When I moved into a flat with a north-facing balcony, three separate people told me I could not grow vegetables there. What they meant, I later understood, was that I could not grow the vegetables — tomatoes, chillies, brinjal, the sun-hungry fruiting crops that dominate every beginner gardening list.
That turned out to be broadly true. What was not true is that nothing would grow. Over two years I have tested fourteen different plants on that balcony and kept notes on each. Some did genuinely well. Some survived without ever thriving. Four were outright failures.
This is that list, plus the thing I should have done before buying a single plant: actually measuring my light.
First: Measure Your Light Properly
"North-facing" tells you less than you think. My balcony gets direct sun from roughly 7:15 am to 10:30 am in summer, and from about 8 am to 10 am in winter when the sun sits lower and a neighbouring building blocks it earlier. That is 2-3.25 hours of direct sun depending on season. After that it gets bright indirect light until mid-afternoon, then shade.
Two flats along the same corridor have measurably different light because of how the adjacent building casts shadow. So general advice about compass direction is only a starting point.
Here is what I do now, and what I wish I had done first. Pick a clear day. Every hour from 7 am to 6 pm, step onto the balcony and note one of three things for the spot where you plan to put pots:
Direct sun — you can see a sharp-edged shadow of your hand.
Bright indirect — no sharp shadow, but bright enough to read comfortably.
Shade — noticeably dim.
Count the direct-sun hours. That number, not the compass direction, is what determines what will grow. Do it once in summer and once in winter, because the difference can be an hour or more.
Also note which hours. Three hours of morning sun is gentler than three hours of afternoon sun. Morning light is what I have, and it is generally kinder — less heat stress, less water loss.
What Grew Well (Recommended)
Coriander — Best Performer
Coriander was the surprise. On a full-sun balcony coriander bolts — shoots up a flower stalk and stops producing usable leaf — within weeks in Indian heat. On my low-light balcony it stayed leafy for far longer.
My best batch: sown in a 10-inch wide, 6-inch deep pot in mid-October. First harvest at day 27. I harvested continuously by cutting outer stems for eleven weeks before it finally bolted in late January.
Compare that to a friend's south-facing balcony where the same seed, sown the same week, bolted at week five.
What I do: sow thickly, keep soil consistently moist, harvest by cutting outer stems at the base rather than pulling whole plants. Sow a fresh pot every three weeks for continuous supply.
Spinach (Palak) — Reliable
Palak handled the low light well. It grows slower than in full sun but the leaves come out larger and softer, which I actually prefer.
Timeline from my log: sown early November, first harvest of outer leaves at day 32, continued harvesting for about nine weeks. Roughly 400 g total from one 12-inch pot.
The one problem: in monsoon, leaves developed fungal spots twice. Low light plus high humidity plus wet leaves is a bad combination. I now avoid sowing palak between June and September, and when I do water it, I water the soil and not the foliage.
Mint — Almost Too Easy
Mint is a shade-tolerant plant and it behaves like one. Mine has been in the same 10-inch pot for over a year, gets my three hours of morning sun, and needs cutting back regularly to stop it taking over.
Only real requirements: keep it consistently moist and give it its own pot, because the roots will strangle anything sharing space with it. I learnt that after it choked out a basil plant I foolishly planted alongside it.
Methi (Fenugreek) — Fast and Forgiving
Methi was the fastest thing I have grown. Sown from ordinary kitchen methi seeds in a shallow tray, first cut at day 22.
It is a one-or-two-harvest crop rather than a continuous one — I cut it about two inches above soil, get a second smaller flush, then resow. But 22 days from seed to plate on a low-light balcony makes it the best return on effort of anything I have tried.
Curry Leaf — Slow But Steady
My curry leaf plant is now in its second year. It grows noticeably slower than curry leaf plants I have seen in full sun — maybe half the annual growth. But it is healthy, produces enough leaf for regular cooking use, and has survived two summers and two monsoons.
Key things I learnt: it hates waterlogging (I nearly killed it in monsoon year one by keeping it too wet), and it drops leaves in cold weather and regrows in spring, which alarmed me the first time.
Lemongrass — Vigorous
Lemongrass grew better than I expected in low light. Started from a single stalk bought at a vegetable market, rooted in water over about two weeks, then potted. It has now filled a 12-inch pot and needs dividing.
Money Plant, Snake Plant, ZZ Plant — Effortless
Not edible, but worth mentioning for anyone whose balcony is even darker than mine. All three of these have grown steadily with no direct sun at all — I keep them at the shaded end of the balcony. They are the plants that make a low-light balcony look green while the edible experiments are between cycles.
