Click on links below to jump to that question.
We have 10 Green spireEeuonymus. Two of them are losing their leaves. There is no sign of spores on the branches. They are smooth. Just the leaves are falling off. They both have different schedules with sunlight. One gets 4 hours of sun while the other gets 8 hours.Using a Water & PH meter the ph factor is right on the money as well as the Alkaline to acid ratio. Also the plants are moist. Any help of how to correct this situation will be appreciated.
It sounds like you may have a root related issue. I would check the plant for crown gall, which is a common disease for this plant. It may also be a form of root rot.

Neem oil may be helpful. Here is more information: https://www.gardeningknowhow.com/ornamental/shrubs/euonymus/euonymus-scale-treatment.htm
We have golden splash shrubs on our sidewalk and a small part of that shrubs show what seems to be crown galls. We cut off the affected stems, but concerned that they will spread to the rest of shrubs. What should we do?
Unfortunately crown gall can remain in the soil for two years, so you may not be rid of it for a while. Removing the affected stems as you did will probably slow the spread but not stop it. The only treatments are plant removal, or a biocontrol treatment option as mentioned in the second article below:
Why would any knowledgeable person plant this extraordinarily invasive species? I grew up in Northwestern Connecticut (the Berkshires) and our 2 Burning Bush shrubs not only thrived but reproduced abundantly; it was as incredibly invasive. Who would a put up with this marauder when there are so many appealing shrubs that are just as easy to grow?
Thanks for your thoughtful response. So you have my permission to plant Euonymus alatus if you want - I'll continue to hate it!
