Hardware cloth apron for digging protection?

[Bear Foot Farm]

can the apron be effective if it is flat on the ground along the perimeter on the inside instead of outside?

Not really since no grass will grow to anchor it in place, and predators can still dig under it

So the long Leg of the L is up against the wall, and the short leg is on the ground?

It will work better the other way around​

So what could replace an apron for the half of the fence that borders the property?
