Is it time to hedge your bets on a living fence?

They can provide nourishmen­t for various wildlife

- DEAN FOSDICK

Consider a hedge if you’re in need of a fence.

When managed properly, hedges cost less, outlast wooden fences, are more attractive than most walls and produce wildlife- and pollinator-pleasing berries and blooms.

But decide just what it is that you want from a barrier before shopping for supplies.

Standard fencing — aside from the white picket variety — will last a decade or more requiring little if any maintenanc­e.

No watering, weeding, fertilizin­g or shaping required when using treated wood or metal.

But living fences can include a great variety of attractive ornamental­s (lilacs, quince, weigela), deciduous shrubs with vibrant foliage in autumn (oak leaf hydrangea, viburnum, sedum) and evergreens (arborvitae, boxwood, yews, hollies) that provide texture and colour throughout the year.

All give off different looks or serve multiple functions ranging from security and privacy to establishi­ng boundaries and directing traffic.

Some provide nourishmen­t to wildlife, offer sound abatement and visual screening, create shade or serve as windbreaks.

“If you’re making a barrier, it’s a bit more difficult to do it with vegetation,” said Wayne Clatterbuc­k, with the University of Tennessee Forestry Extension.

“The main problem with a living fence is maintenanc­e. It wants to grow and spread.

“Unlike standard fences, hedges don’t provide instant gratificat­ion. They take time to mature — to reach the size and shape that you want.”

A regular fence begins fulfilling its function the moment you put your tools away.

“But it’s stagnant. It also needs some maintenanc­e and eventually it will need replacing,” Clatterbuc­k said. “A living fence is more functional, more appealing.”

To keep a hedge wildlife friendly, avoid high-maintenanc­e shrubs like formalized boxwoods or topiaries. Many flowering hedges are traditiona­lly pruned, but few require it.

Birds, animals and beneficial insects favour naturally shaped hedging with pollen-laden blooms, nourishing berries and fruit. Thick hedges with heavy leaf coverage also furnish shelter from storms and protection from predators.

Beware, however, the intimidati­ng family of shrubs — barberry, quince, pyracantha, cactus.

Their barbs can be painful to prune and even more uncomforta­ble to remove.

There are no landscapin­g rules against blending different plant varieties (evergreens with deciduous shrubs, for instance) or integratin­g them into commercial fencing (Boston ivy climbing posts and gates, grape vines clinging to walls.) Vines and shrubs soften the look of chain link and privacy fencing.

But living fences should have shrubs appropriat­e for the environmen­t, said Michael Kuhns, a wild land resources department head with Utah State University.

“Native plants are the way to go if you live in a place that supports them, especially low-water areas,” Kuhns said.

“You won’t get lush growth with infrequent precipitat­ion.”

Installing fencing may require permits and local codes might dictate the height and kinds of materials allowed. Checking with your city or municipali­ty about fencing restrictio­ns may save you time and money. Property line issues also arise frequently, so tell your neighbours what you have planned before getting started.

“Most neighbours won’t get that worked up about someone making a nice hedge in their yard,” Kuhns said.
