Herb Garden Bed

I took advantage of another temperate day to do some landscaping work. We have incorporated an elevated herb garden bed as part of our retaining wall. Two sides are fabricated from weathering steel and will eventually have a rust patina. I moved excess clay from the upper section into the bed, lined it with filter fabric, added crushed stone to the sides, and filled it partially with topsoil leaving room for compost to complete the bed. The garden will be about 12 feet by 4 feet in size with a massive flat stone serving as a platform from which to tend it.
