I have a nice healthy zucchini plant in a pot in my GH. For several weeks it has had a lot of male flowers, but no female ones.
Will it ever? I know this has been discussed, but it is easier to just ask again.
Mine usually start with only male flowers and then some female flowers come later. You might enjoy stuffing the flowers with a cream cheese and herb mixture and tempura-ing them. That's what we usually do.
What makes me really sad is when I have female flowers open and no males and the baby zukes never grow :(
