Will my hydrangea grow leaves back?

If the stems are still green and flexible, the plant will likely recover and push out new growth. If the stems are brittle and snap easily, the plant may have died back to the roots.

Does leaf drop mean my plant is dying?

Not necessarily, but it is a sign that the plant is struggling to survive its current environment. Address the water and light issues immediately to help it stabilize.

Why is my hydrangea losing its leaves? Causes and fixes

Check these first

Feel the top inch of soil to see if it is bone dry.
Check the location to ensure it is not getting harsh afternoon sun.
Inspect the leaves for signs of spider mites or aphids.

Likely causes

Extreme Heat Stress
Most likely
How to tell: The leaves wilt during the day and may turn crispy or brown at the edges before falling off. This happens when temperatures stay above 85 degrees for several days.
What to do: Move the plant to a spot with more afternoon shade. Water the base of the plant deeply every morning to keep the soil consistently moist.
Severe Underwatering
Possible
How to tell: The soil pulls away from the edges of the pot and the leaves feel brittle. Hydrangeas are thirsty plants that cannot handle long dry spells.
What to do: Soak the entire root ball by placing the pot in a basin of water for 30 minutes. Resume a schedule of watering every 2 to 4 days.

When to worry

If the plant drops all its leaves in mid-summer, it is in serious trouble. It is normal for a few older leaves at the bottom to yellow and drop as the plant focuses energy on new growth.

Stopping it coming back

Keep the soil consistently moist and provide a layer of mulch to help the roots stay cool.
