Likely causes
Summer Dormancy
Most likelyHow to tell: The plant drops leaves during the peak of summer heat as a natural survival strategy. The stems remain firm and healthy.
What to do: Do nothing, as this is a natural process. Simply ensure the plant is not being overwatered in an attempt to force it to stay green.
Extreme Drought
PossibleHow to tell: Leaves are turning crispy and falling off rapidly during a heatwave. The plant looks brittle and dry.
What to do: Give the plant a deep, slow watering to help it through the extreme heat. Apply a light layer of mulch around the base to keep the roots cool.

When to worry
Shedding in summer is normal. If the plant drops all its leaves in spring or winter, it is likely suffering from root stress or disease.
Stopping it coming back
Provide consistent, light care and avoid drastic changes in your watering routine. Keep the plant in its preferred full sun environment.

- No, it is likely just entering summer dormancy to conserve water. It will flush out with new growth when the weather cools down.
- Should I fertilize to stop the leaf drop?
- No, never fertilize a stressed plant. California sagebrush is adapted to poor soils and does not need extra nutrients.
