Raised bed question

[jbett98]

I would scronge up some Tyvek house wrap and use that inside the box.
It's micro pore breathable fabric would keep the soil from contacting the wood along with it's wood destroying organisms, but allow the moisture to wick away. A double wrap should work and the Tyvek is inherently stable with no chemical leaching.

Flowers? Anything will do for flowers but veggies? Anything you use can go in the food. Better to rebuild everything five years.

Either redwood or cedar will last quite awhile. On The Ground, my choice would be masonry of some sort. Bricks, blocks whatever.

Nice work !

I'd dig a 3" deep trench the size if the box, line that with black plastic with drain holes then build a 2 x 4 treated frame on top and place the box on that. The frame would keep the box off the ground; keep moisture away from the box bottom and keep the box "dry." I assume you will line the box interior with heavy plastic.

This is what you need. Put a couple of coats on the interior surface of the wood and it will be a permanent, no leak solution. Once cured, epoxy is completely inert so it won't contaminate anything in your planter. This is what people use to build boats. Don't use it on the exterior of the box because epoxy isn't UV resistant and will yellow in direct sunlight.

Those look great, but anything you put in there will leach it's chemicals so if you looking for a food garden I wouldn't use anything I would eat.
