Sorry, but as someone who has studied, lived and worked in Germany, and a regular visitor, this article does not pass even basic fact-checking. Just about everything in it is complete rubbish, or a massive generalisation.
Germans may, or may not, weat shoes indoors. No real difference to, well, anywhere.
German floors are not cold. German heating is as good as anywhere else.
It is not uncommon to see children with no shoes in their prams. Again, pure personal choice.
Germans don't go insane as soon as a seasonal vegetable becomes available, with the possible exception of asparagus, which does indeed get great publicity and a sudden surge in (generally vastly over-priced) specialities and local asparagus - based delicacies. Otherwise, no. Possibly certain local customs, but nothing more than anywhere else.
Germany doesn't have a committee deciding if your name is OK. In common with many European (and some other) countries, there is a list of acceptable names, which is well known and very wide-ranging. If you want to call your kid Apricot Trampoline Kit-Kat God, you can apply for it (which can be expensive) and really should not be having children in the first place.
Herman's are not banned from staying overnight in country homes. Indeed, having a second, rural, home is a middle class statement and very common. Many small villages are made up almost entirely of second homes, used for weekends and week, two week holidays. I think you may be getting mixed up with garden sheds and huts on allotments, where such rules often apply (as they do in most countries).
There are few, if any, set fines for insults. It depends on who is doing the insulting, how drunk or potentially violent they are, and who they are insulting. If you insult a police officer you probably will get a fine, although a warning would be more common first time. If two drunks in a bar insult each other the chances are they will fall over and sleep it off.
And while gardening clubs and vegetable patches are common in Germany (all types of clubs are; if three Germans meet on holiday they will have formed four clubs, complete with elected officials, a comprehensive rulebook, and club emblems and badges, within 24 hours), they are nowhere near as widespread as they are in England, Ireland or, indeed, Russia.
And both types of potato pictured are grown, and available in the shops.
There are many peculiar things in the German psyche, many customs and ways of looking at life which seem strange to outsiders, but this article quite obviously doesn't have a clue what they are.
