I tell you Jon......I am considering it! Some of my prize trees are 5'+ tall and are great producers this year. My Italian Blacks, Black Maderia, VdB, Hardy Chicago, LSU Tiger, KB, RdB, Negronne, Don Fortiss, Black Celeste, Petite Negra, Smith, IC, and a few others are truly AMAZING!!!
So, this Fall, I may start culling those non-dark ones except of only a few.
