|Please supply a list of alternatives for replacing my treated wood raised beds at a reasonable cost.|
|There are a number of recycled plastic products being used to make raised bed kits. If you'd rather start from scratch, these alternatives to wood are available from home centers and lumber yards. You might also try using untreated lumber which will last for a number of years. (Cedar and redwood will last the longest without treatment.) Other alternatives include cinder blocks, cedar shakes, and simply piling the soil steeply without using a retaining wall.
Because of the toxins in treated wood, it should be disposed of at a Hazardous Materials Waste Collection site. Please call your county solid waste district or state environmental agency for a list of local sites.
