According to the farmers' rule, plants should only be placed in the garden after the ice saints. Why is that or is it just a myth in the end?
The last cold period with a risk of night frost
The ice saints are also known as strict men or ice men. The ice saints are from May 11th to 15th and are called Mamertus, Pankratius, Servatius, Bonifatius and Sophie. These are bishops and martyrs from the 4th and 5th centuries. In northern Germany, Mamertus is the first ice saint. In southern Germany it is Pancratius. What is meant by the ice saints is the last cold period with the risk of night frost.
Claims have not been proven
The rule dates back to times of weather records made by farmers over many centuries. However, these claims could not be proven. One should also not forget that the climate has changed continuously in recent decades. In addition, weather statistics show that the period from May 21 to May 23 is more susceptible to frost.
Peasant rules cannot be generalized
Nor can you generalize farmers' rules, because the climate on the North Sea is different from that in the foothills of the Alps. It may well be that there are still frost nights in mid-May, but they cannot be fixed on the date. So the rule that plants can only be brought outside after the Ice Saints is a myth.
