drainage. Our land slopes, the previous owners put in a brick retaining wall for a level garden bed. It had zero drainage, so was essentially a bathtub. The pipe is socked 65mm AGI, the arms slope down to the centre line, except the last one that the centre slopes into, and then goes out a drilled hole that will hook into further drainage. Finish gravelling over the pipe, fold the geotextile over like a fat sausage, kick the dirt back and then later putting in decorative dividers that will mimic what used to be a pile of concrete and brick bed dividers I painstakingly dug out.
