Hedges can be used to mark a boundary, edge a path or garden bed or screen out unwanted views. Hedging plants need to be evergreen (so they are green and leafy year round), suitable for clipping and robust. We've got all the know-how you need when it comes to selecting and planting low-maintenance hedge plants.

 

How to plant a hedge

To get the best from your hedge planting, prepare the soil ahead of planting by clearing out weeds and old roots and removing any stones. Break clumps in the soil. Dig in organic matter, such as compost or well-rotted manure.

Before planting, check the mature size of the selected plant. Allow room for it to grow in every direction and space the plants evenly in a straight line. Check your line is straight by setting up a stringline and use a tape measure or a measuring stick to evenly space plants. When spacing plants remember closer plantings create a faster hedge, while wider spacings mean the hedge will form more slowly, but the individual plants have more room to grow.

Water well at planting and regularly while the hedge develops and the plants become established. To make watering easier, consider setting up an irrigation system along the row of plants. Surround new plantings with a layer of organic mulch to help reduce weeds and keep the soil moist and cool. To encourage bushiness, lightly trim hedge plants as they grow.

5 best low-maintenance hedge plants

Here are five of our favourite hedge plants to suit a wide range of conditions. If named varieties are available, select these for your hedge to ensure uniformity of growth and colour. Always buy some extra plants (or propagate some yourself) so replacements are available if any initial plantings fail. These spare plants can be grown elsewhere in the garden or in containers.

Gardenia (Gardenia augusta)

Gardenia makes a dense, evergreen flowering hedge in a warm climate. ‘Florida’, the common florist’s gardenia, can be clipped to around 50cm-1m high and can be planted about 30cm apart for hedging. For a taller hedge select one of the large-flowered forms such as ‘Magnifica’ or ‘Professor Pucci’ and space up to 50cm apart. Gardenia flowers are white and highly fragrant. Prune annually after flowering in late summer to avoid removing flower buds. Expect spot flowering over many months in warm conditions.

Murraya (Murraya paniculata)

This shrub forms an evergreen hedge that can be maintained at around 2-3m tall. For a lower hedge (under 1m) select a dwarf variety. Murraya flowers in spring as temperatures warm, and after rain in summer and autumn with clusters of highly fragrant cream flowers. Pruning in spring may remove flowers. Space around 50cm-1m apart for hedging and keep well watered.

Photinia (Photinia ‘Red Robin’)
