If the faster spreading plants in your garden take over
here are a few ideasĀ of recycling them:
put them on Freecycle
give them to charity to sell (see pictures at Car boot sale in Muir of Ord in aid of refugees)
if you live somewhere with passing traffic, pop plants up to the road and put a wee sign up to advertise free plants, with the option of a donation given to a charity of the takers choice (that way you don’t have to deal with the money either)
