Hi,

We are building some large 2x4x2 (w/l/h)ft fixed planters for our balcony. For looks, mahogany seems good. But Don't think it will stand up to the soil contact? Any ideas on how to line the planters, or alternate materials to use, would be appreciated!

I plant to put rotating herb and annual flowers in some of them, and more permanent small "tree" types in some large ones. Any "tree" type plant selection ideas would help too. The site is very windy and very sunny (south facing).

Thanks,

P.K.
