I rarely need to thow anything out
but once in a while:-
I throw out a few potatoes that have turned green
Carrots that go black-spotty or soft
and sometimes a cucumber has got too cold in the fridge
~so that ends up in the compost~
same has happened with the odd luttuce
I will often freeze bread and pop slices straight into the toaster
the birds get well fed here daily~as I make sure I buy their assorted foods
Birds enjoy lots of foods and fruit that most people throw away
[NEVER give them dessicated coconut ~or dried rice ]
I recently found out that if you crush all your egg shells
~ and add it to their foods~
it helps them and their young to get much needed calcium into their diet
