hello! I googled this first and the fact that it's not mentioned anywhere on the internet makes me think it's a bad idea, but I thought I'd ask som plant lovers first. I'd really like grow some climbing plants, ivy, vine, creeper, something like that, up one of the bedposts of my bed. They'd get plenty of light, and the bedpost are metal so I'm not worried about rot or anything. But I'm sort of surprised there weren't 4 million people on Pinterest doing this already, so I'm wondering if it is a bad idea or not workable. Thanks!
