Outdoor Hydrangea Wilting: Overwatering or Drainage Issue

Diagnosing Newly Planted Hydrangea Decline

Daily (or twice daily) watering on a newly planted hydrangea in possibly clay soil is likely overwatering/drowning roots. Wilting despite wet soil = root rot.

Questions to Answer

• Where do you live? (Climate zone)
• How hot has it been?
• Soil type? (Clay holds water)
• Did you amend the planting hole?

Immediate Steps

1. Stop watering. Let soil dry to damp.
2. Check drainage—dig gently near root ball.
3. If soil is heavy clay, consider replanting in raised bed or amended soil.

Hydrangeas need moist but well-drained soil. Constant saturation kills them.
