Mysterious drops of sweet liquid near oak tree
I have a 100-year-old oak tree that has never seemed ill or diseased. Today all over my garden in the vicinity of the tree I see big droplets of sweet liquid. It is the consistency and color of very light maple syrup, and is quite sticky.
I can't see where it might be coming from, but the droplets cover an area approximately 40' x 50'.
I'd appreciate any advice on how to determine if there is a problem I need to attend to.
