Been thinking.

       It/they have been a bit neglected the last year or three.  This one showed face (DAMN auto correct) last year, as a first and; I vowed to separate it, and didn't.
      There's always a "however"; this year I see the largest "half" comprises two of these.  The smaller half only has two "Bog Standard" Reds.  I also see that it has a long group of "Leaves"/ sections; so I might try another, taller Tree.  Two possible reason, if not three.
   1. It got top heavy last year, fell and lost half its splendour.
   2. It's now so big/long that it hangs below the Pot Bottom; you may/may not see it dependent upon shots take.
   OOOOPS! got distracted = forgot #3.
