bound.My question is - if it becomes root bound can it live forever in that pot if I keep watering and feeding it?
