|when Using cement blocks for a border should a plastic liner be put down under the dirt to prevent soil loss or would this prevent good drainage?

|The plastic would inhibit drainage so if you'd like to line the raised bed, use weed blocking fabric. It has tiny holes which will allow drainage but won't allow the soil to leach out of the bed. Look for Weed Block in your local Home Depot garden center. Good luck with your raised bed!
