Pia Hydrangea in Dappled Shade: When to Move, How to Water

Hydrangea 'Pia' Getting 6 Hours of Morning Sun — Is It Too Much?

Three 'Pia' hydrangeas planted on a south-facing Maryland site receive sun from 8:30 AM to 2:30 PM, filtered by two large sugar maples. They look "tired" but not wilted. Soil is clay, amended.

Assessment

• Sun: 6 hours of morning sun is acceptable — hydrangeas tolerate this if moisture is consistent.
• Tree competition: If maples are close, their roots steal water. Check distance.
• Clay soil: Holds moisture but drains poorly — amend with compost, mulch heavily.

Recommendation

If maples are >10 ft away, leave hydrangeas in place. Water deeply 2–3×/week in heat. Mulch 3 inches. If trees are closer, transplant to a shadier, moist spot this fall.

Afternoon Sun Defined

Midday to 4 PM — the most intense, drying period.
