South-facing balconies are tiny pockets of sunshine and possibility — I’ve turned a narrow 1.5‑metre balcony into a productive, fragrant and low-maintenance spot by focusing on smart plant choices, right-sized containers and a few waterwise tricks. If your balcony bakes in the midday sun, this simple planting plan will help you keep things lush without daily watering or wasted effort.
Understanding the site before you plant
Before buying plants, I always map the light, wind and heat. A south-facing balcony typically gets the most intense sun from late morning through the afternoon. Surfaces like concrete or dark paint reflect extra heat, and winds can increase evaporation.
Take five minutes across a couple of days to note:
That quick survey guides container sizes, placements, and whether you need shade cloth or a trellis with climbers to moderate heat.
Choose waterwise, sun-loving plants
For me the goal is a mix of structure, flowers and scent — all from plants that tolerate dry spells. I favour Mediterranean and native perennials, drought-tolerant herbs, and a few annuals for colour.
Here are my go-to choices for a south balcony:
Container selection and soil mix
Size matters more than style for waterwise planting. Large volume containers hold more moisture and reduce stress between waterings. I aim for at least 20–30 litres for larger shrubs or small fruiting plants; smaller pots are fine for succulents and herbs.
My preferred soil mix is a fast-draining, moisture-retentive mix:
Add a slow-release organic fertilizer at planting — it reduces the need for frequent feeding while plants establish.
Smart irrigation: make every drop count
Waterwise doesn’t mean never watering — it means efficient watering. These are the strategies I use:
I water deeply and less often. Shallow frequent watering encourages weak roots; deep soaking encourages roots to seek moisture and makes plants more drought-resilient.
Layout and design for function and comfort
On a small balcony I use vertical space. A simple layout I often use:
Use lightweight materials for containers (fibreglass, plastic) to avoid overloading the balcony structure. I also group pots by watering needs — Mediterranean plants together, succulents in another cluster — so irrigation is easier and more efficient.
Seasonal care and troubleshooting

Common problems and quick fixes:
Planting calendar (example)
| Spring | Plant lavender, rosemary, salvias; repot succulents; install irrigation |
| Summer | Monitor water, mulch, deadhead, harvest herbs |
| Autumn | Prep for cooler weather, divide perennials, reduce watering |
| Winter | Protect tender plants, minimal watering, plan next season |
Finishing touches that make a difference
I always add a few sensory and practical details: a small ceramic tray of crushed lavender as a visual and scent accent, a folding chair that can be shaded in hot afternoons, and a watering can with a long spout for targeted top-ups. Solar LED string lights extend the space into evening without extra water or energy cost.
If you want specific plant lists tailored to your climate (Mediterranean, temperate, or continental), tell me your hardiness zone or city and balcony dimensions — I’ll suggest a compact palette and exact container sizes that fit your space.
