Understood.

I had one that I had to trim frequently to keep it from dropping frags. Then I kept one of the frags, later I had two, and I had to trim them frequently. By the time I had to tear down I had three big ones that I would frag off cycle. A lot of work.

If it's not fragged, it will develop little holes, and those holes will reach out to the outer rim and a pice will drop. When it starts doing that it's not very attractive.

I think yours is one of those. There are others that continue to grow until they are huge.
