I'm making 16.5" high raised cedar planting beds for vegetables. Is MP-Global-Moisture-Block safe to use to line the inside of the planting bed (to block moisture from the cedar wood planks)? Is it safe for the soil and vegetables to stay in contact with this lining?Also, is this product still bio degradable? How often should I replace this lining?Or, this product is not designed for outdoor use in this way?

AFM's DynoSeal is what you want. That is our number one recommendation for wood planters beneath the soil. It will protect the wood from rotting and will not leech anything harmful into the soil or plants.Above the soil line, you can paint using AFM Exterior Satin Paint or Stain with Vermont Natural Coatings PolyWhey Exterior Stain.Your idea for using Moisture Block in this fashion is well outside the range of what the Moisture Block was developed for, which is going under flooring.
