Stem Splitting

[Blake Anderson]

I am growing wasabi and the petioles are very similar to rhubarb stems.
I have splitting up the center lenghtwise of the stems on some of my plants.
Does anyone know what could be causing this type of condition?

Sorry Blake, I have no idea as I have never grown Wasabi. I did watch a programme about it a while ago though.

Whereabouts are you?
