Hello
I am planning to build a brick herb box after my garden patio. The box
will be 900mm high (from patio floor), 5 meters long with 300mm planting
width between the brick walls. This will also act as a wall for the
garden patio. The brick wall will be half brick (102mm) on each side.

I would like to know what I need to consider during the build. Is the
brick wall structure (thickness) ok, water proofing, drainage, mortar
mix etc? Your advice would be much appreciated. Any good websites?

Thanks

Have you considered using flower pots? My herbs are in 12 inch (30 cm)
pots arranged together at the intersection of two paths in my garden.
See my http://www.rossde.com/garden/garden_back.html#herb.

I find several advantages to this. Some herbs can be quite invasive
(e.g., mint, oregano) and will crowd out other herbs. Some require more
water (e.g., mint) or less fertilizer (e.g., sage) than others.
Eventually, some will require dividing (e.g., tarragon). Flower pots
allow you to confine each herb and to give each its distinct care.
