It is always best to use scrap timber or other materials for a raised bed as the sides eventually rot away. There are plant friendly wood preservatives, not organic, but even these most people would not use near vegetables.

The most durable timber for raised beds would be larch or possibly elm and alder, the latter would be hard enough to get. These timbers have natural anti-rot constituents.
