Watering

Consistently moist acidic soil, never allow root ball to dry out completely

Fertilizing

Acid-loving plant liquid feed every two weeks in spring and summer months

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. Red flower colours are best maintained by growing in slightly alkaline soil, though plants may become chlorotic in strongly alkaline soils. See shrubby hydrangea cultivation for more detailed advice
