Now I know why many ancient races have rites and rules about trees. The Jews have a special day for New Year for trees as well as numerous strictures about when to harvest and never to destroy a fruiting tree, even in war.
We have managed to harvest tens of kilograms of these beautiful, large 'blood plums' in the middle of January - some we have given away, some are now jam, compote or plum cake (see photos - recipes on request).
