Post-Mother’s Day frost

frost-covered car I’m pretty sure heard one of the MPR meteorologists last week advising people to wait till after Mother’s Day to plant annuals and vegetables.  If so, oops! There was patchy frost here in Northfield this morning. Our backyard thermometer read 33 degrees and my car windows were coated.

I see former Strib/WCCO meteorologist Paul Douglas is now blogging for the St. Cloud Times. His blog post Sunday morning says:

Don’t let the daffodils and tulips fool you. Only the brave (and foolhardy) are planting annuals this early. Last night’s patchy frost was a rude reminder that frost is quite prevalent across central Minnesota through the third week of May. The general rule of thumb holds: if you want to be ABSOLUTELY safe: wait until Memorial Day to plant your vegetable patch.

  1. People do and should be familiar with enough to know where their garden mini climates are located.
    Outside areas near windows or walls can be a few degrees warmer than places that don’t have protection from wind and are highly shaded during the day. Of course we wish to err on the side of caution, but if you know what you are doing, you can get another week or two out of the season.

  2. NWS predicts 39 tonight, and 34 Saturday night. That is awful close, especially Saturday with the moisture in the air.

  4. I was also going to say that the forecast was for 39 last night, and I am showing 36 right now. We are going to be covering everything and heating the greenhouse tonight.

    Good luck to everyone tonight. I hope that everyone didn’t plant too early. 😎
