1. What in the heck is "aesthetically exposed liner"?
AND
2. Actually no it's not. And you saying it is doesn't make it true. I communicated clearly and succinctly that I disagreed with you. It's the disagreement you don't like, not the style.
Back to #1 - there is literally NOTHING "aesthetic" about exposed liner above the water level. Maybe you mean "accidental" or "unintentional" - both of which happen. We have had LOTS of new pond owners come to ask for help with a pond they built where they did not build the edge correctly and the liner is constantly showing. We share tips and tricks to camouflage the mistake but ultimately suggest they re-do it. Many do so; some can't or choose not to. Either way, the information is the same. Facts don't change to accommodate feelings. This poster said he/she wanted to learn - I think common courtesy would require that I give accurate information. Which I did and will continue to do, unapologetically.
And this is indeed a social forum, but it's also an extremely powerful tool. Every conversation you have with every poster is preserved and will be a conversation you have with countless pond people in the future who come looking for accurate and helpful information. We don't all agree here about every detail on how to build, keep, manage, or maintain a pond. When we have different opinions we share them freely. And when we disagree, we do so in a civil manner and life goes on. Someone reading this forum in the future can see many differing viewpoints and weigh it out for themselves. But certain construction details are universally accepted. Fnishing an edge is one of them. (And I hadn't even gotten to the "string of pearls" -
@GBBUDD beat me to it on the one.)
For example - if I go ahead and lay my liner flat on the ground around my pond (and if you've followed other pond building advice to not cut extra liner you may have 2 feet or more surrounding your edge) and then cover it with say mulch or gravel.... how do I now plant anything on the perimeter of the pond? How do I keep that liner covered? How long before I decide to cut it back and now I CAN'T fix the mistake?
