Raised gardening bed
Ok I have been gardening for years now,and now I want to do raised beds. In the picture is how I am going to plan it, the only issue I'm having is how deep... I was thinking about 16 inches whith a 2 inch gap from the top...leaving 14 inches to use...I am planning to build 4 beds and having perennial plants around the area... The other issues Im having are the type of materials to build from ( thinking treated lumber....I know, but going to lace the sides with plastic) and materials (also thinking just compost no or little soil ) looking for least expenive route..... Can someone give me some advice?
