Careful foraging is a great way to explore the environment and collect free food! It is worth learning about our native plants and local foraging spots. My friend Emma is an excellent horticulturist and forager. She's writing a series of books based on foraging by the season and leads regular guided walks around Cornwall. Head to her site for more information.
