I'm not sure what this is but the stalk right at the base looks weird what is this?

Is it firm and alive feeling? Your soil might just be a bit compacted, exposing the crown a bit.
If it's soft and squishy or slimy then you have some rotting.

if its rotting then what do I do to stop it? I guess I should just lower the water level when it floods?
