I've got some pepper plants...bell, japeleno, and similiar variety...?

Question

they are about 2 feet tall and been planted for 3 months....when will they produce a pepper? How will I know one when it starts??

Answer 1

First of all it has to flower before it can produce peppers.  That big and that long in the garden, you should be seeing some buds by now.  I have 3 varieties of bells, some jalapenos, and some habaneros, and they all currently have blooms.

No blooms could be a problem of nutrient deficiency.  Try a fertilizer that is higher in phosphorus (which encourages strong roots, and blooms)
