Bell Pepper Bloom Drop

sharigail(7)September 3, 2012

I'm getting really frustrated with my bell peppers. Out of 6 plants, all planted in different garden areas, I've yet to get close to a bell pepper. All of the blooms drop off after they bloom and start to fruit. Now that the weather is starting to cool again, I'd like to see if I can make a go of it. Any suggestions on how to keep the blooms on?

It is called 'Blossom Drop' and affects all fruiting plants, not just peppers. There is a FAQ here about it (linked below) and many discussions that the search will pull up using that term.

Primarily it is a pollination issue and caused by air temps making the pollen tacky and non-viable.

From the FAQ:

It may be caused by the use of excess nitrogen fertilizers or dry windy conditions, but the most common cause is temperature extremes. Tomatoes, peppers and beans are especially picky about the air temps when it comes time to set fruit. If the night temps fall below 55 or rise above 75 or if the day temps are above 90, the pollen becomes tacky and non-viable. Pollination cannot occur. If the bloom isn't pollinated, the bloom dies and falls off.

See the FAQ for more details.
