How to build a garden brick wall?
If it is a low wall then dig a footing, lay a 6″ bed of concrete with about 3″ on each side of the blocks. Bed and lay the blocks on mortar and point up. If the wall is going to be of any significant height (i.e. can fall on someone) or you are not sure of the ground conditions then get someone in. If you do go for it make sure you use a level at all times (vertical and horizontal).
