Yikes, apparently things weren't already bad enough with my poor little tree... I took a good look at it today and it has scale insects on some of the branches!
Any advice for getting rid of them? A quick internet search found suggestions for using Neem oil, spraying with insecticidal soap, and scrubbing them off using insecticidal soap and a toothbrush. I'm thinking of trying that last option, but looking for opinions and suggestions
