Starting back around 2007, I started to grow a few containerized, fig trees. Fig trees do very well in large 15-25 gallon containers, and they can be moved into a cool, garage for overwintering. I use to keep my fig trees in an unheated garden shed. Not a great choice, but it was the only place I could store them for the long winter. I live in Zone-7b NYC. A miserable climate for growing Mediterranean fig trees. I managed to keep them alive and well for 5-6 years, and they ripened delectable figs each summer.
But, all good things must come to an end. The trees lasted until the terrible winter of 2012-2013. The freezing temperatures and long cold winter killed all my trees. I had a tree, my pride and joy, that had a trunk on it that was as fat and thick as my upper arm...and put out golden-yellow figs that were as sweet as sugar. It froze to death.
Fig trees that are grown in big containers have to be watered, consistently. Go on vacation, or forget to water on a hot day, and trees will be stressed, and more than likely, drop fruit. Not good. It's a commitment and the constant care and watering can become a chore. Fig trees are like having a "botanical dog" that requires attention, feeding, watering, etc. Screw up, and the tree dies.... or worse, doesn't bear fruit.
But, if you are retired, like to stick around the yard, like to cultivate trees, plants, veggies, fruits, etc....don't hesitate to grow a nice fig tree, either planted in ground or containerized. Do some homework and figure out what you'll need to do to keep the tree(s) alive over the winter. Winters will be your biggest problems if you live where temps drop below 40* F. Fig tree roots will die if they are frozen in icy soil.... or if roots freeze solid growing in a container. The results are the same.
You can't go wrong with growing "Black Mission", "Hardy Chicago" and/or the slightly inferior "Brown Turkey" which can split, get insipid and washed out if it gets too much water at the roots as figs ripen. If you decide to grow in containers ....then, you'll get to decide when figs get watered.
Pick your poison.
