I've been working on my backyard and want to incorporate a couple large statement-piece planters. I'm thinking of planting trees in them, or large perennials. Purchasing planters as big as I'm envisioning (at least 2-3 feet tall) is going to cost quite a bit for each planter. And I'd like to make them out of concrete so I figured I could maybe DIY-it.I've found several tutorials on how to do this online. For smaller concrete planters, there are molds. Sometimes people construct molds out of cardboard. For larger ones, you're usually stuck constructing wood templates to act as molds. I want to avoid doing this. With a little creativity, I was hoping to use the concepts behind the tutorials for using molds... but on a larger scale.I want to take two plastic trash cans, one large and one slightly smaller. Add strips of wood across the top of the smaller can to hold it in suspension within the larger can. Grease the concrete-facing sides of both cans with veggie oil to help the concrete not stick (read this on a tutorial). Suspend the smaller one. And then pour in the quikrete and let it cure. (Please see my crude diagram below).Does this seem feasible? Would I need to fill the smaller trash can with dirt or sand to help ensure it doesn't bow in? Do you think I'll be able to reuse the cans? Any ideas and thoughts would be appreciated!https://ift.tt/30YjyJk via /r/DIY https://ift.tt/2ZLP6EQ
