🌿 Griselinia Hedges – The Pros and Cons According to Tree Brothers

Looking for a fast, lush, and low-fuss native hedge that suits Auckland’s climate? Griselinia littoralis — commonly known simply as Griselinia — is one of New Zealand’s most popular choices for garden borders, privacy screens, and coastal planting.

At Tree Brothers, we plant, trim, and maintain hundreds of Griselinia hedges across Auckland every year. But is it the right hedge for your space? Here's our expert take on the pros and cons of Griselinia — plus tips on how to care for it sustainably.

🌱 What is Griselinia?

Griselinia littoralis is a hardy, fast-growing native evergreen shrub with broad, soft green leaves. Naturally found along NZ’s coastlines, it’s well-suited to urban gardens, rural properties, and lifestyle blocks alike.

It thrives in Auckland’s temperate climate and can be used for formal or informal hedging, shelterbelts, or green walls.

✅ Pros of Griselinia as a Hedge

✔️ Fast Establishing

Griselinia grows quickly once settled, giving you full coverage and privacy within 12–24 months depending on spacing and care.

✔️ Native and Low-Maintenance

As a New Zealand native, it’s well-adapted to our soils and climate. It generally requires less pest control and is more resistant to local weather extremes.

✔️ Dense, Lush Appearance

Its thick, glossy foliage gives excellent coverage, making it perfect for screening, wind protection, and sound buffering.

✔️ Tolerates Coastal and Windy Conditions

Griselinia performs well in exposed areas, including coastal suburbs. It’s one of the best choices for windy or salty environments.

✔️ Easily Shaped

Whether you like a natural look or a crisp edge, Griselinia responds well to regular trimming and shaping.

⚠️ Cons of Griselinia Hedges

❌ Needs Watering When Young

Griselinia isn’t drought-tolerant in its early stages. It requires consistent watering during establishment, especially through dry summers.

❌ Sensitive to Poor Drainage

It dislikes wet feet. In poorly drained soils, roots can rot — especially in winter. Proper planting depth and drainage prep is essential.

❌ Can Thin Out at the Base

Without regular trimming or enough sunlight, Griselinia may become top-heavy and sparse at the bottom.

❌ Vulnerable to Leaf Spot and Aphids

Although generally hardy, it can suffer from fungal leaf spots and sap-sucking insects if neglected or overcrowded.

Tree Brothers Tip: Good airflow and organic soil health go a long way in preventing common issues.
