With mucho help from my Father-in-law:
Bolted the two short pieces of lumber to the two long pieces of lumber to create the 5' x 10' garden box.
Sprayed round-up all underneath where the garden's footprint.
Laid the fine mesh down under the garden box to prevent weeds from coming up, but to allow water to drain.
Poured the 10 bags of potting soil into the garden box to form a raised bed and spread soil evenly.
Placed all veggies and herbs and arranged tomato cages and cucumber fence / trellis (an opened triangular tomato cage).
Watered heavily - even more on the tomatoes.
