What's the Secret Garden Competition, Cameron?
I have very little knowledge about it, from what i gather, garden, that aren't allways seen, (in this case the school garden), that are opened for one month allowing people to come and go, a group of Judges comes around all the gardens, and a winner is announced at the end.
It was our leading teacher that arranged it, all we (pupils) do is grow things, pick things, and sell the end product. I even have "school" hens , they live with me for most of the year and at holidays, but any eggs layed are given to Home Economics.
Hope this helps a little
