I haven't seen a lot or any bees to pollinate the zucchini flowers, as advised by D. Afford, how do we find recognise which is the make and female flowers to hand pollinate? This also happened to my strawberries, again, lack of bees.

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.
