Likely causes
Underwatering
Most likelyHow to tell: The leaves look limp and soft, and the soil feels dry to the touch several inches down.
What to do: Give the plant a slow, deep soak with a hose at the base. Ensure the water reaches 6 to 8 inches into the soil to hydrate the entire root ball.
Heat Stress
PossibleHow to tell: The plant droops during the hottest part of the afternoon but perks back up by evening.
What to do: Provide afternoon shade using a garden umbrella or shade cloth. Mulch around the base with 2 to 3 inches of wood chips to keep the roots cool.

When to worry
It is normal for hydrangeas to droop slightly on very hot days. Worry if the leaves remain limp even after watering or if they start to turn crispy.
Stopping it coming back
Keep a consistent watering schedule every 2 to 4 days and maintain a thick layer of mulch to retain soil moisture.

Questions people ask
- Should I mist the leaves when it droops?
- No, misting does not help the roots absorb water. Focus on watering the soil directly.
- Will my hydrangea die if it wilts?
- Usually no, as long as you water it promptly. Repeated wilting can stress the plant and reduce future blooms.
