Which Way Does Your Balcony Face? Sun and Aspect in the Southern Hemisphere

Type “which balcony gets the most sun” into a search engine and most answers you’ll get are wrong — for us. They’re written for the northern hemisphere, where the sun tracks through the southern sky. In Australia it’s the reverse: the sun crosses the northern sky, so north-facing is the prized sunny aspect and south-facing is the shady one. Every plant decision on a balcony starts from that fact, and plenty of dead plants trace back to advice that had it backwards.

Find your aspect in ten seconds: open the compass app, stand facing out over the railing, read the bearing. Roughly 315°–45° is north-facing, 45°–135° east, 135°–225° south, 225°–315° west.

North-facing: the jackpot

Sun for most of the day, all year — and, usefully, more direct sun in winter (when the sun is low in the northern sky and reaches deep under a balcony roof) with some natural relief in summer (when it passes high overhead). That winter-sun bonus is what makes north-facing balconies genuine food-growing real estate.

Grow: everything, essentially — tomatoes, capsicum, chilli, beans, herbs, dwarf citrus, flowering plants. Fruiting crops that fail elsewhere on the building succeed here. Watch for: summer heat load and fast-drying pots — the fixes (bigger pots, mulch, grouping) are in the pots guide.

East-facing: gentle morning sun

Direct sun from sunrise to around midday, then bright shade — the mildest useful aspect. Plants get their light before the day turns brutal, which in a Queensland summer is a feature, not a compromise.

Grow: leafy greens and Asian greens (which bolt or scorch in harder aspects), most herbs, ferns and foliage plants near the shaded end, strawberries, and salad crops nearly year-round. Watch for: overestimating the sun — “bright” isn’t “direct”. Fruiting vegetables will grow but crop lighter than they would facing north.

West-facing: the blast furnace

Shade all morning, then full sun through the hottest hours of the afternoon — arriving with stored heat radiating off warm walls and concrete. Summer afternoons on a west-facing balcony are the harshest growing conditions in this article; midwinter, the same aspect turns pleasantly mild.

Grow: the tough-and-thirsty-proof brigade — rosemary, chilli (which genuinely enjoys it), succulents and hardy natives suited to pots, pelargoniums, bougainvillea where there’s room. Cherry tomatoes can work with serious pot volume and daily summer water. Watch for: soft-leaved anything (lettuce, basil, ferns) frying in January; small dark pots cooking roots. Shade cloth or a movable screen over the worst hours widens your options considerably.

South-facing: the shade garden

Little or no direct sun in winter; in midsummer, when the sun rises and sets well south of east and west, early and late slivers of direct light. Otherwise: bright, open shade. You will not grow tomatoes here — but shade gardens are a legitimate and good-looking genre of their own.

Grow: ferns, philodendrons and monsteras, peace lilies, bromeliads, orchids under cover, mint and parsley (the most shade-tolerant of the common herbs), and winter lettuce in the brighter patches. Watch for: buying sun plants on impulse; wind, which on many southern exposures replaces sun as the main stressor — the balcony guide covers wind defences.

Refinements that change the picture

Balcony depth and the roof above shift everything: a deep roofed balcony pushes direct sun toward the outer rail only, while the winter-low sun penetrates furthest on northern aspects. Neighbouring buildings can delete hours of theoretical sun — the only reliable audit is checking the balcony at 9am, noon and 3pm on a day you’re home, once in summer and once in winter if you can. And glass balustrades pass light through to plants behind them; solid ones cast a permanent low shadow, which is worth knowing before you park a pot in it.

Aspect isn’t destiny — it’s a briefing. Match the plant list to the light you actually have and every aspect, including due south, grows something worth having.

Balcony Gardening in Australia: The Renter-Friendly Guide

A balcony garden in Australia fails for one of four predictable reasons: the pots were too small for our heat, the aspect was misjudged, the wind was ignored, or the setup annoyed the neighbours below. All four are avoidable before you buy a single plant — and none of them requires drilling a hole or risking a bond.

Constraints first (it’s the renter’s superpower)

Before plants, three checks:

Weight. Wet soil is heavy — a large pot can weigh as much as a person. Balconies are engineered with limits, so keep serious weight near the building side rather than the outer edge, favour several medium pots over one enormous one, and use lightweight potting mix (never garden soil, which is heavier and performs worse in pots anyway).

Water runoff. The fastest way to a dispute is dirty pot water raining on the balcony below. Every pot gets a saucer; watering happens slowly, until the saucer just catches the excess and no further. It’s also worth checking your building’s rules — many schemes have by-laws about what can sit on, hang from, or drip off a balcony. That’s a check-your-scheme point, not something any website can answer for you.

Attachment. Nothing that drills, screws or glues. Freestanding shelving, railing planters that clamp (where by-laws allow), and heavy pots that simply sit are all bond-safe and take the garden with you when you move.

Aspect: the make-or-break call

Which way your balcony faces sets what you can grow, and in the southern hemisphere the sunny side is the north — the opposite of every American and British guide the internet will feed you. A north-facing balcony is prime edible-growing real estate; a south-facing one is shade gardening; east is gentle morning sun; west is afternoon blast-furnace that cooks soft plants in January. The full breakdown, including what thrives on each aspect, is in Which Way Does Your Balcony Face? — read it before buying plants, not after some die.

Heat and wind: the two balcony multipliers

Balconies are harsher than gardens. Concrete and glass store and reflect heat, so a 33-degree day is hotter in a west-facing pot than in any garden bed. And wind — the underrated killer — dries pots twice as fast as still air, shreds soft leaves, and tips top-heavy plants. Responses that work: bigger pots (more thermal and moisture buffer — pot size guidance here), mulch on top of the potting mix, grouping pots so they shade and humidify each other, moving the most delicate plants to the sheltered corner, and choosing tough plants for the exposed rail line.

Watering a balcony garden

Pots dry out faster than ground, and balcony pots faster still. The principles from our watering guide still apply — water deeply until it just reaches the saucer, then let the top few centimetres dry before going again — but expect daily attention in summer for small pots, which is itself the best argument for fewer, larger pots. Morning watering beats evening on a balcony: leaves dry quickly and less sits in saucers overnight.

A starter setup that works

For a first season on a typical balcony: three large pots (herbs you actually cook with; cherry tomatoes in the late-winter or autumn window; a lettuce-and-greens pot in the cooler months), one mid-size pot for something you love the look of, and a strict rule against buying more pots until these four are thriving. Small collections that thrive beat big collections that struggle — and they move house better, too.
