Interesting story behind this one!
We quoted on the lawn care for this block of apartments here in Baulkham Hills last year and they did not proceed, other expenses came up.
Next minute this year they email me to say “Houston, we have a problem.” They thought it might be disease or not enough water, whatever!
I replied and said “looks like you have an over zealous helper in the block that is sick of the weeds.” Upon inspection it is obvious to us that the Phantom has been at work with Roundup.
I guess the moral of this story is to take pre-emptive action and warn off all stakeholders from “trying to be helpful”.
Unless you have had experience, best not to get involved!
