The Weeds State options include "Weed Free" as the lowest level option and "Mulched" as the highest level. I suspect the former is pulled weeds. In gardening, the use of Garden Mulch is supposed to help suppress weed growth and repel bugs (that's why cedar is so often used) as well as add nutrients to the soil as the woodchip mulch rots. I'm not 100% certain yet, but I suspect this was more along the lines of what is intended, otherwise Weed Free as a low-level option would be redundant and unnecessary. As I said, It's only an educated guess. I could be wrong. I hope we learn more about this feature in the future. Maybe a code diver will find it and figure it out.
