I planted some National Pickler (NP), Little Leaf (LL) and Marketmore (MM) cucumbers again this year. Marketmore and LL are producing well and taste great. National Pickler is only producing massive amounts of vegetation. No fruits- no flowers that I see. All planted in same soil, why would one not flower and produce while the others are fine?
After I thought about, NP did the same thing last year but I had forgotten that. In years past it has been an excellent pickling cucumber for me.
