Herbs were rotting on my balcony until I stole an idea from my coffee routine
I noticed my basil and mint were always waterlogged, even with drainage holes. Turns out, placing pots directly on concrete prevents proper runoff. I started using old wine corks under each pot to lift them slightly. Now, water escapes freely, and my plants are thriving.

Honestly, the wine cork trick doesn't sit right with me. They're too soft and can compress or rot, defeating the purpose of lifting the pots. I've had much better luck with those little plastic pot risers you can get at any garden center. They're cheap, designed for this, and won't decompose like organic materials. Plus, they keep the air flowing evenly under the pot, which corks might block. Have you tried anything more durable, or were corks just what you had on hand?

Something that hasn't been mentioned is how the balcony material itself can play a role (like, if it's sealed concrete versus porous stone). @sean_lane98's point about rocks trapping moisture made me realize that even with lifters, if the surface doesn't breathe, you're just moving the problem. I've used leftover ceramic tile spacers (the little crosses from DIY projects) because they're rigid, allow gaps, and won't decay. They're often free if you have them lying around, and they handle weight without compressing. Plus, they keep the pot level, which corks sometimes fail at if they're uneven.

Switched to plastic risers after my corks got moldy, and @diana_knight is right about the airflow. I mean, the corks worked for a season but started to decompose in the dampness, which attracted bugs. Now I use those little green plastic feet, and they keep the pots elevated without any blocking, plus they're easy to clean. Idk, maybe it's just me, but seeing the water actually drain away makes a huge difference for root health.

Hold on, I've been using corks for ages without any mold problems. I just give them a quick soak in diluted bleach, let them dry, and they're good to go. They don't compress if you use enough of them, and the airflow is fine because they're round. Those plastic risers always end up warping in the heat for me, and then the pots wobble. I guess if you maintain the corks properly, they last just as long. Plus, it feels better to reuse something that would otherwise be trash.

Seriously, you're relying on bleach soaks to keep organic material from breaking down? That's a temporary fix at best. I've seen corks completely disintegrate under heavier ceramic pots after one rainy season, leaving permanent rings on decking. The round shape actually minimizes contact points so much that larger pots become unstable, especially in wind. And claiming they don't compress is wild when you're using them under anything with real weight, like a planter full of wet soil.
