Q: Steve,

I have a tree-shaped ligustrum at the corner of my house that drops 30-40 leaves every day of the year. It's in full sun and is watered regularly. Otherwise, it seems healthy. Is this normal?

Thanks. Liz

A: I think you're dealing with the nature of the beast. Even leaves of broadleaf evergreens don't usually live more than a year, then they drop and are replaced by new leaves. If you live in a mild-weather area where plants basically grow year-round, you're going to see dropping leaves almost year-round. The only other cause I would look for is an infestation of some sort of sucking insect, like aphids or scales, on the leaves and stems.
