Five Silver King Euonymus Losing Lots Of Leaves

Question

Planted five silver king euonymus shrubs last October. The shrubs have full sun, and are watered regularly. I noticed many leaves dropping off the shrubs this Spring. We sprayed with Sevin twice in last 4 weeks, and provided them with some plant food. Plants have stayed about the same. They have many leaves on the ground, and some small buds (cream in color, although the photos show them in yellow). Any thoughts on why this is occurring? We live in Northeast Georgia, Zone 8.

Those bright growths will be flowers! Likely, stress has brought them out in numbers.

I would check the pH and nutrient content of your soil before adding anything. These articles will help:

Stress from insect pests will be most common. Scale will be the usual culprit. There are many types, but all will adhere to your plant. This makes them difficult to kill.
