My purple fountain grass is in a container and getting bigger than I thought it would. Is there a way to trim without a severe pruning?

Fountain Grass can reach heights up to 4 feet and just as wide.
Cutting the grass back to soon could cause water to puddle down into the crown and cause root rot.
I would recommend maybe relocating the pot to a location that the size is less problematic.
Perhaps you could give the plant to someone with the space to grow it.
Here are a few links.
