The first thing I will try is to make them climb: 3 poles in "Indian tent"; a strong wire mesh such as those we put in concrete slabs ????
Maybe the climbing alters the hormone flows and this "unblocks" flowering / fruiting. Just an idea ...
I noticed this too, my potimarrons climb above the edge of boxwood and often it fructifies at this place, but I also noticed that without size at the beginning it is already necessary a beautiful length of stem to have a fruit especially on the pumpkin
for pumpkins it's shorter, but next year I'll do my own feet and I'll prune to multiply the stems
