I live in south central nj and am in zone 7a. I have 3 plants with no pollen production. They were all container plants one of which I planted on the garden as my garden peppers are doing fine. They are the red moruga, butch t, and naga viper. The naga viper I planted in my garden maybe a week to ten days ago. The flowers on those plants seem a little brittle. On a side note I do have what appears to be BLS on those plants. The lower leaves are yellowing and dropping but the plants have maybe 2 foot by 2 foot canopys. I sprayed with Epsom salts 2 weeks ago and am trying out a fertilizer called trifecta plus and I was giving them compost tea during the heat wave we had a few weeks ago. I had blossom drop which i expected but the new flowers are completely devoid of pollen. This problem is only in my container plants (my container bhut plant is producing though) and all my containers are fed and watered equally. The plants are on my pool deck and get direct sunlight from 8-5. They were moved during the heat wave as the deck was getting so hot i was worried the roots would cook. I hope this is enough information to get started. I am on my mobile and this is my first post so I haven't figured out how to insert pictures yet.
