How Far Apart Should You Plant Annabelle Hydrangea?

When forming a hedge with Annabelle hydrangeas, spacing is crucial for both flower density and plant health. Ideally, Annabelle hydrangea hedge spacing should be between 80cm and 1 metre apart. This allows each plant enough room to reach their mature width (about 1–1.5 metres) without crowding, while still creating a seamless hedge effect. If you’re after an extra-dense look more quickly, you can space them a little closer (about 70cm), but give each plant enough air circulation to prevent disease.

Tips for Planting Annabelle Hydrangea as a Hedge

For the best results, follow these practical steps:

• Prepare soil before planting. Hydrangeas thrive in rich, well-drained soil—add compost or organic matter for a healthy start.
• Space your Annabelle hydrangeas at intervals of 80–100cm, measuring from the centre of each plant.
• Mulch well to retain moisture, suppress weeds, and keep roots cool.
• Water regularly, especially during their first growing season.
• Prune annually at the end of winter to encourage strong new growth and larger blooms.

Annabelle hydrangeas are tolerant of partial shade, but flowering is more prolific in locations with morning sun and afternoon shade.

Creating the Perfect Hydrangea Hedge

Annabelle’s spherical, pure white flower heads make a classic, elegant hedge or boundary in any Kiwi garden. For an extended flowering season or more colour, consider mixing in other hydrangea varieties. Explore favourites like Hydrangea Ayesha for unique mophead blooms, or vibrant Hydrangea Bloody Marvellous to add pink-red accents. If you love blue hues, Hydrangea Blue Deckle is a great choice, while Hydrangea Bridal Bouquet offers more classic, elegant flower shapes. For taller hedges, Hydrangea paniculata Grandiflora is superb and dramatic.
