Don’t let Iowa’s picture-perfect weather fool you.
Even in May, we could still experience a night or two of frost, as noted in a Czech tale brought to the United States by immigrants.
According to the Three Kings legend, the three kings or saints – Pankrac on May 12, Servac on May 13 and Bonifac on May 14 – were frozen when temperatures dropped while they were fishing at sea.
On May 15, St. Zofie came along with a kettle of hot water to thaw out the three frozen kings.
The legend serves as a warning to protect tender plants against a possible late frost.
In Iowa, it’s a good idea to wait until May 15 to plant your tomatoes, peppers and other tender vegetables and flowers outside, or at least provide them with protection in case overnight temperatures drop below freezing.
Iowa’s climate is similar to the Czech immigrants’ homeland, so many settled in the state to pursue farming and other occupations.
Other names for the legend include the three icemen – tři ledovi muži – or Three Ice Saints, and Three Frozen Men or Three Iron Men.
Perennials can be planted before the last average frost date, which is often even preferable before the heat of summer hits.
