10 Vegetables That Do Well in Pots on a Balcony
A balcony changes the rules. You get wind, reflected heat from walls, and pots that can dry out by lunch on a hot day. You also get no weeds, no rabbits and no digging. The crops below were picked because they cope with a container, and each one comes with a pot size so you buy the right one the first time.
I grow on a sunny balcony myself, and the biggest lesson there was size. A tomato in a 2-gallon pot is a sad sight by midsummer. Bigger pots hold more water and swing less in temperature, which means fewer emergencies. Count how many hours of direct sun your balcony gets on a clear day before you shop. Six or more opens up the whole list, while four leaves you the leafy greens.

The big one, so give it a 10-gallon pot at minimum and a cage on day one. Compact or patio varieties make balcony life easier. A loaded plant drinks a lot, and a pot that size can still dry out in a heat wave, so plan on daily watering in summer.

Peppers like a warm, sheltered spot, and a balcony often is one. A 5-gallon pot is enough. In midsummer that pot may need water every day, sometimes twice in a heat wave. A saucer is fine, but empty it after rain so the roots do not sit wet for days.

A sunny balcony corner can feel like home to eggplant, which loves heat. Use a pot of about 5 gallons and push in a short stake at planting, since branches lean once fruit hangs. Hot, dry wind can make the blooms drop, so tuck it somewhere sheltered.

No trellis and no fuss. A 2-gallon pot holds a few plants, sown as seed after your last frost once the mix is warm. Hot spells above about 90 degrees F can make the flowers drop, and a balcony facing south can get there fast. Pods usually start again when it cools.

Shallow roots mean a 2-gallon pot or a window box is plenty. Lettuce gets by on about 5 hours of sun and likes the cooler ends of the season. In summer, move it to the shadiest corner you have, because heat and dry mix push it to bolt and turn bitter.

A 1-gallon pot and a few inches of mix will do. Arugula is ready in roughly 25 to 45 days and regrows after you cut it. Flea beetles chew tiny holes in the leaves, even several floors up, so check young seedlings and cover them with fine netting if needed.

Chard is the pot plant that keeps paying. A 5-gallon container holds a plant or two that you can pick from for months. It manages on 4 hours of sun, so a balcony with only morning light still works. Water deeply in hot weeks, since dry mix can push it to flower.

8Kale
Kale rates as great in pots and is happy in about 5 gallons of mix. It takes cold well, so a spring pot and a fall pot both make sense. Cabbageworms find balconies too. A piece of row cover tied over the pot keeps the white butterflies from laying eggs.

The smallest pot here, about a gallon, works for round varieties. Radishes make a good test for a new balcony, since you know within a month whether the spot gets enough light. Too little sun sends the plant into big leaves instead of roots.

10Bok Choy
Compact dwarf types suit a 5-gallon pot and a balcony that sees sun for only part of the day. Keep the mix evenly moist, because a pot that dries out is a common trigger for early flowering. If your spring swings between cold and warm, buy a variety sold as bolt resistant.

Start with the pot, not the plant. Buy the biggest containers your balcony and your back can manage, fill them with fresh potting mix, and make sure every one drains. Check your building's rules on weight and dripping water too. Then pick two crops from this list, one quick and one slow, and learn what your balcony likes before you add more.

Questions about this list
How much sun does a balcony need for vegetables?
Fruiting crops like tomatoes, peppers and eggplant want 6 or more hours of direct sun. Leafy crops such as lettuce, chard and kale can get by on about 4 to 5. Count the hours on a clear day before you buy plants.
Can I use garden soil in balcony pots?
It is better not to. Garden soil packs down in a pot and drains poorly. A bagged potting mix stays loose and keeps air around the roots.
How often should I water balcony vegetables?
Check the mix with a finger every day in summer. If the top inch is dry, water until it runs out the bottom. Small pots and windy spots dry out fastest.
