Limelight Hydrangea Yellow Leaves: You're Overwatering

At planting: Deep soak.
First year: Once weekly (adjust for rain).
Established: Mostly rainfall; supplement in drought.

'Limelight' hydrangea (planted 6/18/09) flowering but leaves yellowing. Watered daily + new fescue sod. Cause?

Overwatering = Root Suffocation

Hydrangeas need moist, well-drained soil. Daily watering + sod irrigation = waterlogged roots → yellow leaves (chlorosis).

Stop daily watering. Let soil dry slightly between soakings. 'Limelight' (paniculata) is tough—it will bounce back.
