Raised bed on concrete
Hello. I have an area of hard standing at the end of the garden That is a bit of an eye sore. I had to give my allotment up three years ago due to work commitments but really miss growing my own veg. I have four tanalised beds on order 4 X 3 ft X 14 inches. I understand that I will need to put in gravel for drainage but should I put a layer of gravel under the raised beds themselves to help prevent rot. The garden is south facing. I currently have a mixture of pots presently but there just isn't enough room.
