Hedge Planting Spacing: The Key to Success

Getting hedge spacing right is the secret to a thriving, attractive boundary. Whether you want to mark a border, boost privacy, or add structure, how far apart you plant your hedges will shape their health, look, and lifespan. This guide makes it easy to choose the best spacing for every hedge type and purpose.

Why Getting Hedge Spacing Right Matters

Planting at the right distance from the start brings big rewards and prevents many common headaches:

General Rules for Hedge Spacing

Every plant is different, but these simple rules will help you pick the right distance for most hedges:

• Consider mature width: Most hedges should be spaced at 60-75% of their expected mature width.
• Purpose matters: Denser privacy hedges require closer spacing than decorative or wildlife hedges.
• Growth rate: Fast-growing species can be planted further apart than slow-growing ones.
• Patience vs. immediate impact: Closer spacing gives quicker results but may cause problems later.
• Plant size at purchase: Larger plants need more space than smaller ones of the same species.

Spacing Guide for Popular Hedge Types

Each hedge species has its own ideal spacing. Here’s a handy guide to the most common types:

Formal Hedges (Neat & Tidy)

For a crisp, gap-free look, formal hedges need to be planted closer together:

Privacy Hedges (For Screening)

To block views and create a living screen, use these recommended spacings:

Informal & Flowering Hedges

These hedges don’t need to be packed tightly—give them a bit more room:

A newly planted hedge with proper spacing will fill in to create a solid, healthy boundary.

Spacing Tips for Different Hedge Goals

Why you’re planting a hedge should guide how far apart you space each plant:

For Privacy Screening

• Plant at the closer end of the recommended range
• Consider double-row planting for maximum density (staggered pattern)
• Focus on species that naturally grow dense foliage
• For immediate privacy, use larger plants at appropriate spacing

For Marking Boundaries

• Standard spacing is usually sufficient
• Consider the legal implications of boundary planting
• Allow room for maintenance access on both sides if possible

For Decorative Hedges

• Can often be spaced more generously
• Consider the individual plant's ornamental qualities
• For topiary or formal designs, closer spacing may be preferred

For Wildlife-Friendly Hedges

• Mixed native hedges typically at 3-5 plants per meter
• Include a variety of species for biodiversity
• Consider slightly wider spacing to allow plants to develop natural forms

How to Plant for Perfect Spacing

Spacing is important, but so is how you plant. Follow these steps for the best start:

Single Row Planting

1. Mark out the line: Use string stretched between stakes to ensure a straight line.
2. Prepare the soil: Dig a trench 45-60cm (18-24") wide and 30-45cm (12-18") deep.
3. Improve the soil: Mix in compost or well-rotted manure to improve fertility and drainage.
4. Measure spacing: Mark planting positions at the appropriate intervals.
5. Plant: Position plants so the root ball's top is level with the soil surface.
6. Backfill: Fill around plants with soil, firming gently but thoroughly.
7. Water well: Give a thorough soaking to settle soil around roots.

Double Row Planting

Want a hedge that fills out fast? Double-row planting is the trick:

• Create two parallel lines 30-45cm (12-18") apart
• Stagger the plants in a zigzag pattern
• Use the upper end of the spacing range within each row
• This approach is particularly effective for privacy hedges and windbreaks

Caring for Your Newly Planted Hedge

Looking after your new hedge is just as important as planting it right:

• Watering: Regular watering for the first two growing seasons, especially during dry periods.
• Mulching: Apply a 5-7cm (2-3") layer of organic mulch around plants, keeping it away from stems.
• Weed control: Keep the area around new hedges weed-free to reduce competition.
• Feeding: Apply a balanced fertilizer in spring to encourage strong growth.
• Formative pruning: Trim lightly in the first year to encourage bushy growth from the base.
• Gap filling: Replace any plants that fail to thrive promptly to maintain even spacing.

Common Hedge Spacing Mistakes

Watch out for these typical errors when spacing your hedge:

If you realize your spacing is incorrect, it's best to address the issue early. For hedges planted too closely, you may need to remove alternate plants once crowding becomes evident. For gaps, consider adding additional plants or training existing plants to fill the space.

Need Help? Professional Hedge Planting Services

Most gardeners can plant hedges themselves, but sometimes expert help makes all the difference:

• For large-scale hedge planting projects
• When dealing with difficult site conditions
• If you require immediate impact with mature plants
• When specialized knowledge of particular species is needed
• If you lack the time or physical ability for the project

Hedge specialists know how to pick the best species, get the spacing just right, and plant for lasting results.

Final Thoughts

Spacing your hedge correctly is one of the most important steps for a healthy, beautiful result that lasts for decades. Know your species and your goals, and you’ll make the right call.

Don’t rush—hedges that are given a little extra space may take longer to fill in, but they’re usually healthier and easier to care for. With smart spacing, good planting, and proper care, your hedge will become a standout feature in your garden.
