Behind the back fence
When we bought our house, this is the area on the other side of the back fence that the former owners used as a trash dump. It was infested with invasive non-native plants. This is a before and after.
1 of 4: This yard is directly adjacent to a large plot of undeveloped land. Both the yard and the land are infested with star thistle (pictured), cheat grass, and tumble weeds (aka Russian thistle).
