Why do my leaves droop when it is cold?

The plant curls its leaves to protect itself from drying winds and freezing temperatures. It is a normal survival strategy.

How much water does a mature plant need?

A mature rhododendron needs a deep soak that reaches 6 to 12 inches into the soil. Aim for about 1 inch of water per week during dry periods.

Pontic rhododendron: drooping, causes and fixes

Check these first

Check the soil moisture with your finger.
Observe if the drooping happens only during cold snaps.

Likely causes

Dehydration
Most likely
How to tell: The leaves look limp and curl downward during a dry spell. The soil will feel dry more than an inch deep.
What to do: Give the plant a deep soak until water runs out of the root zone. Apply a 2 inch layer of mulch to help retain moisture in the soil.
Cold stress
Possible
How to tell: The leaves droop and curl tightly during freezing temperatures. This is a natural defense mechanism to reduce water loss.

When to worry
