Landscape fabric - safe for organic garden?
I'm planning on building wooden boxes, a la Square Foot Gardening, to grow veggies in.
I was thinking of using scrap wood to do this - untreated wood pallets. Because they are somewhat irregularily shaped, I'm thinking they won't form a very good seal, and soil would escape.
So then I thought I would line the boxes with landscape fabric, before filling them with soil.
The question is: does landscape fabric leach any unwanted chemicals into my organic soil?
