Philadelphus 'Boule D'Argent'

How to grow Philadelphus 'Boule D'Argent' in NZ

Philadelphus 'Boule D'Argent' grows best in full sun or light partial shade with well drained fertile soil and good airflow. Choose a sunny position to encourage strong flowering and healthy growth. Water regularly during establishment to develop a strong root system, then only occasionally once plants are established. Adding compost to the soil at planting time improves soil structure and moisture retention. Applying mulch around the base helps conserve moisture and suppress weeds while keeping roots cool.

Philadelphus 'Boule D'Argent' care tips

Philadelphus 'Boule D'Argent' is low maintenance and benefits from pruning immediately after flowering to maintain shape and encourage vigorous new growth for the following season. Remove older stems near the base to improve airflow and flowering performance. Feed with a balanced garden fertiliser during spring to support healthy foliage and abundant blooms. Water during prolonged dry periods, especially while young plants establish. Avoid heavy pruning during winter as flowers form on older wood.
