Firstly, let’s get our definitions straight. Essentially, the line which delineates one person’s property from another is called a boundary. Once inside a person’s property this definition of space is known as a division.

Boundaries serve the purpose of identifying ownership. But there is a lot more to them than that. Boundaries can also provide privacy, security, sound insulation and of course, be a thing of beauty. They don’t have to be structural either. Hedges or less formal mass plantings can both be effective boundaries that also serves the purpose of providing habitat for the local wildlife. How boundaries are defined tells us a lot about the owner. Does the boundary say “This is my place, keep out”, or does it send a message of welcome? Does it stand alone in its environment or does it blend in harmoniously, even borrowing elements from nearby properties?

In the fence shown here, this is a great example of a front boundary that really makes a statement. At the same time, it is providing an element of security.

If security or privacy are the reasons for defining your boundary – as is more commonly the case in the urban landscape – a high fence or wall is an obvious solution which would tie in with the neighbourhood. For a rural property with similar needs, this type of structure may be incongruous and could be softened by substantial plantings or replaced by wire fencing of a suitable height with thick plantings on each side. Keep in mind however, that a solid structure can create turbulence on the downwind side whereas an open structure such as a slatted fence or hedge will filter the wind, lessening the detrimental affect on garden plants.

Within the property, the divisions are made for many reasons as well. Play, entertainment and service areas are often delineated. Pets may need to be contained or livestock excluded. The classic front yard to back yard boundary of a 6 foot high fence with a gate instantly identifies the visitor’s domain from the private areas.

Private courtyards and areas for delicate plants are often bordered by dominating structures. The south side of these structures will always be in shade so appropriate plantings are required. Don’t expect to grow a lush green lawn there. Most divisions within a property can be defined by less obtrusive methods. This may be as simple as carefully selecting the materials used for a path or driveway or installing instead a low garden bed. YOu could get really creative and use elements such as an arbour, a hedge or even an expanse of water.

Fences used to define divisions are usually lower and open in structure. Unless the aim is to create specific rooms within the garden, plant selection can flow across these divisions creating a more cohesive result.

Pool fences are another division which need to be carefully considered. There are strict guidelines for their installation but this does not mean they have to be purely functional. Considering aesthetics with a good design will go a long way to giving you a lot more enjoyment from this investment.

For boundary fencing, two important factors you should take into account are your neighbours and the local council. Working with your neighbours prior to any boundary work will help avoid possible future disputes and as an added bonus, they may be willing to pay part of the cost. The council may also have restrictions on height, positioning or materials.

Although boundaries and divisions are only the lines between our outdoor spaces, they actually form an integral part of the garden landscape.
