The Wonder of Weeds

I've just watched an interesting little programme from BBC4, 'The Wonder of Weeds' presented by Chris Collins (available on BBC iplayer until next Monday). It was a mixed bag, some good, some boring but it was the last 10 minutes that truly held my attention. From an abandoned house Chris Collins showed how weeds were turning it back to nature, initially with the short lived plants that lived, died and rotted down to produce humus allowing new plants to move in and colonise the location. Ultimately the land is prepared and ready to grow trees again thanks to the succession of weeds that each had a role to play in it's transformation.
