When we installed and filled the new metal raised beds we included a riser from the irrigation lines. Once we determined what would be planted in the bed we could install a manifold and install the appropriate drip irrigation lines.
Ready to go.
A kneeling pad is a necessity when working in the garden, especially at my age. (That mulch is dangerous.)
Pipe cutter for the riser. We decided to install a different type of outlet than we usually do. Only four outlets and only one adjustment for all the outlets.
All finished. It works great and she already had beets planted.
