I have two zucchini plants growing well but they both have just a few flowers with bases that look like they are going to form a zucchini, and lots of flowers on long stems that don't look as though they could bear a zucchini. Should I pick these off or thin them out? Thank you for your time. Susan
Nope, those are "male" flowers and you need them if you want to eat zucchini! Female flowers are the ones that have the little round "things" at the base that will turn into fruit, but pollinators need the pollen from the male flowers (that hang out on long stems with no round things anywhere on them) in order to pollinate the female flowers... which will then produce zucchini! Here's an article describing the differences between the male and female flowers: https://www.gardeningknowhow.com/edible/vegetables/squash/female-male-squash-blossoms.htm
My zucchini plants have been infested with brown caterpillar like insects. The leaves and fruit are turning brown and rotting. Most of the plant is still healthy. What can I do to save it?
Neem Oil is a good treatment.
You can try picking off the caterpillars if they are highly visible to help out.

We planted zucchini plants and all was going well until a few days ago when we noticed some of the zucchini are starting to shrivel up and some of the ends are rotten. This happened last year and all the zucchinis died. What are we doing wrong? They do get enough water. Please help!
Blossom end rot is caused by a calcium deficiency.

I'm a first time gardener and have discovered that my zucchini has blossom end rot. It's just a few of the first ones to grow. One is very round, about three inches! Was just wondering if I could cut off the end and use it for zucchini bread?
Yes, you can cut away the bad end and use the rest of the zucchini.
Every year we have had abundant results with our zucchini plants. This year we are finding the flowers either gone or on the ground beside the bush. We have not had one zucchini this year. What could be causing this?
This first flowers that form on your plant are male blossoms. These will open and fall off of the plant. The female flowers come later and if they are not being pollinated will also drop off the plant.
You can try self pollinating your flowers.
