My Jaboticaba hasn't been looking good lately. I'm wondering if it's too dry here in Colorado for it to live. Do you think thats the case? I can send pictures if wanted.
Hey George - as a rule of thumb always post pics with questions like this. Its the first thing people will ask for. Really hard to help just by a written description.
Tell us a little more about this tree.
How long have you had it?
Does it stay in that window year round, how much light does it get?
How often do you water?
Do you fertilize?
Have you thoroughly checked the leaves and soil for pests?
Im not familiar with this species myself, but answering these questions on the front end will go a long way toward identifying the problem.
I had a similar problem with a jaboticaba a few years ago. In my case it missed a watering. It took some time to recover but it has. I don't keep it in full sun.
