If you have good soil to begin with, and add some animal manure composts and other amendments to it, it will do fine. I'm using a few pots for the first time this year. I have always been an in the ground guy, and will have a few patches like that this year too. Like everything in life, each has it's pros and cons.
Many who grow in pots have poor, rocky, too wet or too dry soil. Pots do help to keep other plants from sending their roots to steal your ferts and water. But above ground especially, they are not good at water retention. Above ground pots are higher, so they would catch more sun when they are young, so maybe grow a little faster.
Planting in the ground will be better for water retention and stealth. But you can run into all sorts of plant killing varmints. I lost a few plants last year to termites. Folks further up north have to deal with gophers. Slugs can get you no matter where you grow.
When digging holes, wider is more important than deeper. Last year I did one kiddie pool sized hole. I put the plant into it when it was still real young, and it turned out to be a male, {this was Big & Stinky, one of my best studs last year}, but when I chopped him, he was 10 feet tall and 8 feet wide. The wider the root ball, the bigger the plant will be.
