Who Are The Three Ice Men?

Perhaps you’ve heard the old proverb that warns not to plant until after the “Three Ice Men” have passed, but do you know who these mysterious Ice Men are? We explain.

Perhaps you’ve heard the old proverb that warns not to plant until after the “Three Ice Men” have passed, but do you know who these mysterious Ice Men are? The tradition comes from Northern Europe, and is tied to the successive feasts of St. Mamertus, St. Pancras, and St. Servatius, whose respective days occur on May 11, 12, and 13. They are also sometimes referred to as the “Three Chilly Saints.”

Who Are The Three Ice Men?

In Europe’s not-too-distant past, parts of the continent remained rather cold through the middle of May, making planting before then risky. German and Swiss lore refers to mid-May as “Iceman Days,” while an old French saying states “Saint Mammertius, Saint Pancratius, and Saint Gervatius (the Francophone spelling of the three saints’ names) do not pass without a frost.” Because the agrarian people of medieval Europe weren’t likely to be literate, let alone aware of calendar dates, they measured time by observing nature and by the church calendar.

Remembering that the last frost of the year generally falls around the feast of Servatius was a useful marker for pre-modern farmers.

More “Chilly Saints” Lore

In some regions, the lore goes on to note that rain will fall on Feast of St. Sophia, marking the beginning of planting season. For this reason, May 15 is referred to as “Zimna Zoska,” or “Cold Sophia” in Poland.

One point of interest is that this bit of lore dates back to before the creation of the Gregorian calendar in 1582, at which time most days of the year shifted somewhat. While the feasts of the Three Chilly Saints are still celebrated from May 11-13 on our calendar, these days used to fall a little later in the astronomical year: May 19-22.

We live in Colorado at 8400 feet above sea level and the only way we can plant early is to start almost everything indoors in a grow tent, then transplant them into our greenhouse by end of April. Tomatoes, cabbage, zucchini, carrots, strawberries, snap peas and strawberries are all growing well out there. Peppers will be transplanted mid to end of June to avoid loss. With wildlife and weather fluctuations here, the best thing to do is invest in a good greenhouse complete with water, heat and air circulation.

My dad always said plant after Easter. So I still follow his rule. It’s served me well.

Memorial Day was “Planting Day” in our family when I was a child. Many I year I bicycled to my Grandparents’ home to help my grandfather with his planting while we listened to the Indy 500 Race on the radio. No transistors back in the Forties, just a long extension cord and an old radio with lots of tubes.

Catherine Wingfield-Yeatts

We always wait until mid-May, or until the last frost day is forecasted to plant. But usually, mid-May. Today, is June 19th, and it was 44 degrees this morning. I’m sure the tomatoes, squash, and cukes are not happy campers. I hope the green beans and butter beans are okay, too. The weather has been jerking us around. Upper 80s and low 90s, then beautiful 70s. Then back up. Then down.

Derby Day is my calendar milestone for planting.


I planted after Mother’s Day but Mother’s Day came early this year. I’ve had to cover up a couple of my plants because it has gotten so cold at night. My peonies always bloom by Mother’s Day. That’s what I always gave my mother for Mother’s Day. They’re just budding now.?

Rena Brannd

Our mother always fixed the ground for the garden starting 2 weeks before Good Friday. Come Good Friday everyone was up planting the garden sometime just barely a day break the garden had to be completely planted that day and watered good. She said her mother and grandmother always did the same thing, and come Easter morning you could see the ground breaking open and a little sprout coming out. This was the teaching of the crucifying of Christ. The soldiers came and got Christ at day break and He was beaten and went thru struggles and all kind of pain all day long and at the end of the day the wrap in in sroudded muslin cloth and buried him and on the 3rd day(Easter) He arose from the grave with new life and new body. (My mother’s mother would take and old thin rag of muslin or cheese cloth with a handful of fertilizer in it and wrap the seed in it then bury it.

Mike S.

Here in N. Georgia, I usually start around Good Friday. This year I’m running late because of a few cold nights.

My Dad referred to this time as “Iron Men” sometime around the first week or so of May. I believe it was a Bohemian (Czeck) tradition. He was always right, we get nasty weather in St . Louis the first week or so in May. I never put out tender plants until after Mother’s Day.

Mary Jo Digel

People laugh when I mention the three ice men but this is really a fairly accurate gauge of the weather. At least here in mid Ohio. Mother said to never plant before May 20.


I’m in Wisconsin. My parents and grandmother never planted until after the three ice men days either. So I don’t either.


I always plant after memorial day to be safe. Bringing the seedlings out on nice day before then. But for tomatoes and beans in direct ground with other seeds squash etc. Works for me in CT


Illinois resident here. My father was a farmer all of his life and always told us to wait until after May 15th to plant our above ground crops.

Skiff Hair

We here in South Carolina, tend to not plant our outside plants, tomatoes, peppers and such, until after the Masters golf tournament. That is usually our last frost. This year seems to be a little different. I have covered my outside plants, just in case!

Mother’s Day Rule & the Farmers Almanac!

Marianne Allbright

In the past I’ve always used the mother’s day rule but since we’re supposed to have lows below 40 through Tuesday I think I’ll wait until the 14th this year to plant -which is the next good planting day according to the FA gardening calendar.


My dad was a farmer in Illinois & swore by not planting a garden until after May 15, the last frost free day.


I set out my onion sets in mid March and tomatoes,beans and peppers the last week in May in North East Ohio


i always planted after last frost which was april 15th in hampton virginia. but with the way the weather has been lately, i haven’t even planted seeds in my flower garden.


I live in Michigan and never plant my warm weather plants until Memorial weekend. That’s the way my grandparents did it.


