oh! it just came to me..
you mean the green chicken wire in the pots!
I explained what its for in the page! right next to the photos!
No, it does nothing to hold up the plants..and the sarrs dont really need holding up anyway..I had some trouble with birds again, so I hung up the CDs again..
it worked ok, but there was one particulary tenacious mother robin building a new nest,
she kept robbing bits of the moss every day, tearing out plants in the process,
and the CDs didnt work on her! so I had to also add some green chicken wire over the pots! I didnt care for the look, but by summer the plants had grown right through the wire and you hardly noticed it.
(except for a few really tall ones every year that get blown over by wind)
its only to keep birds from digging in, and stealing the moss.
