Watering
Maintain evenly moist soil, avoid full dryness and standing water
Fertilizing
Apply balanced liquid fertilizer biweekly through spring and summer
Pruning
Use the method for the hydrangea type: remove faded mophead flowers to the first healthy bud pair; paniculata and arborescens may have last year's stems shortened to healthy bud pairs. Climbing hydrangeas need overlong shoots trimmed after flowering. Most types are pruned in late winter or early spring; climbing hydrangeas are pruned after flowering in summer.
Propagation
Propagate by softwood cuttings in early summer or hardwood cuttings in winter
Growing
Grow in any moist but well-drained soil in partial shade or grow in sun if soil remains reliably moist. See shrubby hydrangea cultivation for further advice
