Wicking beds use a water reservoir below the soil to water the plants above via capillary action. Making the reservoir water-tight can require a bit of effort in folding a sheet of pond liner to cover the base and internal walls of your raised bed. WaterUps® have made this much easier with their new WaterUps® Reservoir Liners – Australian Certified Registered Design No 201915528.
We have made a video to show you how the corners clip together to allow the liner to be freestanding. Check it out.
