Why are my Flowers falling of the zucchini plant?

Over pollination: Too much pollination can cause damage to the flower and cause it to fall off.

Poor nutrition: Zucchini plants need a range of nutrients to grow and produce flowers. If they don't get the nutrients, they need, the flowers may fall off.

Water Deficits: Lack of water can cause flowers to wilt and drop.

Heat and Drought: Zucchini plants perform optimally in temperatures ranging from 65-75°F (18-24°C) and require consistent moisture

Poor quality seeds: Zucchini seeds can come from different quality origins, and seeds of low quality might result in weak plants with flowers that are prone to falling.

Disease or Pests: Pests such as aphids, spider mites, and whiteflies can damage the flowers, causing them to drop. Diseases like powdery mildew and blight can also cause the flowers to fall off.

Weather conditions: Extremely hot, cold, or windy weather conditions can cause the flowers to drop off.

Too much fruit: If the zucchini plant is already producing a lot of fruit, it may drop some of its flowers to focus its energy on the existing fruit.

Plant overcrowding: When zucchini plants are too crowded, they may compete for nutrients and water, leading to the formation of fewer and smaller flowers that may drop.

Lack of Sun: Zucchini plants require at least 6-8 hours of sunlight per day to thrive and produce flowers.

Harvest timing: Zucchini flowers have both male and female components, and the female flower's petals can wilt prematurely if the male flowers are not present or harvested as soon as they begin to open.

Flower abortion: In some cases, zucchini plants may naturally abort some flowers as a way of regulating fruit production.
