What Grows Well on a Balcony?

The best balcony crops depend on measured light, wind exposure, container weight, and safe access—not balcony size alone.

It depends on two numbers

How many hours of direct sun the balcony gets, and how big a container you can safely place. Everything else follows from those. Count the sun at plant height across a clear day, and check what your building allows before assuming a railing planter is an option.

Under four hours

Leafy crops and tolerant herbs. Loose-leaf lettuce, spinach, chard, chives, parsley, and green onions all produce usefully here. Growth will be looser and slower than in full sun, which barely matters for a cut-and-come-again crop. Microgreens work in a sheltered corner but prefer being indoors.

Four to six hours

The leafy crops above, plus radishes, kale, and most soft herbs. This is a comfortable, productive range for a beginner and covers a large share of everyday kitchen use without demanding large containers.

Six hours and above

Now fruiting crops become realistic: compact tomatoes, peppers, bush beans, and strawberries. They want 25 to 30 cm of depth and around 20 litres of mix, so check the filled weight and the position before committing. Mediterranean herbs — rosemary, thyme, oregano — also want this level of light.

The balcony-specific constraint

Wind, not light, is what usually catches people out. Exposed pots dry far faster, tall plants rock and snap, and light containers eventually tip. Use heavier pots than you would at ground level, stake early, and put tall crops against a solid wall rather than an open railing.

Safety is part of the answer

Filled containers are heavy and that weight rests on someone else's structure. Keep pots on the floor rather than hung on rails, keep the walking route and any emergency exit clear, and know where drainage water goes before a neighbour finds out for you.
