Lining a raised garden bed with plastic??
Built a raised bed from deck posts. Sides are about 6" tall. Wondering if lining sides with plastic is good idea to retain moisture since most of the plants' root system will growing in the 5" worth of compost I'm filling it with until they set root deeper down.
Also, thought it would keep dirt from 'leaking' thru side gaps between the two levels of wood posts.
Have very hot, dry summers and have to water normal garden too much already, so don't want to have to water this one even more.
