Another garden failure for me are the hot pepper plants I bought. They've flowered but dropped without producing fruit. I was concerned as to why this was happening so I did a bit of investigation and found that the flowers of the hit pepper plants must be pollinated. Great!
Gardening on the balcony on a high floor makes it difficult for pollinators like bees and butterflies to help the plants with pollinations. I have seen a bee on two separate occasions but I do think they were impressed with the food source to tell their friends to visit.
So, I attempted to pollinate the hot pepper flowers with my finger. I don't know if that helped but I guess only time will tell.
