There's no sign of any heatwave here at the moment! It's like November out there today! Dark skies, howling wind and rain.
My veg garden failed almost completely this year, for some reason, except for the bean family. They all did ok. But from an entire pack of parsnip seeds, I have FOUR parsnips! And from 2 whole packs of carrots, I have maybe a dozen carrots! I replanted carrots twice, and then gave up. Not sure what the deal was with the garden. I was watering in the dry spells, but it just didn't seem to do much good! Weird.
I remember hearing that in histories from Medieval times, there were always references to people dying from "the bloody flux", and it was thought for years that this was some sort of virus or illness. It was only in the 20th century, when more work was being done in Africa with the victims of famine, that it was realised that "the bloody flux" was in fact the last stage of starvation, when basically, the insides broke down and came out in a bloody diarrhoea! There is no recovering from that. And this was so common in Medieval Europe, Britain and Ireland, that they thought it was a virus! Apparently, on average, one in four harvests failed, but around the Middle Ages, there was a succession of years where the weather was bad and the crops failed or never got planted, and there was famine. Entire communities were wiped off the map.
