If the kernel is spoon-shaped, lots of heavy, wet snow will fall.
If it is fork-shaped, you can expect powdery, light snow and a mild winter.
If the kernel is knife-shaped, expect to be "cut" by icy, cutting winds.
If this is true doen't it mean you're going to get snow? This is good?
I don't think it's common to find persimmon growing in the UK, Arn't they from the mediteranian?
There are other ways said to predict the winter in the UK; an abundance of hedgerow fruit, hawthorne, rosehips, sloes and so on are supposed to foretell a bad winter to come as are early arriving geese and nut-hoarding squirrels.
