Not exactly vegetable garden, but a fruit tree update, I thought they are kind of in the same "category".
I built a big concrete planter last week (well, I built a mold and cast a planter in it) - it was an experimental one (trying different materials for the mold building) - but it came out ok (learned a lot from it, both good and bad), and once I managed to flip it over and clear it from all the sand I used for the cavity, I moved that 360 lbs monster to the deck and we went to look for a dwarf fruit tree we could put in it.
Given that it is San Diego county, it is warm and there is lots of sun, decided we wanted a dwarf fig tree (good with sun, do not need tons of water once established). Apparently, there is a type called "Little Miss Figgy", unfortunately, the nursery did not have one so we had to settle for a different kind of fig tree, but that's the new addition to our fruit trees - surprisingly, already starting to show figs. All our other trees (apples, lemons, avocados) are not grown in a container, so it will be interesting to see how this works.
FWIW, this tree stands next to our little herb container we have on the deck which currently has mint, basil, cilantro and parsley in it.
