I definitely don't have that problem. I purge in the fall of the third year or really early in the forth spring. Good plants may be crowded, but by then, they are either being conposted or moved to the keeper bed or a permanent bed. Clearly I don't treat mine as well as you do, Dennis. I would say, often you can see in the 2nd year that the plant isnt a keeper. You know, poor habit, really short scapes, "great personality". So you could purge some in the second fall to make more space. Just a thought.
