Two years ago I couldn’t keep a basil plant alive for three weeks. Figured I just didn’t have a green thumb and left it at that. What actually happened: I bought the thing on a whim because I was sick of throwing out wilted grocery store herbs, stuck it on the balcony, watered it whenever I remembered. It was dead inside a month.
Now I’ve got tomatoes, peppers, herbs, a couple of flowers going on that same balcony. No training, never read a gardening book. Here’s roughly what happened, mistakes included.
Round two
A friend talked me into trying again. This time I went big instead of starting small — tomatoes, peppers, cucumbers, a couple of flowering plants, more herbs, all bought the same week and crammed onto a balcony that isn’t actually that big. Within a month most of it was struggling or dead. I had no idea what any one plant wanted, so I watered everything on the same schedule and hoped.
Cucumbers died first. Then a tomato plant. Then some flowering thing I don’t even remember the name of. Once I gave up and pulled back to just basil, mint, and a couple of green onions regrown from kitchen scraps in a glass of water, I actually saw growth instead of slow decline. That’s the only reason I didn’t quit for good right there.
The tomatoes that wouldn’t grow
Once the easy stuff was fine, I tried tomatoes again, more carefully. Still grew slower than I expected, stayed smaller than what I saw online. Blamed the water, blamed the soil, blamed bad luck. Took embarrassingly long to consider the balcony itself wasn’t sunny enough.
I’d assumed it got “a lot of sun” because it felt bright out there. So one week I went out every hour or so and wrote down direct sun or bright shade. Four to five hours in the afternoon, roughly — I never actually measured it properly. Most vegetables want six-plus. That explained the stunted tomatoes immediately, and also why the mint and basil had been fine the whole time without me doing anything.
Overwatering, for months
Around the same time, two pepper plants started yellowing at the tips. My first instinct was more water — felt like the safe default. Made it worse. Didn’t connect the dots for a while because I genuinely believed you couldn’t overdo water.
What fixed it: sticking a finger in the soil before watering instead of watering on autopilot. Dry an inch down, water. Still damp, leave it. Yellowing cleared up in a couple of weeks. The soil never got a chance to dry between waterings, so the roots were basically sitting there suffocating.
Soil itself was part of it too. I’d been using dirt dug up from a patch near the building, figuring dirt is dirt, and it compacted into something close to clay after a few waterings. Switched to actual potting mix, made sure every pot had real drainage instead of one small hole. Obvious difference, almost immediately.
Pot size matters more than I expected. Small 6–8 inch pots for herbs, lettuce, green onions — they dry out fast, need watering more. Peppers and smaller tomato varieties want something like 10–14 inches, big enough for the roots without taking over the balcony. Full-size tomatoes and cucumbers need a proper large container or grow bag, something to stake them up as they get taller, and pretty consistent watering once established.
Then a few things went wrong at once
Once watering and soil were sorted I got overconfident and packed plants too close to fit more in. Airflow got blocked and I started seeing fungal spotting on a few leaves. Around the same stretch I noticed aphids on one plant and figured I’d deal with it later — that turned into an infestation on two neighboring pots inside two weeks, because I wasn’t checking closely enough.
I also fertilized more often than I should have, trying to speed things up, and burned the roots on two pepper plants. And there was a tomato seedling I panicked over and pulled out entirely because the leaves drooped slightly after transplanting — normal transplant shock, in hindsight, and it probably would’ve bounced back on its own in a few days.
The overwatering habit had probably left everything weaker to begin with, which is likely part of why the fungal spotting caught on so easily. The aphids crept up because I was still mostly watching water levels and hadn’t yet trained myself to check leaves and undersides properly.
Cucumbers, again, still nothing
Tried cucumbers again the following season doing everything I thought I’d learned — better soil, careful watering, more spacing. Barely produced anything. Took two full seasons before I accepted the balcony just doesn’t get enough consistent sun for cucumbers, full stop, no matter what else I fix. Gave that spot to more lettuce and herbs and stopped forcing it.
Somewhere in that second season I started mixing compost into the pots every few weeks, since container soil apparently gets depleted as plants pull nutrients out. Plants looked better by month two or three. Couldn’t tell you how much was the compost versus everything else I’d already fixed by then.
Where it’s at now
Hasn’t saved me real money. Still bad at anything that wants full uninterrupted sun. But there’s a routine to it I didn’t expect to like this much, and having fresh herbs on hand whenever I need them has made every dead plant along the way worth it.
If you’re starting out, don’t do what I did the second time. One pot, one easy plant, somewhere you’ll actually check on it — that beats crowding a balcony with everything at once.
Still don’t know what that flowering plant from round two actually was. Never identified it, tossed the tag before I thought to look it up. Everything else I lost that year traces back to a specific fix — too little sun, too much water, whatever. That one’s just gone.
