Polymerous, I have wire over them now. But the cockatoos are quite smart and look for ways in. They hit at first light (or when I am having a nap).
They usually sever the seedlings where the roots meet the crown. They are amazingly systematic and move from one to the next tossing them.
The largest plants can survive if they haven't also been shredded. But it is such a loss of energy and growing time for the plants that it will be a long time before they flower.
I am wondering if the brown mulch makes the singularly green seedlings standout for the birds.
The problem is that when you are young your life it is ruined by your parents. When you are older it is ruined by your children.
