Hi Heather – If there were originally ten (10) residents written to by the Strata Manager about removing their potted plants etc, and half of those (including you) haven’t complied, then you could hardly claim that the Strata Manager is forcing only you to comply!
Just do the right thing yourself, and keep in contact with your Strata Manager (who works for you by the way) to make sure that he follows-up to ensure that the other four (4) owners do likewise.
