Let the weeds grow!
Plantain is one of my new favorite plants. We have a packet of heirloom plantain seeds, but when I realized these were already growing freely all over our property, I opted to let them grow where they already were.
Last year a friend shared a video about these amazing "weeds" and how to use them to stop a wasp sting--and then I got stung by a wasp and knew exactly what to do--it worked great!
Here's a great blog post about what plantain can be used for:
