re. raised beds


one other option for raised beds is to use regular lumber and to line the inside (the side facing the soil) with corrogated plastic.  Sign makers will sell thin strips of it cheep, because they often have excess off-cuts, or might even give it away to help a community garden.  We got some free.  The wood will still weather as it is exposed to the elements (good idea to stain or varnish), but the side facing the soil should rot more slowly because of the plastic protection.  Nothing lasts forever.
