Balcony Herb Garden: What to Grow and How to Keep It Alive
Herbs are the perfect balcony crop: shallow-rooted, compact, quick to harvest and happy in the small pots a balcony can actually hold.
Quick answer
Grow basil, chives, thyme and oregano on a sunny balcony, and mint, parsley, and cilantro on a shadier one. Use railing planters plus 1-2 gallon pots with drainage, water when the top inch is dry, and harvest weekly so plants stay bushy instead of leggy.
Choose herbs by your balcony's light
| Light | Grow |
|---|---|
| 6+ hours sun | Basil, rosemary, thyme, oregano, sage |
| 4-6 hours | Chives, parsley, cilantro, tarragon |
| 2-4 hours | Mint, parsley, chervil, lemon balm |
A layout that fits a tiny balcony
- Railing planter: chives, thyme and oregano (shallow roots, full sun)
- Floor pots against the wall: basil and parsley in 2-gallon pots
- One hanging pot: mint or trailing thyme
- A small shelf or stool to add a second level of pots
Care routine that takes five minutes a week
- Check soil daily in summer; water deeply until it drains
- Feed a half-strength liquid fertilizer every two weeks
- Pinch tops and remove flower buds weekly
- Rotate pots so all sides get light
Helpful tips
- Buy supermarket basil, split the crowded root ball into three, and pot each piece — you get three plants for the price of one.
- Keep herbs within arm's reach of the door or you will stop using them.
- Bring chives and mint indoors in late autumn for a few extra weeks of harvest.
Common mistakes to avoid
- Growing herbs in tiny 4-inch decorative pots that dry out in hours.
- Letting basil flower, which turns leaves bitter and slows growth.
- Overwatering woody Mediterranean herbs.
Frequently asked questions
Can I grow herbs on a shaded balcony?
Yes. Mint, parsley, chervil, and lemon balm all produce well with two to four hours of sun or bright indirect light.
How deep should a herb planter be?
Six inches is enough for chives, thyme, and oregano. Basil, parsley, and mint do better in eight to ten inches.
In short
Match herbs to your light, use the railing for the sun-lovers, and harvest often. A balcony herb garden pays for itself in a month.
