Plant a Hedge Row, Not a Hedge

Posted by Russell Nursery in Design, Hedges, Plant Choices

(Plant lists at bottom of page)

Hedges, in one form or another, have existed since our ancestors gave up their foraging life style and settled down in permanent residences. Over the centuries loosely piled brush, stacked rocks, iron railings and rows of shrubs have been used to keep livestock safe and to clearly mark the boundaries of personal property. Most modern hedges consist of dense rows of uniform shrubs, shaped and sheared into a smooth, uninterrupted form. High maintenance, susceptible to disease and damage and sometimes dark and foreboding, they don’t contribute much more to the garden than would a green painted fence.

If visions of butterflies drifting, bees humming, and songbirds bursting forth with notes of joy are guiding your garden plans, a mixed hedgerow will deliver all this and more, all the while freeing you from the rigid pruning schedules required to keep those conifer soldiers in perfect formation.

A mixed hedgerow is simply an assortment of shrubs or small trees planted relatively close together to form a row, which may be straight or curved, and, like an evergreen hedge, may provide privacy, wind protection, delineation of the property boundary, or even separation of one’s garden into “rooms”.

Ideally, a hedgerow is a mix of deciduous and evergreen natives and non-natives of various sizes that, combined, will contribute texture, shape, contrast and colour to the overall garden scheme. It will provide food, protection from predators, nesting sites and shelter from the elements for birds, bees, frogs and other creatures, which will in turn feast on damaging insects, slugs and weed seeds.

Native shrubs are especially welcoming to wildlife and are, by definition, well suited to our local conditions, being exceptionally insect and disease resistant. As well, native varieties require minimal pruning, fertilizer and water. Deciduous members will share their decaying leaves with the earth, and allow sunlight and breezes to pass through, while moderating the cold blasts of winter. If diseases or pests do attack one plant, the likelihood is that its neighbour, belonging to another species, will not be affected. Hedgerows need minimal pruning – the occasional thinning cut, the removal of wayward or dead branches and maybe a little cutting back and you’re done.

For a hedgerow to be successful, “right plant, right place” must apply to all plants chosen, and the plants must be able to live in peace and harmony with each other, enjoying the same soil, light and water conditions. As many or as few different plants as desired may be included. Choose a mixture of native and non-native, deciduous and evergreen shrubs that naturally grow to the desired height. Plants that have berries, fruits or seeds are particularly desirable. Even a vine or two, such as honeysuckle and clematis, may be included to amble along the row. Don’t put all evergreen shrubs together, but space them randomly as anchors and repeat each variety of shrub throughout the row in a non-predictable manner.

The plants should be placed 3 or 4 feet apart. The idea is to have them grow into each other, branches intermingling. If you have the space, a width of six feet or more is ideal for wildlife habitat. A row of smaller plants can supplement the principal row. The beauty of hedgerows is that they merge with additional plantings in garden beds, with no clear line between what is the hedge and what is the border.

Traditionally, hedgerows include such things as hawthorn, wild roses, mock orange, raspberries, hazelnuts and many more. Non-traditional shrubs like berberis, buddleia, camellias, Mexican orange, flowering currant, blueberries, laurels, lilacs – really almost any multistem shrubs, can combine to create a dynamic, living fence that changes with the seasons and adds immeasurably to the overall garden.

Below are two lists, non-native and native plant suggestions for hedgerows.
