Your Gardening Zone - Important Updates You Don't Know About?

I recently ran across the PlantMaps site and realized my gardening zone information and first and last frost dates are different here than anyplace else I've looked. Why? Because the site takes into consideration recent weather patterns.

I encourage you to check out your local information. I discovered my gardening zone had dropped a number - that's HUGE when it comes to having a successful garden!

UPDATE 1/28/13: One reader has written to tell me PlantMaps has completely incorrect temperatures for her area; for my area, it looks accurate. So do look at the specific temperatures the site claims for your area before deciding whether the information is reliable for your gardening zone.
