Balcony Garden for Beginners: 8 Easy Crops to Grow in Pots
A balcony gets more wind, more reflected heat, and far less soil than a backyard. That’s why most first attempts fail at the pot stage rather than the plant stage. Here are the 8 easiest crops to start with, the pot size each one needs, and a one-afternoon setup that costs roughly $60.
Your quick-start checklist
Do these five things and you’re already ahead of most first-timers.
- Pick the sunniest spot you have — most vegetables want 6 to 8 hours of direct light.
- Choose pots at least 10 in (25 cm) deep, with drainage holes in the base.
- Fill them with potting mix, never soil dug from the ground.
- Test the soil with your finger every morning and water until it runs out the bottom.
- Feed with a general-purpose liquid fertilizer every two weeks.
Rough cost of a 4-pot starter setup (US prices, September 2026): about $30 for pots, $12 for a 1.5 cu ft (42 L) bag of potting mix, $10 for liquid fertilizer, and $8 for three packets of seed. That lands at roughly $60.
What actually grows well on a balcony
Balconies are tough little microclimates. A south- or west-facing one bakes all afternoon, while a north-facing one may get only a couple of hours of weak light. Leafy crops handle that shade far better than fruiting ones.
Wind is the other factor. Pots on an upper floor dry out faster than pots on the ground, so bigger containers pay for themselves in saved watering. The RHS suggests aiming for containers at least 18 in (45 cm) deep and wide where you have the room. Cramped pots dry out quickly and need constant feeding.
The 8 easiest crops to grow in pots
- Salad leaves and loose-leaf lettuce. Ready to cut in about 30 days, and they regrow after you snip the outer leaves. Give them a wide, shallow pot and take a few leaves at a time.
- Radishes. The fastest payoff on this list, at roughly 25 to 30 days from seed. Sow a small pinch every two weeks so you’re not drowning in radishes all at once.
- Green onions (scallions). Happy in a narrow 6 in (15 cm) pot, and you can even start them from supermarket scraps. Snip the green tops and they keep coming back.
- Basil, parsley, and chives. One plant per 6 in (15 cm) pot is plenty. Basil wants your warmest, sunniest spot; parsley and chives shrug off a bit of shade.
- Spinach. A cool-weather crop that tolerates partial shade, which makes it a good pick for a north-facing balcony. Harvest young leaves often to keep it producing.
- Bush beans (dwarf French beans). No staking needed, unlike pole beans. A 12 in (30 cm) pot fits about six plants, and picking pods regularly keeps new ones coming.
- Peppers. Allow one 10 to 12 in (25 to 30 cm) pot per plant, in the hottest spot you have. They’re slow starters, so buy seedlings if you’re impatient.
- Cherry tomatoes. The one crop worth spending on: a 5 gal (19 L) pot minimum per plant, and choose a bush, patio, or tumbling variety. Stake it early, before the plant actually needs it.
Pot sizes and spacing at a glance
| Crop | Minimum pot depth | Spacing |
|---|---|---|
| Salad leaves and lettuce | 6 in (15 cm) | 2 to 6 in (5 to 15 cm) |
| Radishes | 6 in (15 cm) | 2 in (5 cm) |
| Green onions | 6 in (15 cm) | 1 in (3 cm) |
| Basil, parsley, chives | 6 in (15 cm) | One plant per pot |
| Spinach | 8 in (20 cm) | 4 in (10 cm) |
| Bush beans | 10 in (25 cm) | 6 to 8 in (15 to 20 cm) |
| Peppers | 10 in (25 cm) | One per 3 to 5 gal (11 to 19 L) pot |
| Cherry tomatoes | 12 in (30 cm) | One per 5 gal (19 L) pot |
Depth and spacing figures for salad leaves, green onions, spinach, and lettuce follow RHS guidance. The rest are the sizes I’ve settled on after a few seasons of pots.
Set up your balcony garden in one afternoon
- Check what your balcony allows. Renters should confirm pots are permitted and look up the weight limit, because a 5 gal (19 L) pot of wet mix weighs roughly 40 lb (18 kg).
- Buy or improvise containers. Five-gallon (19 L) food-grade buckets with holes drilled in the base cost about $5 each. Never reuse a container that held paint, oil, or pesticides — Clemson HGIC flags that as a real risk.
- Fill to about 1 in (2.5 cm) below the rim with potting mix. That leaves room to water without soil washing over the edge, which matters in a windy spot.
- Plant seeds or seedlings at the depth on the packet. Once seedlings have two or three leaves, thin them to the spacing in the table above.
- Water gently until it runs out of the drainage holes. This first soak settles the mix around the roots and removes air pockets.
- Add labels and pot feet. Pot feet or a couple of bricks keep the drainage holes clear and stop water staining the balcony floor.
Watering and feeding: the two things that decide success
Water is the make-or-break factor in containers. Clemson HGIC calls improper watering the number one reason container gardens fail. In summer, plan on watering once a day, and twice on hot or windy days.
Feed every two weeks with a general-purpose liquid fertilizer, which is the RHS recommendation. If your potting mix already contains slow-release fertilizer, every two to three weeks is enough. More is not better here — over-fertilizing burns roots, and a container has no soil buffer to absorb the mistake.
Two small habits help a lot. Group pots together so they shade each other’s soil, and push a finger into the top inch (2.5 cm) before watering. If it’s damp down there, skip it.
What didn’t work for me
Full-size tomato varieties in a 12 in (30 cm) pot were a bust — the plants set two fruit each and then sulked for the rest of the season. Carrots in a shallow pot forked and stayed tiny, so I grow radishes instead when I want a fast root crop. Mint planted alongside basil took over the entire pot within a season, so it gets its own container now. And terracotta looks lovely, but it dries out roughly a day faster than plastic, which matters if you’re away from home during the day.
A safety note if you have pets
The ASPCA lists the tomato plant as toxic to cats, dogs, and horses because of solanine in the foliage and stems. The ripe fruit itself is non-toxic, so the risk is mostly chewing on leaves. If you grow tomatoes, site the pots where pets can’t reach the foliage, and contact your vet or a pet poison helpline if you suspect ingestion. This is not veterinary advice — just a reason to think about placement before you plant.
