EXPAND YOUR GARDEN
(WITHOUT BUYING THE HOUSE NEXT DOOR)
Many of us have to make do with only a small area for gardening, but there are a number of techniques you can use to make your garden seem larger.
Use plants to make the garden appear larger
Dark colours make areas seem smaller and more enclosed. Using light colours will make an area seem larger and more open. So choose plants with light coloured foliage and flowers.
Combining light and dark foliage plants can create the illusion of depth. If you place light coloured foliage in the foreground and dark foliage in the background, the foreground will appear to be closer. The background will seem to move away, making the area seem bigger.
Plants with large leaves appear to be closer than they really are, just as plants with small leaves recede into the background. You can use this contrast to create depth in the garden. Use large leaved plants in the foreground and small leaved ones in the background and watch your garden expand before your eyes!

Design your garden to make it appear larger
Careful planning before you plant can make a big difference to the look of a garden.
KEEP IT OPEN
Avoid blocking out the sky. Use tall trees with open foliage, otherwise they will make the area seem very small in overcast or dull light. Deciduous trees are ideal for these situations.
Leaving areas open can also allow you to use the ‘borrowed landscape’ – the trees and plants from adjacent properties. But don’t make the garden too open. Plants are needed to screen off any nearby buildings and roads that spoil the look of the garden.
Solid plantings are more ‘enclosing’ than plants with open foliage, so avoid using ‘hedging’ type plants and select those that have less dense or even see-through foliage.
By hiding the harsh appearance of a wall or fence, the space within a garden can look larger. Plants such as climbers provide a softer visual screen than solid walls and fences. They disguise walls and fences without taking up too much space.
Small green foliage
Small white fragrant flowers
Autumn red foliage; deciduous
Orange Trumpet Vine
Brilliant orange flowers in winter
Traditional climbers for walls with various colour blooms
A garden will seem larger than it really is when you can’t see all of it at once. A simple trellis or a raised garden bed in the middle of a garden can divide up a garden into different areas or ‘rooms’. The effect can also be enhanced by using different types of plants or ground cover. For example, one area of the garden might have a paved surface with plants in terracotta pots, while the other side of a climber-covered trellis has a lawn area with a fish pond. By creating rooms with different styles or characteristics, you will also increase the potential uses for the garden.