What Survived Without Thriving
Basil (Tulsi and Sweet Basil)
Both grew, both stayed small and slightly leggy — stretching toward light with more stem and less leaf than they should have. Usable, but noticeably weaker than basil I have seen in brighter positions. Sweet basil in particular produced maybe a third of the leaf volume I would expect.
My conclusion: basil tolerates three hours but does not do well on it. Worth growing if you want it, but do not expect a bushy plant.
Green Chilli
This one is honest disappointment. The plant grew perfectly healthy foliage — dark green, no pests, no disease. Over five months it produced exactly four chillies.
Fruiting takes considerably more light than leaf growth. The plant was not unhealthy; it just did not have the energy budget to fruit. I kept it as a foliage plant for a while and eventually gave it to someone with a brighter terrace, where it fruited heavily within two months.
Spring Onion
Grew fine from kitchen scraps but slowly. Regrowth after cutting took about three weeks, versus the one week I have seen reported for brighter spots. Worth doing because it costs nothing, but not a reliable supply.
What Failed Outright
Tomato — Complete Failure
Two attempts, two failures. Both plants grew tall and thin, stretching for light, developed pale leaves, flowered sparsely, and set no fruit at all. The second attempt I gave it my brightest corner and it made no difference.
Tomatoes need six hours minimum, realistically more in a container. Three is not a partial result — it is a no.
Brinjal — Failed
Same pattern. Healthy-ish foliage, no fruit, eventually declined. Abandoned after four months.
Okra (Bhindi) — Failed
Germinated well, grew to about 30 cm, then stalled completely and stayed there for six weeks before I removed it.
Marigold — Poor
I expected marigold to be tough enough for anything. It grew but flowered very sparsely — maybe five flowers on a plant that should produce dozens. Another case of light being sufficient for leaves but not for flowers.
The Pattern in All of This
Looking at my two years of notes, the rule is clearly this: leaves need less light than flowers or fruit.
Everything that worked well on my balcony is grown for its leaves — coriander, palak, methi, mint, curry leaf, lemongrass. Everything that failed is grown for its fruit or flowers — tomato, brinjal, okra, chilli, marigold.
That is the whole heuristic, and it would have saved me about ₹1,200 in dead plants and seed if I had understood it in month one.
Three hours of direct sun is enough to run photosynthesis for leaf production. It is not enough to fund the much larger energy cost of producing flowers and then fruit.
Small Things That Improved My Results
Painting the wall behind the pots white. Reflected light matters more than I expected in a low-light space. My landlord allowed it and plants closest to the wall visibly did better afterwards.
Rotating pots weekly. Plants lean toward light. Quarter-turning each pot once a week kept growth more even and stopped the permanent lean I had on early plants.
Watering less than the general advice. Less light means less evaporation and slower growth, which means less water use. My pots need water roughly every 2-3 days in summer, versus daily for the same pots on a friend's south-facing balcony. I killed one plant early on by following a full-sun watering schedule.
Choosing wide, shallow pots for leafy greens. More surface area for sowing, and leafy greens do not need depth. A 12-inch wide, 6-inch deep pot outperformed a narrow deep pot for coriander every time.
Accepting slower growth. Everything takes longer here. My palak takes 32 days to first harvest where seed packets say 25. That is not a problem to solve; it is the condition to plan around.
If Your Balcony Is Like Mine
Start with methi and coriander. Both are cheap, both come from seeds you can buy at any kirana shop, both produce something edible in under a month, and both genuinely prefer the gentler light. That early success is what kept me going.
Then add mint and palak. Then, if you want a longer-term plant, curry leaf — accept that it will be slow.
And do not buy a tomato plant. I know the temptation; I bought two.
A Note on This Article
All of the above comes from my own balcony — north-facing, approximately 4 by 6 feet, in a north Indian city, with roughly 2 to 3.25 hours of direct morning sun depending on season. The timelines and yield figures are from my own written notes, recorded at the time rather than recalled afterwards.
Your balcony will differ. Even a slightly different building shadow or one more hour of sun changes what is possible — a friend with four hours on an east-facing balcony gets chillies to fruit, which I never could. Measure your own light before you buy anything, and treat any list like this one, including mine, as a starting hypothesis rather than a guarantee.
I write here about container and balcony growing specifically, which is all I have ever had space for — eight years across two cities and several balconies. If something in your conditions behaves differently, I would like to know: our contact page reaches me directly.
