Australian blocks have shrunk considerably while houses have grown, so most gardens now are courtyards, side passages, small backyards and balconies. Small spaces here are also harsher than large ones: walls and paving give off stored heat, and a courtyard can run several degrees hotter than the open garden on a summer afternoon. This guide works through the decisions in order: aspect, layout, vertical surfaces, pots, plant choice and the practical checks.
Step 1: Work out the aspect and what you want
| Aspect | Conditions in Australia | What suits |
|---|---|---|
| North-facing | Sunniest and hottest | Olive, agave, citrus in pots, rosemary |
| East-facing | Morning sun, afternoon shade, the gentlest | Almost anything; gardenia, camellia, ferns |
| West-facing | Brutal afternoon sun plus stored heat | Succulents and tough natives only |
| South-facing | Shaded, cool, often damp | Tree fern, clivia, xanadu, lady palm, mondo |
These are the reverse of northern hemisphere advice. If you have read that south-facing is the sunny aspect, that will cost you plants here. Then decide what the space is for: a place to sit, somewhere to grow food, a screen from the neighbours, or all three. The answer sets how much ground you give to planting and how much to paving and furniture.
Step 2: Plan the layout before buying anything
In a small space, the arrangement matters more than the plants. Keep one clear route through, put the seating where the shade will be at the hour you use it, and run the planting along the edges rather than through the middle. Our guide to garden layout mistakes that make outdoor spaces look smaller covers the arrangement errors that shrink a courtyard visually, which is worth checking before you buy anything. Choose furniture that folds or doubles as storage, and keep it off the beds.
Step 3: Use the vertical surfaces
Walls and fences are the biggest unused growing space in most courtyards. Climbing plants such as passionfruit, climbing beans or a flowering vine can be trained up wires or a trellis, and a green wall or a row of hanging baskets turns a blank fence into the garden's main feature.
- Star jasmine on galvanised wires covers a wall in two to three years, is fragrant, and comes off later without damaging render.
- Espaliered citrus or magnolia is productive or decorative in a 400 mm strip.
- An elkhorn fern mounted on a shaded wall is an Australian native using no ground space at all.
- Avoid climbing fig on rendered or painted walls; it attaches directly and takes the surface with it on removal.
Our guide to creating a thriving vertical garden compares pocket systems, modular panels and simple trellises, and explains which plants survive each one.
Step 4: Pots need to be bigger than you think
This is where small-space gardens fail most often. A 200 mm pot in full Australian sun can dry out completely between morning and evening. Use 400 to 500 mm minimum for anything significant, choose pale colours in sun since dark pots heat the root zone severely, group pots so they shade each other, and always empty saucers after rain. Our guide to choosing the right size pot explains how far to step up at each repot, and the plants for pots range is filtered to varieties that stay happy in a container long term.
Step 5: One good plant beats five average ones
In a small space, a single well-chosen feature, a lady palm, a tree fern, a compact crepe myrtle or a large agave, gives more than a collection of small shrubs. Repetition of one or two supporting species around it reads as design; one of everything reads as clutter. Choose plants at the scale of the space: our balcony plant picks and small courtyard garden ideas cover the varieties that hold their scale for years rather than outgrowing the space in two seasons, and the plants for small gardens range shows what is available in the right size.
Height without width
For screening a two-storey neighbour on a narrow block: Straight and Narrow lilly pilly holds about a metre wide at five to six metres tall, Capital ornamental pear reaches ten metres at two to three wide, and clumping bamboo gives six or seven metres in barely a metre of ground. Never running bamboo, which will travel under paving into neighbouring properties.
Step 6: Practical checks
- Call Before You Dig. Narrow urban beds usually sit over services.
- Keep vigorous roots away from slabs and driveways, figs above all.
- Check body corporate rules for balconies, including pot weight and drainage onto the unit below.
- Ensure airflow. Still humid corners in Brisbane and Sydney encourage fungal problems, so space plants rather than packing them.
- Plan for dusk: white flowers and silver foliage read in low light, and scent near seating earns its place twice.
By city
- Sydney: the smallest blocks and the most two-storey infill. Narrow screening is the priority.
- Melbourne: terrace and townhouse courtyards; frost pockets form in enclosed spaces on clear nights.
- Brisbane: heat plus humidity in an enclosed space. Airflow matters as much as shade.
- Perth and Adelaide: reflected heat off render plus alkaline sandy soil. Olive, agave and dietes are reliable.
- Canberra and Hobart: a walled space holds warmth and often grows what the open garden cannot.

Measure your space, decide how many pots it can carry, then choose plants to fit rather than the other way around. Browse our plants for balconies collection to get started.
