Do not wait until 2 months AFTER you have planted your garden to put the tomato cages in. If you do it will result in the clusterfuck that you just experienced. Your hands will smell like tomato plant and you will have little green tomatoes strewn about the garden. Also you will have to resort to putting your cages in upside down (although you will convince yourself that they are supposed to be upside down like that) just to get the branches to fit through.
I am sure your neighbours are laughing at you.
