Can my hydrangea recover from losing all its leaves?

Yes, if the roots are still healthy, the plant can regrow foliage. Keep it in a stable environment and continue to water it properly.

Is it normal for my hydrangea to lose leaves in winter?

Bigleaf hydrangeas are deciduous and will naturally drop their leaves as they go dormant in the winter. This is a healthy part of their life cycle.

Why is my hydrangea dropping its leaves? Causes and fixes

Check these first

Check the soil moisture level immediately.
Look for signs of recent temperature changes or drafts.
Examine the fallen leaves for spots or pests.

Likely causes

Severe Dehydration
Most likely
How to tell: The leaves turn crispy or brown at the edges before falling off. The soil will feel bone dry and pull away from the sides of the pot.
What to do: Soak the root ball thoroughly by placing the pot in a basin of water for 30 minutes. Resume a schedule of watering every 2 to 4 days when the top inch of soil is dry.
Temperature Shock
Possible
How to tell: Leaves drop suddenly after a cold snap or a move to a drafty location. The plant may look otherwise healthy but sheds foliage rapidly.
What to do: Move the plant to a stable environment away from AC vents or heaters. Ensure it stays in a spot with consistent temperatures between 60 and 75 degrees.
