Oh I'm not taking down the garage. When I said I didn't know what to
do with it, I meant the driveway. My garage is going to be a cottage
thing.

If the concrete is in good shape making cracks in it will be a big
effort, probably requiring machinery.

Yeah, I was wondering about that. I was thinking about making the
cracks in a pattern. I have no idea what jackhammering is like.


Hard work. The better the quality of the slab (ie thicker, stronger, more
steel reinforcing) the harder it gets.


I am not sure what you mean by this. Some plants will grow in cracks
in rocks and walls etc but it is no way to set up a garden as in
most cases the very limited room for roots will severely stunt the
plant. Also any plants that do grow there will risk being sun baked
on the concrete.

Looks daft to me, much work for little gain. Design awards don't always
consider the real cost and effort of implementation. Note that most of the
growth is up trellises around the edges not in the cracks.

Is your slab level? In most cases it would be. Water will not run off and
so there is an excellent chance of having a big drainage problem unless the
cracks go right through the concrete to some porous soil. Stunted roots,
plus baked when it's dry, plus drowned when it's wet equals dead plant.
