Question
whole tree
I believe it is a birch tree of some sort. Is is dripping like raindrops. Why? Do I need to do anything to it? I am attaching whole tree pic, I also have pics of trunk, drops on driveway and close-ups of leaves, but don't know how to send more than one.
AnswerSounds like aphids. These small insect suck the plant juices from the twigs and leaves and secrete a substance called honeydew which is high in sugar content and sticky. Control the aphids and the honeydew will stop.
I would either spray the foliage (both sides and the stem) with Orthene or treat with Bayer Advanced Tree and Shrub Insect Control. Both are systemic and will be absorbed by the plant and kill the insects as they suck the plant juices. Orthene is sprayed on the foliage and the Bayer product is applied to the soil around the tree and the roots will absorb the insecticide and transport it to the leaves and twigs killing the insect when it feeds on the juices. The Bayer will last longer and will not need to be applied again until next spring. The spray will need to be applied at least twice to insure all are killed.
Here is the web link to more information the Bayer product. Both can be purchased at your local nursery. http://www.bayeradvanced.com/product/Tree-Shrub-Insect-Control/concentrate.html
