How to make a small garden look bigger

A small garden is not a failed big garden. Some of the best spaces we see are a three metre courtyard in a townhouse complex or a balcony in a Pretoria block, and what makes them work is nothing to do with square metres. It is that somebody made a decision and stuck to it, rather than adding a little of everything until the space filled up.

Almost everything below comes down to two ideas. Give the eye fewer things to count, and give it further to travel. Once you have those in your head, most of the specific moves follow on their own, and you will find you are taking things out of the garden more often than you are putting them in.

One big pot beats five small ones

This is the change that makes the most difference and the one people resist hardest. A collection of small pots along a wall creates a busy, fussy edge, and the eye stops at every single one. A single large pot creates one confident shape, and the space reads as considered rather than crowded. Counterintuitively, the bigger pot makes the garden look bigger.

Go up in size rather than in number. Something in the sixty to eighty centimetre range placed at the far end of a small courtyard does more work than a dozen smaller ones scattered about. It also grows better, since a larger volume of mix holds moisture through a hot week and buffers root temperature. Our feature pots and bigger plant pots are made for exactly this role, and the size chart will tell you the true footprint before you commit. We wrote more about this in our piece on why a statement planter earns its place.

Repeat a finish so the eye stops counting

Variety is the enemy of scale. Three pots in three colours and three materials read as three separate objects, while three pots in the same finish read as one grouping. Pick a single material and a limited palette and hold the line, even where a different pot would have been tempting.

The same applies to the plants. Repeating one or two species along a run creates rhythm, and rhythm reads as intention. A different plant in every pot reads as a collection of individual specimens, which is charming in a big garden and chaotic in a small one. The NC State Extension chapter on landscape design sets out repetition and unity as design principles properly, and our article on balancing pot colours and shapes works through the practical combinations.

Send the eye on a diagonal

The longest line in any rectangle runs corner to corner, and a small garden that is laid out square to its own boundaries never uses that line. Turn your paving, your main planting bed or simply your seating so the primary axis runs diagonally, and the space instantly feels deeper because the eye travels further before it hits a wall.

Put something worth looking at at the end of that diagonal, since a line needs a destination. A single tall pot, a sculptural plant, a small tree in a container. If you can arrange it so that point is partly obscured from the doorway, better still, because a space you cannot see all of at once feels larger than one you can. The RHS garden design pages cover sightlines and focal points in more depth if you want to go further with it.

Build upwards

Floor space in a small garden is expensive, and vertical space is free. A trellis on a boundary wall, a climber trained up it, a tall narrow pot with an upright plant, a row of planters mounted at eye level. All of these add greenery without taking another square metre off the ground.

Layering matters as much as height. A low planting at the front, something mid height behind it, and one tall element at the back creates depth in a bed that might only be a metre deep in reality. Strappy, upright indigenous plants earn their place here. Wild iris is a good example, and the SANBI PlantZAfrica profile for Dietes grandiflora covers its habit and its tolerance of both sun and part shade, which is useful in a courtyard where light changes through the day. Our trough range works well along a boundary, and on a balcony the Lightweight Décor range gives you the same look where weight is a real constraint. There is more in our guide to the best pots for a balcony or patio.

Pale finishes carry the light

Small gardens are often dark, because a boundary wall two metres away blocks a great deal of sky. Pale surfaces bounce what light there is around the space, and a light coloured pot against a dark wall creates the contrast that gives a space depth. A dark pot against a dark wall disappears, and everything in front of it flattens.

The same trick works on the ground. A pale gravel or a scatter of white pebbles as a mulch lifts a shady corner noticeably, and it holds moisture in the mix underneath, which matters through a dry Highveld winter. Our pots are hand cast from our Fibre Concrete Mix, and the natural concrete tones sit in that useful pale to mid range that reads as light without looking stark. The Illinois Extension guide to container gardens is worth reading on how container colour affects both the look and the root temperature, which matters more here than in a cooler climate.

Keep the floor clear

How much of the ground you can see is one of the strongest cues the brain uses to judge the size of a space. A courtyard with a clear paved centre and planting pushed to the edges feels far larger than the same courtyard with pots dotted across the middle, even when the planted volume is identical.

So push things to the perimeter, lift what you can onto walls or shelves, and resist the urge to fill the middle. If you need furniture, choose one piece with presence rather than a set, and pick something you can see under or past. A single concrete coffee table or a bubble chair in a corner does the job without breaking the floor plane into pieces. Our patio and small garden favourites collection is put together with exactly this restraint in mind.

Mirrors and water, sparingly

An exterior grade mirror on a boundary wall genuinely doubles the apparent depth of a small courtyard, and it is one of the oldest tricks in the trade. It is also very easy to overdo. One mirror, placed off centre, partly obscured by planting so the reflection is glimpsed rather than announced, is the version that works. A mirror facing you square on at the end of a path just looks like a mirror, and birds fly into it.

Water does something similar and adds sound, which distracts from traffic noise and makes a space feel more enclosed and further from the street than it is. Keep the scale honest, since a large feature in a small courtyard is overwhelming. A bird bath or a compact piece from our water feature range is usually the right size, and the birds it brings in add movement to a space that might otherwise sit still.

Where to start

If you only do one thing, consolidate. Take out the odd assortment of small containers, choose one large pot in a finish you actually like, and put it at the far end of the longest diagonal you can find. Then live with the empty floor for a week before deciding whether anything else needs to go back. Most of the time it does not.

When you are ready to pick that one pot, our feature pot range is where we would send you, and if you want to test a shape against your space first, our free Garden Planner lets you work it out before anything arrives on the patio.

Frequently asked questions

Do big pots make a small garden look smaller?

No, the opposite. One large pot reads as a single confident shape, while a scatter of small pots creates a busy edge that the eye stops at repeatedly. Consolidating almost always makes a small space feel larger.

What colour pots work best in a small courtyard?

Pale to mid tones, because they bounce light around a space that is often shaded by boundary walls. A light pot against a dark wall creates the contrast that gives a small garden depth.

How do I add plants without losing floor space?

Go vertical. A trellis with a climber, wall mounted planters at eye level, or a tall narrow pot with an upright plant all add greenery without taking another square metre off the ground.

Do garden mirrors really make a space look bigger?

Yes, if used sparingly. One exterior grade mirror placed off centre and partly screened by planting adds real depth, while a mirror facing you square on simply looks like a mirror and can be a hazard for birds.

Should I keep the middle of a small garden empty?

Largely, yes. How much clear ground you can see is one of the strongest cues the brain uses to judge size, so push planting to the perimeter and keep the centre open.
