Now, that is real pond liner and not the poly you find at Home Depot. This stuff is extremely hard to shape in place. My hat is off to Jeremy. And thanks for showing us how to do a corner. That is the most difficulty part of the whole project.
Will this liner help keep the tree roots from invading the raised bed ? I have tall redwood and maple trees within 25' of my raised bed and the raised bed gets invaded by roots in no time. How thick is this liner ?
Hi Matt, the primary purpose is to create a sealed water reservoir, so you can irrigate from the bottom up (using capillary/wicking action), rather than the top down. You can read more here: www.wickingbeds.com.au/ Best, J@VEG
