Raised vegetable garden made over concrete slab

Hi,

      Can we place a raised vegetable garden bed over a concrete slab.  We are planning to raise the bed to 600mm high with drain holes.  Thanks Darren

Hi Darren,

 

                                  I think making a vegetable garden is an an excellent idea.   It is a good use of an area which is no longer of use otherwise.   There are no reasons why you should not make a raised bed on concrete.    Your suggestion to make it 600mm high is also a good idea.  I would suggest however to use a well drained soil mix to stop drainage issues.      Drainage is a very important issue when it comes to growing vegetables, so allow water to drain away from the base of the beds.
