Hello,

I'm a bit overwhelmed. I'm fairly new to taking care of my backyard and gardening, and a lot of my plants seem to be getting sick or dying. This tree was doing very well until about 3 weeks ago. It survived a swarm of bees in the summer, and was home to a bird's nest for at least 6 months. Recently it began to loose leaves and now they're all falling. The photo on the left is from 12 days ago and the one on the right was taken yesterday. Anyone has any advice?
Thanks!
