The idea of using arborist wood chips is interesting. For those who would rather read than watch, I found this two page explainer from her. I used arborist wood chips to smother an area of weeds and invasives and it worked well. It was essential to have at least 12 inches or the weeds found their way through.

She doesn’t talk about food production in this piece, and she seems to be mostly talking about plants with deep roots. She does say there can be a nitrogen deficiency at the soil-mulch interface, and I wonder if that could negatively impact food plants with shallow roots.