Better to be later then early, it’s all the same in the end. Miss those days.


I knew there was a reason why I couldn’t really start up a patio container garden until the end of May, the start of June even though the sites I was ordering from claimed that my grow section was earlier. I would order later which limited my selections. I will remember this to use these dates as the start of the growing season in my area, especially since on this upcoming weekend May 8-10th, 2020, we are having March temperatures which also continue through until May 15th, 2020. Sometimes these proverbs are based on real circumstances.


Here in Canada we wait until the long weekend . Victoria day in Canada May 18th this year . Much to cold before that . Had snow today may,8,2020.

My grandfather always said to wait until after the May full moon (here in Maine). He was a gardener for many years, and I don’t recall him ever complaining that a frost got his crops. I have always followed his gardening advice and have not been disappointed.


My grandmother used to tell of a year in Rockford, IL (very northern part of IL) when there was a killing frost every month of the year. Unfortunately, I don’t remember the year, but I think it must have been early in the 1900s as her children were born from 1902-1912. Very hard to deal with as she grew, canned and preserved most of their food for the winter. Hard times…..


In many years past here in New England, Memorial Day weekend was the time to plant. But in more recent years planting has been a week or so sooner due to warmer weather. But as with so many others we have snow coming this winter. That’s what’s unusual!


I live in the foothills of the Adirondacks, central NY, and my 93 year old mother has never planted anything until after Memorial Day. Her gardens have always been beautiful.


Your perennials will probably come out of it OK. Annuals probably won’t survive.


I usually wait for first of May here in the STL area but planted early bc I was at home! But now there’s a frost warning tonight!

Mary Evans

I’m north of Troy, Mo and planted early this year also. I was home so I had plenty of time to get it done. Covered everything and nothing got frostbite!


I live in NE Ohio. We are in for some snow accumulations tonight and a freeze warning. At this time of year, our meteorologists usually caution not to plant until after May 20th when we usually are safe from frost.


Always the Mother’s Day Rule! My parents did too. It’s only been 1 time in my 65 years I’ve had to cover the plants.


I live in Colorado. Last year I didn’t plant my garden until June 6th.


In Kentucky we often hear that we should wait until after Derby Day (first Saturday in May) to plant our tomatoes. This year we’ve had a frost and are having a freeze tonight, a week after Derby Day…although we really didn’t get a Derby Day due to Covid 19. Confusing times.


My biologist husband always says to wait until after Mother’s Day. This year, 2020 I definitely have to as this weekend is dipping into the 30’s at night here in SE Pennsylvania.


Around mother’s day where I live.

Jacqueline Stickney

Because we can never trust the weather in Michigan, I don’t plant until Memorial Day. It’s safer then.

Jenifer Wilde

I ALWAYS plant by the Farmers Almanac no matter what region I live in….Usually by Mothers Day is my rule. Although some years it has been St. Pattys day


I live in central Wisconsin and always wait until after the 20th-22nd of May to plant.


We live in New England and we always plant on mother’s day

Cabango Bongo

I live just outside of Chicago – we have daffodils and some tulips now. I’m planting my sunflowers and peas and beans next week.

Robert Herndon

In Tennessee, many say not to plant before April 15th, however unless it is a cabbage-like plant, I will not plant before the first week in May. Down here, we have “Whipoorwill Storm”, “Redbud Winter”, “Dogwood Winter”, “Locust Winter”, the Easter cold snap, and “Blackberry Winter”. Most springs, we have exactly enough cold snaps to fit these winters, but sometimes we have to add some. The last one, “Blackberry Winter”, usually marks the last one where it’s safe to plant which is right after the first week in May.

Dianna Ebat

I live in the front range of Colorado. I find it best to wait until after Memorial day to put out plants. I suppose seeds can be covered, but I don’t like disappointment when we have either snow or hail around memorial day and all the efforts are ruined in a split second.

Janet VanCamp

I’m from Ely, Nevada where it’s always cold. Someone will always try to plant Memorial Weekend, and if by some miracle plants sprout they will always get it when our final freeze comes in the middle of June. We have an amazingly short growing season here. Our early freeze comes early to middle September.

Faye Bancroft

We live in central lower michigan, and usually have a killing frost in early may. I start seedlings in april, but nothing gets planted in my garden until June 1.


Here in northern Kentucky (Louisville) we generally wait until after the Derby. Kentucky Derby that is. It is notorious for any kind of weather….rain, tornado’s, snow and even sunshine. Derby falls on the first Saturday in May so it is safe to wait until after Derby day.


I start seeds inside in late February and use cold frames and this year an unheated greenhouse for my plants. Here in northern Michigan I have had tomatoes, lettuce, spinach, peas and cucumber plants in the ground. They must be covered well at night. All good so far.


Here in central NJ its usually safe to plant the garden on or after May 15 when threat of killing frost is over. I start tomatoes and green beans in peat pots on the deck so that they can be readily covered in case the temps drop too low over night.

Kathy H

We live in the Panhandle of Florida and can usually start planting early to mid March. There is always one frost during Spring Break before Easter.

Jack Carrigab

We live in Wisconsin & today my car temperature was 46 degrees & it was cold & rainy, so I expect the 3 Icemen to show up around the 11-13 of May… By the way, I cancelled my golf game for today… Too chilly for me today…. The King…

Ky girl

In Kentucky we have , Redbud winter,Dogwood winter and at this time,Blackberry Winter.After this one passes we shouldn’t have to worry about any more frost.


Yes, I do wait until after the 15th of May to plant our summer vegetables and fruits. Tennessee is notorious for the mid May frost.
