Bell Pepper Flowers Falling Off

Blossoms can drop if they don't get pollinated.  There are different ways to cause pollination to happen.  I use Aerogarden's Be the Bee pollinating tool but you can use an old electric toothbrush to gently "buzz" the blossoms.  Do a search on YouTube for "how to pollinate pepper plants" and you will find other methods such as giving your plants a gentle shake.  Khang Starr demonstrates this in one of his videos.  He also talks about other reasons for blossom drop.

By blossom, I meant the entire flower bud structure which includes the little stem, not just the flowering parts.  When there is no pollination, the entire flower bud falls off the plant.  

Are you familiar with Pepper Geek on YouTube?  He said in a video about flower bud drop that peppers sometimes overproduce buds and then drop some naturally.  I didn't know that.     His videos are also worth watching.  When you mentioned that the flowers fall off before the stems, I did a search to see if I could find more information about what causes that, but no luck.  Good luck with your pepper! 

gardengirl55, do you have any peppers at all developing on your plants? As katyag247 said, flowers will fall off if the pepper plant lacks energy to develop all of them.

All of the flowers and baby peppers dropped off one of my Poblano plants, when it was sitting in a warm draft from the furnace. Closing the furnace hot air register more or less fixed that problem.

However, what works best for me with peppers is to supplement the AG nutes with Koolbloom, which I learned about from mike. Koolbloom helps plants to produce blooms AND to hold the fruit that sets after pollination. You only need about 3ml of Koolbloom per gallon of water--and too much can cause blossom drop by shocking the plant.
