Almond Trees Have Sap On Them

Question From: G. Sanchez - Yuba City, California, United States
Q: Why does my almonds have sap on them? And does need to be controlled and if so how?

A: It may be honey dew produced by aphids. Look on the undersides of the leaves. However, I live in Michigan and have no experience with these trees. I recommend you get and onsite inspection from a certified arborist. To find one in your area go to and enter your zip code. Best And Happy Yardening, Nancy
