Default Will herbs grow in 4" of soil?

I was thinking of putting a checkerboard herb garden on an area of
"lawn"(right off the edge of our driveway) that is mostly hard-packed
rock/lime and a bit of grass. The blocks I will be using for the
checkerboard are 4" deep so the soil where the herbs will grow will
also be
4" deep. Do you think I can get an annual crop of herbs to grow in
that? Or is that just too shallow? I won't be watering them since
water costs a small fortune here.


They will dry out too quickly. Not all herbs are drought tolerant.
Some get to be large plants and need more root space, more depth than
4".



I'm not going to get any that are over a foot high. And there IS ground
underneath, it just has the consistancy of pavement. I guess I'll find out
who the survivors are.

The nice thing about this is I can move it somewhere else next year if this
doesn't work. It won't be a permanent installation.



You'll be successful if you pick herbs that like your conditions. Some
plants respond quickly, others take time or become invasive. My sage,
rosemary, lavender, oregano and thyme have been growing well in full
sun without care except for an occasional trimming. (The oregano
keeps spreading fast, draws bees.) The odor can be overwhelming. We
have had up to a 7-week draught.
