I think they would work fine, will need to put some drainage holes in the bottom. The downside I have found of plastic pots is after just a few seasons in the sun they start to crack.

Yes you can. I grow Figs in Containers and very successful. That is what I do:
1- The soul has to be special mix of soil, perlite, and Moss to make it airy and retain moisture.
2- To prevent crowding of the roots. I drill holes in the side of the container, not in the button and plant the container half way in the ground. By this way if I am using 16 Gallons container make me as if I am using 60 Gallons container.
3- In winter where it is freezing I dig the containers out and shelter them in the Garage. It is dual benefits A:you shelter your plants from freezing weather B: you trim the roots for the plant to make new ones next season, remember with the shovel I clip the roots outside the container.
This method is good for those who live in climate which gets freezing in winter and those who may be one day move and take their plants with them.
The reason I said don't put holes in the button and close any ones if existed is that if you allow the roots to travel from the button holes you will need Popeye muscles to pull that sucker out of the ground.
Good Luck

Save your back and go with nothing larger than 15 gallon. The berries do fine in even smaller pots. See my recent post below.

I have 62 fruit trees in pots mostly 15 gallon or smaller. No more 30 gallon pots for me. Some of my best fruit comes from potted trees and berries.

foolishpleasure- what's a button hole?

I bought those to start with not knowing much about containers. I wouldn't buy them again. Biggest thing is they crack very easily after a year. The cold weather makes it even worse. It may have to do with no UV protection. Nursery pots have UV protection.

If anything go with big wood pots and put them on wheels. If not you may have to splurge and order some 15 gallon nursery pots or bigger like I did just yesterday!

I'm tossing these things (I have 2) in the garbage after this season.
