The complex i live in has 5 of these larger trees. They do not match any descriptions i can find of gum trees but they do "rain" a sticky gum all the time and their leaves drop all summer making a terrible mess. It is difficult to grow anything under them due to the gummy residue. I do not have any pics but the leaves are rounded at the top and come to a point at bottam. HELP!!!!!!
Don't have any idea for the id but the dripping is usually a sign of an insect infestation. For best answer, I would take a branch with some insect(Aphid?) damage on it to your local nursery or County Extension. To many possibilities to identify, although one of the experts here might have a guess. If you could submit a picture of a leaf, branch and tree you might have better success with an identification here. Harry
likely aphid residue that is the gummy stuff, nothing to do witha gum tree. any better description of the leaf? size, serrated or non edges.... color? alternate or opposite buds?
The leaves are are or less heart shaped, about 3 and half inches both ways. Whole clumps turn yellow and drop. All are sticky and adhere to everything within 10 or 12 feet.
