I hope it’s okay for me to post this here! I have what seems like some sort of fungus on my Japanese Maple (poked with a stick, it seemed more fungus-y than insect-y.) There are many more of these higher up in the tree. Is it fixable??

    Not a fungus, but Cottony Cushion scale. Yes, it’s a bug. There are some natural controls that do a good job on keeping the numbers low. If you have something just covered with these critters, you can use Malathion or Orthene (according to North Carolina State University. Just make sure you follow all label recommendations if you go this route.

    I think it is important to mention that it is not always necessary to nuke every unwanted organism in the landscape. A good gardener knows that some bugs can be tolerated at low levels. The trick is knowing what can be tolerated, and at what level. In the case of the cottony cushion scale, let nature run it’s course, unless you have branches that are totally polluted.
