My experience is that each plant has both male and female blooms. Sometimes the first blooms are only one or the other for a while, but eventually you should be getting both blooms. My first blooms were female, and no males, so they just died off. Then later they had some of both. I picked my first zucchinis yesterday. I had some yellow croke necks a bit earlier. I should have some hybred Zepher ready to pick tomorrow. I planted seeds around the first of June. Do your vines look nice and vigorous? No off colored leaves? Putting on growth at a rather fast rate? If you can answer yes to these questions, you should be getting some zucchinis soon. And then you will have more then you will know what to do with. I ususally plant way to many, and end up with a lot of extras. I feed the extra to my chickens, who love them after my friends start to avoid me thinking "Oh my God, not more zucchinis!"
