Working on a raised garden bed with hopes to increase the size and amount of the fall / winter garden crop.:

The size of the raised garden bed is 8′ x 6′ x 2′ After outlining the planned bed, we made a first pass at leveling each side. Once we achieved the leveling within acceptable tolerances, pressure treated lumber was placed and screwed down one layer at time. One additional cross member was installed to avoid outward bowing due to the weight of soil and the height. Filling the raised garden with garden soil is labor intensive. We bought 3 cubic yards the vegetable mix. A front loader placed 1.5 cubic yards into the bed of the truck as that was just about all that would fit at one time.   After two truckloads of soil, the raised bed was full.

Next came the question on how to water. After running a hose back to the lawn sprinkler system, and then connecting an additional sprinkler head to a hose bib mounted to the side of the raised garden structure we were able to water the garden area as needed. The concept works great as we now can water the garden at the same time the automatic lawn sprinkler system comes on to water our lawn.
