ive read that some bees and pollinators do not reach the stigma
i know large bees do... i watched one yesterday on my P. Caerulea
ive also hand-pollinated that one, yet, still no fruit.
Not really worried about that one, its the Edulis i want to fruit.
Last year my 2 year old Incarnata ran 50ft along the fence
it put out dozens of flowers at a time
i hand pollinated several of those also.
For the 3rd year in a row, I had an Incarnata in a 5 gallon container.
it always seems to set fruit in the container
Last year, it was my only passionfruit of the season.
My theory, is, they will fruit much easier, if in a container
or, if the roots are somehow contained.
I may have read this somewhere too
I had a melon do the same thing.
now, if i can get my Edulis to even flower...
