As summer draws to a close a lot of things people like to do wind down. The baseball season, water skiing, and of course gardening. While Idaho gardeners will be planting well into September, this is the unofficial end of the summer gardening season. At this time of year many gardening stores have big sales.

Adam Cotterell takes us to the gardening world’s equivalent of Black Friday. Call it Green Thursday.
