Peach, Sorry I didn't respond in a very timely way, but yes, you could use burlap as a liner. By the time the fabric fails, the plants will be rooted to the point that they will retain and hold soil in place. I've found that you don't need much soil for most plants. Experiment. Do a quick search on hydroponics and you can learn how to grow with no soil at all and still pull nutrients from your pond. I'm actually going to try to grow some edibles on my pond this year. I'm attaching a pic of a tire still on it's rim (from the web) that grew a few weeds for inspiration smile although I'd only use the tire in order to build a more attractive planter. I wish I'd taken pics of mine before they were covered in ice and snow. Hope to make some more this spring and put the build pics on the forum.

Your question was also directed to Dono, but I think he was referring to plants that are planted into the bottom of the pond.

Happy Birthday too! I think I saw your name up there last week.
