Maybe as important as mentioning pod-difficult cultivars is to mention "magic" pollen culitars that can miraculously break through the cycle of podlessness.
Every year I will find a pollen that sets even the most difficult plants. Unfortunately, I don't notice it until my season is nearly gone, and then usually don't remember it the following year...lol. Not an ideal plan!
Since we are on this season, I will tell you that both LAVENDER BLUE PLANET and CLASH OF ABSOLUTES, both from Curt, set pods on just about everything they touched. I used 50 wires of LBP and set over 40 pods. TETRFKXVICKI2 is a very difficult pod setter, and LBP left three huge pods on it!
I have a future intro from NANA NANCE X VICTORIA JOSEPHINE that has great pollen, but in three years....not a single pod...not even close. Noticed this morning that it had one from CLASH.
Maybe by mentioning it here, I won't forget to use them early and often next season.
