Water
Oakleaf Hydrangeas prefer consistently moist soil, especially during dry periods. Water deeply at the base of the plant when the top 2-3 cm of soil feels dry. Avoid overwatering, which can lead to root rot.
Mulching helps retain soil moisture.

Watering, pruning, propagation, and repotting details from plant data
Oakleaf Hydrangeas prefer consistently moist soil, especially during dry periods. Water deeply at the base of the plant when the top 2-3 cm of soil feels dry. Avoid overwatering, which can lead to root rot.
Mulching helps retain soil moisture.
Prune immediately after flowering to shape the plant and remove dead or damaged stems. Oakleaf Hydrangeas bloom on old wood, so avoid heavy pruning in late winter or early spring, as this will remove the flower buds for the current season.
Oakleaf Hydrangeas can be propagated by taking semi-hardwood cuttings in mid-summer. Dip cuttings in rooting hormone and plant them in a moist, well-draining medium.
Rooting typically occurs within several weeks in a warm, humid environment.
Repotting is generally not necessary for established landscape plants. For container-grown Oakleaf Hydrangeas, repot every 2-3 years in early spring into a slightly larger pot with fresh, well-draining potting mix to accommodate root growth.
