Watering

Fertilizing

Hydrangea feed in spring and again early 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 by hardwood cuttings in winter.

Growing

Grow in moist but well-drained, humus rich soil, in a lightly shaded spot with shelter from cold, drying winds. Mulch annually in spring. Soil additives may be required to maintain specific flower colours. See shrubby hydrangea cultivation for more detailed advice
