Serrano chili didn't produce any flowers or fruit
I planted 4 Serrano chilis. One plant is 5ft tall and about 3ft wide two more are 3ft tall and about 1ft wide. None of these plants have produced any flowers, or fruit, but looks as if they are going to seed. The little one which is about 1ft tall has just started to flower. I am clueless as to why the larger plants didn't flower, and just went right to seed. Any help would be awesome.
