Question of the Week Number 2: December 28, 2017
“Neil, why are my live oaks, azaleas and roses losing their leaves?”
I get this question a lot this time of year. We think of these plants as being evergreen in Texas, but in reality, they lose half or more of their leaves over the winter. It varies from plant to plant.
Most live oaks, for example, hold most of their leaves until late February or early March. That’s when they drop them and become almost totally bare for a couple of weeks while they gear up to start growing for spring.
Azaleas, roses, abelias and several other species of shrubs do the same thing, but they do so almost every year. Azaleas will drop half or more of their leaves, usually the oldest ones first. They turn yellow, and within a couple of weeks they’ll be on top of the ground. Rarely do the plants go completely bare.
All of this is completely normal and no major cause for concern. Take care that your plants are watered deeply during dry spells. Cover cold-sensitive types with frost cloth when extreme weather is forecast. Otherwise, don’t lose any sleep over it. They’ll be just fine come spring.
