Blackberries are beginning to ripen so pick them soon tho in Scotland the Devil poisons the brambles on Old Holy Rood Day sept 26th .
Oh Weans! Oh Weans! the morn's the Fair
Ye may na eat the berries mair
This nicht the Deil gangs ower a'
To touch them with his pooshioned paw.
While in England it safe to pick them as he doesn't spit or urinate on them until Michaelmas Day. Some people say that the Devil is a traditionalist and keeps to the old calender (Old Michaelmas Oct 10th)
