Why Courgette Flowers Fall Off (and How to Fix It)

Courgette plants often produce many flowers, and it can be surprising when some fall off without producing fruit. In most cases, this is a normal part of the plant’s growth cycle.

Courgette plants produce male and female flowers, and only female flowers develop into courgettes.

Understanding how courgettes flower helps explain why some flowers fall off.

Male flowers naturally fall off

Male flowers appear first on courgette plants.

These flowers produce pollen but do not grow into fruit.

After opening, male flowers usually fall off naturally.

This is normal and not a problem.

Pollination problems

Female flowers need to be pollinated to produce fruit.

If pollination does not happen, flowers may fall off.

Pollination is usually helped by insects like bees.

Warm weather often improves pollination.

Cold or wet weather

Poor weather conditions can reduce pollination.

Cold or rainy periods sometimes cause flowers to drop.

Plants usually recover once conditions improve.

Watering problems

Courgettes need steady moisture while growing.

Dry soil can stress plants and affect flowering.

Growing courgettes in containers

Courgettes can grow well in containers with enough compost and regular watering.

Courgette flowering is part of the growing cycle

Seeing flowers fall off is usually part of normal courgette growth.

Once both male and female flowers are present, plants usually begin producing fruit.
