May's focus at BlogHers ACT Canada is on eco-gardening.  Does this sound redundant to you?  Ideally, all gardening practices would be ecologically friendly, but the fact of the matter is, many are not.

Every year, thousands of gardeners all over North America head out to shop for flowers and vegetables, taking all kinds of non-biodegradable plastics home along with their plants.  Most municipalities do not recycle these pots and flats, which then end up in landfill sites.
