Hi
I'm planning to build a few concrete block garden beds, probably three
blocks high, ten blocks long at the max, on a concrete floor.
What are the growing mediums better suited to this?
Is it a good idea to waterporoof/seal the inner surfaces?
Do you have to use mortar for a wall three bricks high?
Thanks all
Peter


Might pay to drill holes in the concrete as you will need to have drainage,
as you will end up with dead plants with too much water at root level. Is it
going to be a garden bed or a veggie patch, you should not need mortar as
others have done the same with no problems.
