Answer: It sounds as if you're keeping a close eye on the cultural requirements of your plant -- keeping it watered and fertilized. Have you noticed any problems with pests -- diseases or insects? One idea that comes to mind is a virus. I'm not sure if your particular variety is susceptible to tobacco mosaic virus, but a virus is one possible explanation for your plant suffering while one close by looks OK. Perhaps you can try pruning back a little more radically this early spring, and see if the new growth comes in any better.
