I have a thriving Jalapeno plant in my greenhouse, and another 2 chilli plants. The plant is amazingly healthy, lots of flower and foliage but NO FRUIT!
Incidentally my tomato plants are very poor in yield as well, lots of flower drop there too. I wonder if the two problems are related?
I hardly ever watered the Jalapeno but in a fit of desperation I've started to give it some Phostrogen!
Any help appreciated!
