Copper Trellis and Leaching, do you have one?
This is my first post. I have several raised bed organic gardens and am looking at building some copper trellises this year to use in them. On the web I'm seeing a lot of conflicting information about the use of copper due to excessive leaching. However this seems to come down to peoples opinions on the matter and not real world use.
Considering organic gardeners are in general the most picky of what they use around or in their garden I wanted to ask here if anyone is using a copper trellis and if there is any problems with leaching.
I would like to switch to something more long lasting after going through several wooden trellises already. I like the look of copper, especially when considering how it ages.
Any advice or tips would be appreciated.
