My Zucchini Start to Grow Then at the Blossom They Start to Die

Question

They are in a very large planter {livestock water trough}.

Answer 1

Poor pollination. . When the flowers are not properly pollinated, the plant will reject the fruit while they are just a few inches long. Hot weather will definitely contribute to this. However, you can try hand pollinating your plants. This article will help with that: https://www.gardeningknowhow.com/edible/vegetables/squash/pollinate-squash-by-hand.htm

Also, since it is potted, make sure to water twice as much in high temps.

Answer 2

Mine did the same thing earlier this summer. Old timers said it was too hot and dry. May try planting them where they get afternoon shade. That's what I will try next year.
