Hi everyone,

I have built a raised bed from cedar and am planning to place it in my yard in a section that has very vigorous maple tree roots running through the entire section I plan to use. They are under the soil, of course, but I anticipate that the maple roots will happily invade my new bed. It's an ideal spot in other ways, so I would really like to be able to use this area despite the root issues.

I'm looking for a good root barrier material. From my research it looks as though landscape fabric may be ineffective and biotech root barrier fabric may inhibit the roots of the vegeys I intend to plant (as the product I found releases trifluralin above and below the surface of the fabric). I know that commonly this fabric is installed vertically, but I'm not sure I'm up for that level of effort! I'd prefer a material I can attach to the bottom surface of the bed.

Any suggestions for me? Thanks for your input!
