A Landlord-Friendly Balcony Garden

I assumed a balcony garden meant drilling planter boxes into the railing, which meant asking my landlord, which meant it wasn't happening. Then I actually read my lease and built the whole thing for under $40 without touching a single screw.
What You Actually Need
Three freestanding pots (roughly $6-8 each). No hardware, no permission, and they move with you at your next lease. A 12-inch pot is the sweet spot for most balcony space without crowding a walkway.
Potting soil, one bag (around $8-10). Covers all three pots with some left over.
Seeds or starter plants (around $10-12 total). Herbs are the most forgiving starting point — basil, mint, and rosemary all tolerate inconsistent watering and give you an actual reason to check the balcony daily.
A cheap plastic watering can (around $5). Anything works; you don't need the aesthetic version.
Total: comfortably under $40, and every item leaves with you.
Building It — The Actual Steps
Fill each pot with soil, leaving about an inch from the rim
Plant one herb type per pot, spaced per the seed packet or starter tag
Place pots where they get the most consistent light your balcony offers — usually along the railing, not tucked in a corner
Water immediately after planting, then check daily for the first week while roots establish
What's Actually Off-Limits
Standard leases restrict permanent alterations — drilling into railings, walls, or the balcony floor, and anything affecting a building's exterior appearance. Freestanding pots don't touch any of that. If you're unsure, a two-line email to your property manager clears it up before you spend anything.
Zero Trace at Move-Out
Because nothing is attached to the building, moving out means picking up three pots and walking away — no patching, no restoration, no deposit risk.
The Quick Version:
Three freestanding pots, soil, herbs, and a watering can — under $40 total
Herbs are the most forgiving starting point for a first balcony garden
Nothing gets drilled or attached — fully move-friendly
Check your lease's exterior appearance clause if you're unsure, not the "no alterations" clause — freestanding pots aren't alterations
If indoor plants are more your speed, plants, light, and a calmer apartment routine covers the same idea for indoor, low-light spaces. The Resources page has the exact pots and starter herbs I used.
