I love rusty and authentic but unfortunately they were making a mess of our new travertine and I was finding their rustiness a little wearing!
I lined the bottom and sides with mesh to stop the soil escaping and used that coconut stuff to insulate them (mental blank - cannot remember the proper name for it!)
The plants are a mix of hardy species which should handle the lack of attention they are sure to get:) I've used pebbles as mulch to complement the travertine.
For the record, on eBay you can buy them for $10 - $15 each....in Sydney at the Murobond store in Artarmon they were selling them for $60 each!!!
It feels good to have gotten one project out of the way:) Thoughts anyone?
