Blackberry winter
From Wikipedia, the free encyclopedia
In South & Midland North America, Blackberry Winter is referred to as a period of cold weather in late spring when the blackberries are in bloom. This is generally in the month of May and is known to last approximately 14 days.
Prior to technological advances in meteorology, farmers would use such terms to know when to plant certain crops. Blackberries must have a cold snap to set buds on the blackberry canes. It comes with a somewhat less severe return of a continental polar air mass after the maritime tropical air masses have begun to dominate the weather. So, there will be a cold snap when the blackberries bloom, called Blackberry Winter.
