Can you help identify the pests in this photo?
You have an impressive case of scale insects on your euonymus. Euonymus is quite prone to scale insects. If you want to keep the plant, cut it back by 1/3 now and dispose of the parts you are removing. Then use a systemic insecticide containing imidacloprid (Merit or Bayer Advanced Tree and Shrub insecticid

I have this plant in my back yard and was told by local residents that it was simply called a "Cat's Paw". It seems to prefer the shade of another tree. Any information you could provide would be appreciated.
Cat’s paw is a new name for me. The plant in question is a native shade loving deciduous shrub called Euonymus americanus. It has numerous common names including Strawberry Bush, Heart’s a bursting, and Brook euonymus. It thrives in moist areas in the shade. In late spring where you see these interesting fruits, it has fairly non-descript flowers in green. They are followed by these small fruits which turn pink in the fall and then pop open to expose dark red or orange berries, thus the common names
My euonymus will be two years old this spring. Several branches have developed a disease. The leaves turned a brassy color and some dropped off. Those leaves have black spots on the underside. The affected leaves are only on one of the shrubs but I notice the tips of several limbs on other shrubs have begun to wither. These affected limbs look as if they are trying to leaf out again. Is this Anthracnose and if so, how do I control it? If not, what is this and what do I need to do?
Some of the brassy color could be cold damage. I would also look closely at the underside of the leaves and the stems. The most common problem with euonymus is euonymus scale. It looks like someone sprinkled salt and pepper on the leaves and stems. These tiny insects suck the sap out of the foliage and can lead to dieback if not controlled. To be sure of proper identification of the problem, take a sample in to your local county extension office and they can send it to the disease diagnostic lab if they can’t identify the problem. Correct identification is the first step to control choices.
I am having a terrible time this summer with my golden euonymus. I have quite a few of them and don't want to lose them. Something seems to be sucking them dry. I have sprayed them twice with Malathion and it hasn't seemed to help. I have sprayed them with deer repellent too as we have quite a few deer eating them. I am at my wits end as to what to do. Can you please give me some advice?
My guess is you have euonymus scale. These tiny insects feed on the lower and upper leaf surface as well as the stems. It will look like someone poured salt and pepper on the plant. They suck the sap out of the plant and can weaken it considerably. But you should be able to see them. Malathion would give you limited control. A better option would be imidacloprid, commonly sold as Merit, Bayer Advanced Tree and Shrub Insecticide or Ferti-lome® Azalea/Evergreen Food Plus with Systemic. Prune off any heavily infested parts and then treat with the systemic insecticide. You can also wait for fall and spray the plant with a dormant oil, but the oil products must be thoroughly applied to be effective.
I need your advice! Several years ago my wife and I were in Pennsylvania and purchased two small bushes the locals call fire bushes. They seem to do well in that area and turned a brilliant burning orange/red in the fall. We transplanted these two shrubs in our yard in Conway and they have grown very large. A couple of problems we are having. This time of year they seem to start dropping all of their leaves so very little if any color appears in the fall. The other problem is that these bushes seem to be home to dozens of sparrows. Could the birds be the cause of the leaves dropping due to the birds taking up residence in them and all the defecating that is taking place? I try to make my yard a bird sanctuary by providing many bird feeders and bird baths. I enjoy my yard full of birds which unfortunately seem to be mainly sparrows but would also enjoy seeing these bushes in full fall color as we did in Pennsylvania. Any advice you could provide would be appreciated.
We seem to be having a lot of travelers to the New England area these days, all coming back with reports of the spectacular fire bushes—which we call burning bush. Euonymus alatus is the scientific name, and yes they do grow here as well. Fall color is often not as spectacular in the south as it is in the northern states, due to fall weather conditions, and sometimes summer stress. For ideal fall color, the plants prefer cool nights and warm days, ample soil moisture and a shift in the temperatures. Often our fall temperatures are still quite high, and the nights can be almost as warm as our days. I don’t think birds should be causing leaf drop, but do pay attention to watering needs. Don’t overdo it, but don’t let them shut down early because of dry conditions.
