MN Median Frost Dates
It is that time of year, thought I would post a link that shows a table of Minnesota median frost dates by region.
The fourth column of numbers is what you want to be looking at for the likely median first frost date in fall for your area.
Does not matter right now, but FYI the third column of numbers is what you want to be looking at for the likely median last frost date in spring for your area.
BTW the seventh column shows the average length of your growing season, in days, if you do not already know this information. Helpful when deciding which varieties to grow in your garden. :)
