Hydrangea paniculata 'Grandiflora'

How to grow Hydrangea paniculata 'Grandiflora' in NZ

Hydrangea paniculata 'Grandiflora' grows best in full sun or partial shade with fertile, moist, and well drained soil rich in organic matter. It performs particularly well in many regions throughout New Zealand and tolerates more sun than many other hydrangea varieties. Water regularly during dry periods to maintain healthy growth and flowering. Adding compost and mulch around the base helps conserve soil moisture and improve soil quality. Choose a sheltered planting site where the large blooms can be protected from strong winds during the flowering season.

Hydrangea paniculata 'Grandiflora' care tips

Hydrangea paniculata 'Grandiflora' benefits from regular watering during warmer months, especially while flowering and establishing. Apply mulch annually to help retain moisture and suppress weeds around the root zone. Feed with a balanced fertiliser during spring to support healthy growth and abundant blooms. Pruning is best carried out during winter or early spring by removing spent flowers and reducing stems to encourage strong new growth. This variety flowers on new season growth, making it more tolerant of pruning than many traditional hydrangeas.
