The link below has some info for your plant.

For a 4' tall plant a 5gal sized pot should be fine but bigger is better.

Since you've grown other things, the learning curve won't be too steep.

My rec would be a clean pot, new potting mix, don't over water or over fertilize and have gobs of fun :-)

thanks so much! :D im so excited!

A half whiskey barrel sized pot would be better if you have room.

Drill holes in the bottom for drainage!!!!!!!!! And all over the sides to get air to the soil, and DON'T OVERWATER! :)
Fertilize with something like fish emulsion or seaweed extract, it is really difficult to overfertilize with them.

No questions are ridiculous. I would though build a homemade earthbox. The plans can be found online and use just a basic discount store plastic container or 2 if you splurge.

That way your baby will have allot of room to play in and produce fruit.
Be careful on your balcony for scorching sun and wind.

You probably should fertilize and fish emulsion is very good early, but is best to stop and use a manure tea or if you have to resort to chemicals once fruits start as sometimes they can make a fishy taste to the fruit if too concentrated.

Please be aware that containers are wet dirt and heavy. So once you start where you want it there is not going to be moving it around easy.

PS for watering a tray or larger lid helps as dripping on the neighbors will probably get their attention.

Hope that helps.

You could also grow it as an "upside down" plant. One source for this would be Gardener's Supply Company (www.gardeners.com). They even have a stand you could get to hold it, if you can't put up a bracket on your outside wall. One plus of doing it this way is that these are "self-watering" so you don't have to worry about over or under watering it! Another plus is that it should take up less space on your balcony. Just a thought. I've used their self watering boxes in the past, and they were terrific! This year, I'm doing two of the "upside down" tomato plants. MacThayer
