It's been many years since I did botany at TAFE, but from memory I understood flowers need to be fertilised to produce a fruit (pod).
What I was getting at is how does this occur if the flowers/plants are covered? How do the bees do what they need to do?
I understand the concern of cross pollination and why it is undesirable. Just curious as to how the fruit sets.
