I saw a post earlier asking “where our advice is coming from”. Part of the discussion suggested we list our hardiness zones to help out. A few weeks ago I donated to arborday.org. While on their website, I found a hardiness zone look up. This will work for those of you with US Zipcodes. Those of you outside the US might contact arborday.org request a tool that works for your location.
Keep in mind that these zones are based on your zip code only, so your micro-climate probably won’t be taken into account. And, I would assert that the basis of our zones is changing very rapidly. When I moved into my current Seattle home I would assert we were a zone 8a, now we have years when it feels more like a zone 9.
Times they are a changin’!
