Here is a link to a USA Today article, which in turn contains a link to the new USDA climate-zone map. I think this is the first revision since 1990. Most of us are in warmer zones or sub-zones.

Pretty interesting. Mine has stayed the same. While most experienced bonsai folks are pretty in tune with the weather/climate and its effects, it's probably a good reminder for beginners to always be mindful what their trees are telling them about the weather/soil/water/everything in the environment.

Thanks for sharing Treebeard!

USDA Hardiness: 7B

Mine changed from 7A to 7B.  I've updated my profile.

Shoot, with the weather we've had this winter, it's been like Florida!  We've only had a couple of days of serious frost.

One thing to consider that Michael Hagerdorn recently did a blog post about is that hardiness zones (I'm paraphrasing) are good for trees in the ground not bonsai as the roots don't have the same insulation.  Obviously a good overwintering plan that protects your trees will negate risks.  One thing that is good to consider with new bonsai is where they came from; a tree from Florida now living in Ohio may not be as tough even if the species is "hardy" in both places.  When buying seed to grow bonsai, it's also a good idea to check the provenance (where the seed was collected) as seed from a colder locale is good to use.

Yup I've changed too. Updated my profile to 4B. But as it has been said, this is for trees in the ground.

Maybe they didn't bother updating us coastal folks since the data show we will clearly be underwater in a few years. Not worth the trouble... Grin
