Nice video. Not the best gardening advice. Wood chips lack nitrogen- they actually pull some nitrogen out of the soil. pH is around 5.5- 6.0. For neutral soil and acid loving plants, that's good- but soil here is already acid.
We are pretty much organic gardeners- we run a hellacious compost pile- leaves (for carbon) and grass cuttings (nitrogen). When it gets to cooking, it is about 160 degrees. Heat kills most weed seeds.
Chips make good mulch, and retain moisture, but encourage growth of fungus. Some plants don't like fungi.
Over the years we have built about a foot of good topsoil in our garden areas, mulch the heck out of our plants, have very few weeds. We add limestone for pH control and calcium. Without it, you will learn about blossom end rot on tomatoes.
What we have here is... failure- to communicate.
