Historic Freeze in MN tonight: When is your First and Last Frost? Looking at the Frost dates USDA chart
We in Minneapolis are suppose to have a record breaking freeze tonight.
I plan to harvest like crazy today and drape plastic over my PVC pipe trellises and anchor it with left over bricks I have, and of course bring in all my pots outside. And pray.....
In Minneapolis our first known frost is Sept 15th, and we are talking a freeze not a frost. Wow what a short season we are having this year! We had a very late spring (the year before we had an early spring) and now a freeze on Sept 13th. I guess you never know what to expect with the weather when you live here. Thinking about frost and freeze dates I pulled up the USDA frost and freeze chart by zones and thought I'd share it to help everyone plan their fall gardening.
Please note that the dates on this chart are approximate. Most years, the first and last frost will fall within two weeks of the date on the chart, but some years, we get a very early frost or a late snow storm that throws the dates off. Use your judgement (and your local weather forecast!) along with this chart to plan your seed starting and planting.
