Why are my jalapenos turning brown? The plant looks healthy. The fruit turns brown after it is about inch and a half from tip to stem.

  • Could you upload a couple of photos, one of the plant and one of the peppers themselves? It could be a disease as suggested, or it could simply be that they're ripening.

It may be blossom end rot, does it look like this: http://www.caes.uga.edu/applications/publications/files/html/C938/images/Figure7.jpg ?

If it is, blossom end rot is caused by a lack of calcium to the plant.

  • Have you had your soil tested? It might show that you need to increase the calcium in the soil. There are plenty of organic fertilizers that are aimed for tomatoes & vegetables that will contain calcium.

  • Have you been over fertilizing with high nitrogen fertilizers?

  • Are you watering enough? Water is needed to bring the calcium up through the roots.

I have never had BER with peppers but with tomatoes I find it helps to pinch off the first few flowers of the summer to give the plant a chance to develop a good root system before attempting to support fruits. As suggested above good watering practices can also be a factor.
