D. King, being described as a 'San Pedro' type fig:
Breba crop (fruit on last year wood) does not need any caprification (aka, fig wasp).
However, the 2nd (Main crop - fruit on the current-season wood) does need caprification - else it just falls off!
From what I hear/read, this fig, IS a King.fig for the PNW (a very good performer there).
