I wonder if this will include Canada ? I can’t find a new map for my country, but I have heard about it on several local news stations.
For the first time since 1990 the U.S. Department of Agriculture has revised the official guide and it seems like almost everything has changed. Ohio, Nebraska and Texas are in warmer zones.
“The Zone Map is a mainstay of 80 million home gardeners, showing the average annual extreme minimum temperatures at a given location during a particular time period. Gardeners use the maps to determine whether seed and plant varieties are likely to survive in their areas.”
I know this can be bad news for crops and for much of the agricultural world. But, I can’t help but feel a smidgen of joy that the climate around us is getting warmer. I know I know, shame on me for saying it. Global warming is bad.
Many plants and shrubs I’d love to grow but can’t because of my cold zone just may come true someday. I mean, so far this winter with the temperatures we’ve been having puts my area at like a zone 7a. Although, last year at this very same time we were experiencing -30C for a few days straight. Hello zone 4. Brrr.
It also looks as though new zones were added in for Hawaii and Puerto Rico – 12 and 13, meaning that their winters are warmer than ever. Not like they get cold winters anyway, but still, that’s a major change. Also, for the first time, calculations include more detailed factors such as prevailing winds, the presence of nearby bodies of water, the slope of the land, and the way cities are hotter than suburbs and rural areas.
Gardeners have known for a while that the climate is changing, it’s not really big news to us. We know what works for our area – what will grow and thrive, what won’t. Though it’s great that the federal government is keeping us gardeners informed with what the plants have always known… where they can survive.
