2023 USDA Plant Hardiness Zone Maps Out
« on: November 19, 2023, 12:01:31 PM »
Was checking it out a few days ago. I went from 7b/8a edge to a strong 8a now. Very much in the middle now of the 8a band. How has y'alls changed? More citrus to trial  :o

I am in Colorado. I was traditionally in zone 5B and am still in 5B.  No global warming in Colorado.

Don't rely on that!

Austria has +3C on an average and summers get dryer and dryer.

I'm not really keeping track of how it changes here, but while it's clear that our summers get hotter (and more dry) it doesn't necessarily mean winters will get warmer. Or the average temperature in winter might be warmer, but it is possible that there are still (short) freezes that are very cold.

Climate change is sometimes more like climate disruption with more extreme weather as possibility.
