That is exactly what you do
One can do it while the plant is in the ground or in a container.
There are Youtube videos also to help you understand and develop technique.
There are different techniques to use and learn and there are some risks involved.
I will use it for late season tomatoes(the green ones) to hasten the ripening on the vine and on ferns and hostas, bananas at transplant or up pot.
Root-prune - Definition and More from the Free Merriam-Webster Dictionary.
In Snarkies(Basjoo) case root pruning should cause a few more pups to develop and maybe a little more height/vigorous growth in what is left of his grow season.
However with a Basjoo the older they are the larger they get, as the corm size increases with age so will the height of the plant in subsequent years.
