How to grow Hydrangea 'Flower Master Blue' in NZ

Hydrangea 'Flower Master Blue' grows best in a sheltered position with morning sun and afternoon shade, especially in warmer parts of New Zealand. Plant in fertile well drained soil enriched with compost to encourage strong root development. Keep the soil consistently moist during spring and summer to support generous flowering. Apply mulch around the base to retain moisture and regulate soil temperature. Protect from strong winds that may damage stems and blooms.

Hydrangea 'Flower Master Blue' care tips

Hydrangea 'Flower Master Blue' benefits from regular watering during dry periods to maintain lush foliage and vibrant flowers. Feed in early spring with a quality fertiliser for flowering shrubs to promote strong bud formation. Remove spent blooms after flowering to keep the plant tidy and encourage further growth. In late winter lightly prune by removing dead or weak stems while retaining healthy shoots that will produce the next season flowers.
