Good afternoon! I had my first successful vegetable garden, however, it was at a friends house who had a huge garden, as she moved elsewhere. This year I don’t have that opportunity so my husband is building me a bunch of garden beds and I’m making use of my small backyard. I have a large livestock watering trough (metal) that I was wondering if I could use as one of my vegetable garden beds. I don’t wish to drill holes in it for draining, would that be a problem? Is there a way around doing so?
