Japanese Maple Disease?
We rent a home with a large, beautiful J.M. we just love. I've not seen this before...
I first noticed the table and chairs under the the maple's canopy are COVERED in something sticky. I looked in the tree and the leaves are covered in a shiny sap of some kind and there are thousands of small fly/gnat things all over the tree. Black bugs with sheer wings and the bugs barely move. Thousands!!
What could this be? I didn't find anything on Google, but I don't know what to search for.
The tree has a bed of wood violets below it, and was pruned in spring '06 (maybe '07). Not sure I can give any other helpful info..
