New this week is another (beta) search page for finding your frost dates:
The idea is that this will be a standalone tool (exactly the same as the new What’s My Zone search page) – it should work worldwide as it is based on everyone’s Folian Frost Date observations. For the same reason, it can be a little less accurate as we are dealing with real data so we need your help to make it as good as it can be:
Check that you currently have the most accurate Frost Dates listed in your Gardener configuration settings
To make sure at the start that we are using the most accurate data available, instead of using the search to check your Frost Dates, try and validate your dates with an outside source if you can. Frost dates can be quite difficult to find, so it would be great if anyone finds some good sources that they could list them in this thread for others to use.
I’ll start with a few that I have found in my travels around the net:
