Ever since I saw RobBobs YT video of his wicking beds I'd been wanting to build a few, and today we finally got one set up. Several years ago I did a version of this in some old clawfoot bathtubs I have in the backyard, with incredible results, however the plug I used to seal up the bottom drain eventually gave out on both and I've cleverly avoided digging them both out by pretending nothing is wrong with either one. The design is simple enough. Take a container, build a water reservoir in it, run media down into it, put in a drain hole somewhere so it doesn't get too full of water, and get to planting. For those of us in arid (well not this year, but anyway) regions it's a way to keep the water restricted to what you want to grow with minimal evaporation. It also stymies the wire grass. This is the top 1/3d off an IBC tote. The 4" perforated drain pipe will serve as a water conduit as well as reservoir. Leaving a well in the center for the wicking sand. I used zip ties and a piece of landscape fabric over the end to help keep gravel and whatnot out of this end of the pipe. Filled the outer perimeter with pea gravel which will provide support for the upper layers while allowing the water through. I would have preferred a larger rock but we have a trailer load of pea gravel so that's what I used. You can see our drain hole there in the right hand corner about an inch above the gravel. I realized that was a bit high after the fact so we tapped another one about an inch lower. Over this goes landscape fabric, which will allow water to pass through but keep the sand from filtering all down through the gravel. Next comes the sand. A nearby sand and gravel place let me have sand for $1 per 5 gallon bucket, which beat the $7 and change a bag that Wallyworld wanted for playsand and $3.something a bag at Home Depot, and beat the hell out of me digging it up at the nearest riverbed. The sand pushes down into the well in the center and rises about 3-4 inches above the gravel layer. Next comes a layer of mulch about 4-6 inches thick. You don't want to put dirt on the sand because it will stay wet and you'll get all kinds of ick in there as it can create an anaerobic space. The mulch will eventually degrade down but it won't have the same issues as soil will in that spot. And finally comes the dirt, which fills the bed to the top for now. This will settle down a lot over the winter but that's ok because I'll add lots of rabbit poo to the top of this as it sinks. By spring this will be ready to plant. Once the plants are established I can water through the drain pipe that sticks up. I'll go back later tonight and strap some mesh over that so the frogs and critters stay out, and maybe set a couple of rabbit cages over it so they can get to work adding poo, but for now that's one project down. And here's the video that got me on this.
