Can you successfully/safely cut back and shorten the tubers?

I have watched 2 youtube videos today about starting dahlias, and both guys were experts or pros, and both had started their tubers in small market pots(square) about 4-5" diameter at the top.

That means the pots are even narrower a few inches down where the tubers would be placed. Their plants are coming up right in the centers of the pots too(?)

Most of my tubers are too long to place into a pot that small, and the ones that are small enough would have to placed in such that the stems wouldnt come up in the center of the pots, they would come up towards the sides of the top of the pot, because obviously the stems grow from the end of the tubers, not the middle, so I dont know how they are getting them to grow in the middle.

They both said they came from tubers too. So either they have tiny tubers, or they are cutting the back ends shorter.

Is that likely what they would do? How much can you remove from the backs of the tubers without killing them?

RE: Can you successfully/safely cut back and shorten the tubers?

I cut off close to a third of some of mine last year and they did just fine. It was my first time cutting them down, so I was nervous about it. I wouldnt worry about centering them in the pot, you are going to be taking them out of it anyway to plant them.

I just nestled them into the soil for the first few days after cutting them , and then buried them deeper after the ends had a chance to dry out a bit.
