Recommended Spacing for Griselinia Hedge Planting

The ideal spacing largely depends on the size of the plants you buy and how quickly you want your hedge to establish. For most hedging projects in New Zealand, spacing Griselinia plants between 75cm and 1m apart is recommended. This balance ensures your plants have room to grow vigorously while forming a thick, tidy hedge. If you want your hedge to fill out faster or prefer a more instant impact, you can plant Griselinia as close as 60cm apart.

Here’s a breakdown:

• 75cm to 1m apart: Best for a long-term, healthy hedge. Plants won’t compete for nutrients, which encourages strong growth and resilience.
• 60cm apart: Perfect for a quick privacy screen or formal hedge, but you'll need to monitor water and nutrition as the plants mature.

Factors Influencing Griselinia Spacing

While the general answer to "how far apart to plant Griselinia hedge NZ" is 75cm–1m, consider these factors before making your final decision:

• Varieties: Different Griselinia varieties can vary in growth habit. For instance, Griselinia littoralis is popular for its rapid growth and robustness, while Griselinia 'Ardmore Emerald' and Griselinia 'Whenuapai' offer refined foliage and upright forms—these can be spaced a tad closer for tight hedges.
• Height and ultimate size: If you plan to keep your hedge low, tighter spacing is fine. For taller hedges, wider spacing provides better air flow and root expansion.
• Site conditions: On exposed sites, closer spacing can help with establishment. For sheltered spots or fertile soils, you can space out a bit more.

Planting Tips for Griselinia Hedges

Proper preparation helps your Griselinia thrive. Dig a trench along the line of your hedge, mix in compost, and space plants carefully using a measuring tape. Water well after planting, and mulch to suppress weeds. Regular trimming keeps your hedge bushy and attractive. For a standout feature, consider alternating green and variegated forms, such as mixing Griselinia littoralis with the elegant Griselinia littoralis variegata (Variegated Griselinia). For unique regional flair, look for Griselinia 'Canterbury'.

Choosing the Right Griselinia Plants

New Zealand nurseries offer several standout Griselinia selections. If you’re after classic, reliable growth, Griselinia littoralis is the go-to. For a luxurious emerald presence, Griselinia 'Ardmore Emerald' is a favourite, while Griselinia 'Whenuapai' excels in coastal areas.
