I have been growing chilli plants for the last couple if years. In the first year I always get a decent amount of fruit considering the size of the plants. However, fairly consistently my chilli plants stop growing after their first season. They get to a certain height and just seem to stop. Some give up all together and just turn into sticks, others make it through the winter but then don't ever seem to get any bigger. I have seen chilli plants get quite large, a metre high or more, so I'm curious as to why mine are stunted.
I'm reasonably confident they are getting all the food they need and they always get plenty of water. So I'm wandering, what is the trick to getting large and plentiful chilli plants?!
