we lived in ghana some years back, try to avoid rainy season as they can get moldy if humidity is high. otherwise most of the year.

If you want success in growing your zucchinis they will be need a lot of water. Water 2-3 times daily to ensure best results, soak the plant for 10-15 minutes each feeding session and you will be growing zucchinis like rabbits breed.

It could also be lack of water - zucchini is really thirsty.

It is the lack of bees, you need to pick the male flowers and rub them on the female ones. Hand pollinating. It works for me!
