Garden Bed Depth

That's what I figured Fu . Well, now you know why I'll be using pebbles

Oh Fu, you're a kack
Now that I have your blessing .......my life is in harmony

That's cute ... looks like a pet , little green hairy dog ...

Anyway, found this, but not sure if it's true:
Bromeliads are native Latin American plants that require very little soil to grow well.

From memory (saw this in another thread) you have rock under this thin bed? I am guessing here, but if you are really desperate for some foliage there, I would try growing something, just one plant as a test. If you have rock down under, I suppose all water would just distribute and soak the soil horizontally, so if that theory is correct, the plants shouldn't suffer too much. And tehre are all those various feeds and conditioners etc., as Fu always reminds us of - they should help keep it alive

Hahaha, fair enough !! I can sooooo understand when someone is fixed on having to have something ... so I had to try !! (well, except for destroying that rock )
