Question

I have a few young ceanothus shrubs in my yard. Their blooming period is now over, and now their leaves are turning yellow. What are the likely causes?

Answer

Newly planted Ceanothus still need some irrigation in their planting year. If you have them on a once to twice a week watering schedule, this is enough. Water once a week this first summer. Don't let the shedding leaves tempt you to water more often, this can lead to plant death. The yellowing and dropping leaves are a natural response to the increasing temperatures. The plants will shed leaves that they don't need to care for in the summer months. New leaves flush out in the fall.
