Apparently seen in Romania. Place a row of small stakes (1.2m high from
ground X 1.5 to 2m apart), Then add a similar adjacent row around
40-50cm away (parallel) but placing posts between the previous row.
Fill the space in between with you prunings until compact barrier is
formed.
Does this type of thing have a name? Was it built by our ancestors (I
have a vague feeling of having encountered it before)?
What creatures may benefit. How long will it last? As it decomposes,
which plants best thrive... is weeding a problem?

Thanks.
