How to pleach a michelia hedge

Luke Robertson • 7 June 2025

At EPIC Landscape Design, we believe in crafting outdoor spaces that are not only beautiful but also functional and reflective of your style. One of the timeless elements we often incorporate into our designs is the pleached hedge — a sophisticated feature that offers privacy, structure and seasonal interest. Stepping into our show garden, we’ve created a guide to trimming and training a pleached Michelia hedge.


What is a pleached hedge?

A pleached hedge is a “hedge on sticks”. Pleaching involves training trees to form a flat, connected screen above a clear stem. It's an elegant solution for creating privacy without sacrificing space, ideal for urban gardens in Christchurch and beyond. Want to block out your neighbours? This is the perfect solution!


Tools you'll need:

  • Sharp secateurs.
  • Pruning saw (for thicker branches).
  • Hedge shears.
  • Ladder (for taller hedges) – we strongly advise you ask someone to hold the ladder whilst you are using it.
  • Gloves and eye protection.


How to grow and shape your pleached hedge

Please note: this guidance is based on Michelia, but can be transferred to other plant varieties. Get in touch if you’d prefer a 1:1 on-site consultation.


Initial training

  • Once your Michelia has been planted, let it grow (image below of young trees planted). 



  • Once the new growth reaches 200-300mm, pinch off the tips (the most recent growth, see example images below) using your fingers. By pinching off the growth tips, this will encourage new growth further down the stem, creating a nice dense bushy plant. 

ESSENTIAL: make sure when tipping growth that you leave the central leader alone (the tallest stem) as this will ensure the plant keeps growing vertically.


  • Repeat this process several times over the growing season (spring to autumn) and potentially the following growing season. Image below shows young Michelia after pinching.



  • Trim off lower branches as required to start getting the bottom of the pleach growth in the correct position. Normally one layer of branches per year will keep the ratio of trunk to head correct.


  • After the initial tipping of the growth tips, you should have a nice and dense bushy tear dropped shaped tree (see example below).



Secondary training

  • Using your hedge shearers, trim the front and rear face of the trees to start creating the flat face of the pleached hedge. This will encourage the trees to start growing sideways.



  • Continue tipping the new growth on the sides so you continue creating a good dense pleach (see image outline below).
  • Once the desired height of your hedge is reached, it’s time to trim the central leader. This will further encourage more horizontal growth, filling the gap between the trees. See images below (the right image displays a flowering hedge during spring).

Final training

You’re almost there! After secondary training, your pleached hedge should be touching and you should have created a good visual screen.


  • With your cleaned and sharpened hedge shearers, trim your pleached Michelia twice a year to maintain a great and dense form. We recommend you trim your Michelia pleached hedge on either side of Labour weekend, or after flowering. This trim aims to tidy up the vigorous spring growth.


  • The next annual prune should be around Waitangi weekend. This will tidy up the summer growth and ensure your hedge looks good over autumn and winter.


ESSENTIAL: Ensure you trim your pleached hedge by early February, otherwise you will remove the flower buds for the following spring (see example before, during and after images below).



Maintenance advice

Maintain the base and trunk

Regularly remove suckers or unwanted growth from the base. Monitor for pests or diseases, especially in tightly interwoven branches, and keep the lower trunk clear to preserve the pleached appearance.


Regular trimming and pruning

Continue training and pruning each year to maintain the form and prevent overcrowding. Trim back soft growth, keeping the front and back vertical and the top flat. Remove any growth on the trunk below the pleached frame and cut back to 2–3 buds from the main structure to maintain density.


Feed regularly

Michelia are heavy feeders, especially during their prolific flowering period. We recommend fertilising them three times a year with a high iron fertiliser. Aim to feed in late winter to early spring, around Christmas and again in mid-autumn.

 

Tips for success

  • Select and plant appropriate trees: choose specimens that are suitable for pleaching. Ensure the branching is balanced and the trunk is straight. Plant them in a straight line, spacing them approximately 1.5 to 2 metres apart, or as specified in a planting plan (which we can design).


  • Begin training young: young branches are more pliable and easier to shape.


  • Interweave or espalier the branches: depending on your design preference, either interweave the young, flexible branches between trees to create a solid screen, or train branches horizontally in an espalier pattern along the support structure.


