Why do my zucchin plants hold flowering and never bring back any zucchini on them?
i'm pretty sure you need to pinch off the flowers earlier it will bear fruit (in this case, vegetables). same is true for tomatoes. someone correct me if i'm wrong. this is how we've done it for generation in my family. Check your PH rank in the soil.Get a home test tools and check the soil.If the Ph level is to high or to low you will not ever procure any zucchini.
Zucchini and adjectives squash plants produce 2 types of flowers, males and females. Only the female blossoms will bear fruit. There are not mannish and female plants, each plant will produce both types of flower. My zucchini seem to make male flowers first and after starts making female flowers. Be patient. You will soon hold more zucchini than you know what to do with. i have never hear of pinching off the flower on any vegetable plant, and mine have other produced vegetables, i know that if you use a fertilizer BEFORE the plant produces the flower, they usually will not produce any vegetables.i have done that before i know any better and it ruined my garden.
Answers: Although there may be other reasons for zucchini plants not getting any zucchini, it's most possible that they just aren't getting pollinated.
If you examine the flowers closely & you see what looks like somewhat squash on it, you're actually seeing an ovary on a female flower...and something have caused it not to develop properly & it died off.
If you don't see those little ovaries...consequently you have male flowers which can't produce. Early within the season the male flowers usually appear before the feminine flowers appear on the plant.
Take a look:

Male flowers appear a week or two before the female flowers. Also, contained by periods of hot weather, the male flowers are far more numerous & the few feminine flowers that you do find may need help contained by getting pollinated. Sometimes there aren't enough bees or other pollinating insects around to pollinate the flowers.

Make sure you don't marine overhead early in the morning so the masculine flowers can have a chance to pollinate the womanly flowers.Male flowers are short lived. The flowers will open up before cock-crow and will close completely by mid-morning.The male flowers possess both pollen and nectar, the female flowers simply nectar. If the plants are watered from overhead early in the morning, that may prevent all further pollination for that day. Everything get washed off of the short-lived mannish flowers. Replacement flowers do not open then until the following morning.Pollination desires to be made to all segments of the feminine flower. This should be done by 10 a.m. because pollination carried out later than the end of the morning during reheat weather has very little kismet of success because the pollen will have heated up and fermented and will no longer be viable.
You should see the squash increase the day or two after pollination & it should be ready to pick within 3-4 days...unless your plant has squash bugs that intefer with the process by sucking the juice out of the developing squash.
This video shows how to hand pollinate your zucchini:

Also, there can be other reason why blossoms don't set fruit & fall off. Sometimes, even if they be pollinated... the blossoms can abort from the stress of high day and dark time temperatures. Extreme temperatures during flowering... below 55 degree or above 85 degrees... can reduce fruit set.
Plant disease, & even too much nitrogen can also impose poor fruit set. Too much shade or not enough light could own been a problem.
After all these considerations, it seem most likely that your plants failed to develop zucchini this precipitate in the season because the female flowers (if you have any) didn't get pollinated. When you get more feminine flowers & enough pollinators, you should see your plants producing.
Good luck! Enjoy the video :) Hope it helps.
