How large are the pots? As stated by isgen they would be competing and may have different watering needs, also you would have to keep an eye on your plants and may have to prune them to force them to share space, and feed them on a regular basis. Impossible? No, ideal? Not really, but I have grow. Two peppers in a 3 gallon pot before they were not as productive or large in size when compared to their counterparts in pots by themselves.

Thx for the replies -- this one pot specifically is 20 L or around 5,3 gallons. I know that the peppers will not be as productive competing with other plants, but as of now, it is not the top-top priority for me to get huuge peppers. It is more the idea of having variety in the garden that I am going for :)

Isgen -- good idea with the board across, and putting the other plants in pots on top of that. Maybe even just put the pots on top of the soil of the big container ? I still think though, that a more than 5 gallon container should be able to host more than a single pepper ? (and my fairly small balcony in mind, getting a huge bushy pepper could also become a problem)...

C. Chinese varieties usually get bushy/tree like. Here is a favorite pic of mine and its in a small pot. If you decide to plant in the same pot keep us updated because I am interested in how they do.

wauw habjolokia - thats pretty big for a small-ish container. Mine are mostly c. annuum, read somewhere that they do better in colder climates - being in scandinavia that made sense to me :) Also on a balcony they wont get full sun all day, so a doubt they will thrive as good as yours... but I'll keep you posted on the progres :)

That plant actually got 6-7 hours of morning to early afternoon sun and was shaded by the town house the rest of the day. I think if you have 6-8 hours you should be fine. Look forward to your updates and progress.

Rosemary needs its own container due to the fact that it is an arid climate plant. They are easy to overwater. Lavender is tbe same way. Treat oregano like mint, it takes over containers quickly,

Chili is the nasty gemish Tejanos make with beans. Chile is the fruit.

I had this going happily last year in a sunny courtyard for several months. The container is fairly deep. I used a rich potting mix and my garden compost. The chives worked well for insect control. In future I would not add the mint as it spread too fast. The hot pepper (or chilli as we call them in England and the rest of the Commonwealth) was a Habanero. I suspect it was a Hab de Arbol...never got to see the fruit.

It is past tense because my German Shepherd decided she didn't like the set up. She carefully removed only the Hab when we weren't around.
