No landscape designer would ever create a dead-flat garden.

If you're starting out with one — newbuild homes often have them — and you keep it on one level, the blank canvas will inevitably become a bland one. Avoid the flat-as-a-board trap by letting your imagination soar skywards.

Add a decorative obelisk to give each border a lift in winter and grow sweet peas right up to the summit this summer. Cut across one corner of your plot with an arbour, fling a honeysuckle over it and give the garden a completely different viewing point.

By exploiting the vertical you detract from the humdrum horizontal, and you also create endless space for plants. Land might be limited but air is free.

Give the plain some perspective by introducing a generous arch. Introduce half a dozen, at regular intervals, and suddenly you have a rather romantic walkway — and endless possibilities for planting, from obligatory evergreen jasmine to frisky springtime clematis macropetala, or from a well-behaved climbing rose such as fragrant pink New Dawn to a highsummer baby pumpkin, sown from seed any time now.

If your garden is small, think large

One skimpy arch that you have to limbo through will have little impact. Don't be afraid to add a few bold exclamation marks — preferably green — such as a trio of pencil cypresses or slim-line junipers. Daring moves pay off: the garden, at a stroke, will look larger and a great deal more interesting.

Give the borders a physical lift — and make planting and maintenance a breeze — by converting them to raised beds and thereby changing the monotone one level to a visually livelier split-level. You can perch on the edges of the beds while you tackle the plants, and here and there, trailing plants such as prostrate rosemary, creeping thyme and Convolvulus sabatius can tumble extravagantly over the edges.

The vertical gardener sees even a drainpipe as an opportunity. Use yours to support pots of flowering plants along its length, with the help of plastic-coated steel rings that will grip the pipe and hold the pots securely (visit www.spanishrings.com).

The same principle will enliven a bare patio wall and bring your prize container plants to a more appealing eye level, so you look directly at them rather than downwards.

Bring in a multi-stemmed silver birch and you dramatically break up the tedium of a flat space; bring in two and you double the dynamism. Every garden should have at least one tree, however small the space. Consider a crab apple or an amelanchier; both deliver great fruit, flowers and foliage.

Keep the tree canopies high by cutting off the lower branches and you not only bring the eye up to a higher level, you let in more light so you can grow more plants beneath.

Spring's prettiest plants — pulmonaria, dicentra, erythronium — all thrive in the dappled shade of a deciduous tree and create a delectable mini-woodland. A highrise row of pleached hornbeam or fruit trees — order one ready-made from Clifton Nurseries (020 7289 6851) — provides a glorious green hedge on a higher plain. Bare-trunked, the trees are espaliered high enough to allow you to walk beneath them and they provide valuable screening from neighbouring buildings.