  • Ensure newly planted trees are well-watered until established.


  • Avoid over-pruning in the initial years; focus on shaping and training.


  • Consistency is key; pleached trees require annual maintenance to retain their form.


Incorporating a pleached hedge into your garden design can provide a structured, elegant backdrop that enhances your outdoor space's overall aesthetic (the image above is the street view of our show garden).

Autumn Leaves - EPIC Landscape Design Christchurch

Gardens are an important feature of any home, but many homeowners fall into the trap of concentrating on spring and summer flowering plants and shrubs to bring them joy. A well-planned garden should give you year-round satisfaction, and autumn is a season to enjoy a blaze of spectacular colours. Now is the time that you need to start planning your landscape design to introduce trees and shrubs for autumn colour. The Christchurch and Canterbury climate does not suit all types of trees and shrubs, so it’s important that you take advice before getting busy buying and planting. Here’s a selection of some easy to grow trees and shrubs that can brighten your autumn garden. These are just a few of the hundreds available, and we can talk about your many options during an EPIC landscape consultation .

Drought tolerant gardening is the process of landscaping or gardening that reduces or eliminates the need for supplemental water from irrigation. It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and is gaining acceptance in other regions as access to irrigation water is becoming limited. Plants whose natural requirements are appropriate to the local climate are emphasised, and care is taken to avoid losing water to evaporation and run off. The specific plants used in drought tolerant gardening depend upon the climate. Drought tolerant landscaping is different from natural landscaping because the emphasis is on selection of plants for water conservation, not necessarily selecting native plants. With recreation time at a premium, and a growing global concern for the supply of water, savvy gardeners and designers are adopting drought tolerant principles into every part of their landscape design. Until recently, drought tolerant plants and designs have most commonly been a feature around commercial sites, roundabouts and traffic islands. As water conservation awareness grows, drought tolerant landscape design is catching on – particularly in regions like Central Otago, Canterbury and wind windswept coastal areas of New Zealand. The trick to drought tolerance is choosing a landscape designer who can select plant species that are appropriate for your climate. Natives are an obvious choice, as they naturally grow in the local conditions, however, introducing exotic species into the design can achieve stunning looking gardens. A mix of native and exotic species will provide great contrast of colours and textures creating a more visually attractive design with more seasonal interest.

One of the most satisfying experiences we commonly come across is dealing with clients who admit they are not green-thumbed, however, by the end of the design and construction process, they have become inspired to learn how to maintain their new landscape to be the best it can be. But what should you have in the tool shed? It’s easy to go overboard when purchasing gardening tools and it can be overwhelming to walk into a hardware shop and know what to buy. So, to give you an idea of the essential ‘tools’ you need, we’ve put together a list of our top 10 essential garden tools you should look at purchasing to make your job easier. Tools can take up a lot space and cost a lot of money, but staying focused on the basics can keep your shed or storage area from becoming overcrowded. There’s always bigger and better; but buying the best quality tools that your budget will allow, and maintaining them, can go a long way in getting the most out of your investment.

As a landscape designer in Christchurch, Ligularia reniformis is one our our favorite plants to use as it provides stunning colour and texture to the garden. It does have one draw back which is winter but Don’t panic its totally normal for your tractor seat plants to suffer a little over winter. The frost is what has caused the damage and your plants will naturally grow back in the springtime. In their native environment these plants are winter dormant. The Christchurch climate is borderline for them and dependent on their placement at your property they will either hibernate over winter if they get frosted or too cold, if they are protected they will continue to look great all year round. If your tractor seats do get frosted its best to leave the burnt foliage on for as long as you can bear looking at it as it will provide some protection to the plant for the remainder of winter. In springtime cut the damaged foliage back to ground level and you will soon see the new growth starting to appear. Once you have cut the damaged foliage off we recommend applying a good 12 month slow release fertiliser and a child and pet friendly slug bait to reduce any damage which may occur.

With the arrival of spring, many people are starting to get their gardens and outdoor spaces ready for summer. The influx of warmer weather and a dry winter here in Christchurch has meant many gardens require regular irrigation to encourage growth and thrive in our drier climate. I am often asked by clients, how often should you water your gardens and lawns to achieve good growth and plant health.
