|I need to understand if pepper plants are perennials or annuals. Every book I have consulted is silent to the question. The answer would explain why my jalapenos are not producing peppers in my new greenhouse.|
|Pepper plants are usually considered annual plants. They produce fruit at the end of the summer when planted outdoors. Some people keep their pepper plants alive in a greenhouse throughout the winter. The plants won't grow much because of the reducedlight levels, but if you can keep them alive you can plant them outdoors in the spring and get a jump start on the season.
If the plants in your greenhouse are flowering but not setting fruit, it may be a lack of pollination. Try using a small camelhair paintbrush to transfer pollen from one flower to another and see if that doesn't solve the problem. But my guess is that there just isn't enough light this time of year. Keep them alive, and plant outdoors next spring when the weather has warmed up.
