Like many Michigan gardeners the especially mild winter has raised hope for starting the garden early this year. The trouble is though, that I KNOW we're still likely to have a hard freeze, some snow and possibly a lot more winter. I was interested however when a friend on Michigan's west coast mentioned that her area changed planting zones. Did mine? So I set out to discover and answer to my query.
Sure enough, my zone has changed from Zone 5 to
Zone 6a. An altered planting zone... What??? What does that mean? What new plants can I add to my collection that I don't already have, or that I have been dreaming of... I don't know the answer to that just yet, but it is interesting to notice the shift in zones throughout the United States. Changing our hardiness zones is nothing new though, as recently as 2006 there was a big
shift in hardiness zones from the 1990's.
