Fear not daughter Olaf, I have now laid down the snake repellent at the Greek Hovel. Two canisters, as you can see below, 10 yards away from opposite corners of the house now emit a smell which snakes are meant to regard as foul and so will keep the hovel, if not the snake-fields, free from serpents for three months until Autumn hibernation. Well in theory.
Snakes, have in the past, ignored the foul smell and approached the hovel anyway. But in theory they are already slithering away. Fingers crossed. I was wading through longer grass today as I pruned my beloved olive trees. I trod heavily, as one does, but had no encounters at all with the wildlife diversity community.
I should note, without sounding too conceited, that there was relatively little pruning to do. Whover did the pruning in May did a very thorough job and should be very proud of himself.
