Hi coach. You may have noticed some of the flowers have the embryo fruit and others have no embryo and are on a long stalk. The ones with the embryo are the female flowers, the others are the male. Pick a male flower, peel off the petals and brush the inner part of the open female flowers with it. This will pollinate them. You may notice there are more flowers open in the morning and this is the best time to do it.
BTW you can eat the flowers too, raw with a salad or fried in a bit of olive oil. Have a munch on one straight of the plant and see if you like the flavour. Don't eat a bee!

The secret is the soil.

I had this problem for a couple years. I would try to grow one or two plants and they would eventually shrivel up. The thing is they need pollination. My solution was to plant about 6 plants and I have tons of zucchini now! I like to make a really yummy zucchini bread and freeze it and I like a chocolate zucchini cake too. I also grill the little ones!
Another pointer: make sure to pick them often because they stop producing for a while if the flowers fall off the fruit. In fact they always seem to produce in waves.

Ok I will gather it and post at recipes.
