I have been watering it as much as I can remember to do so which is every couple of days. What worries me is the difference between the branches in the front compared to the back. Green vibrant vs black bumpy dead-looking however still alive within the branch. I did cut back the concerning branches to the ground, they grew back normal looking and within a few weeks those bumps and dead tissue came back. If it is a fungus, how would I best treat it? Thanks!!!
