Will my hosta die if I split when they are foot tall?

I found an article on how and when to split Hostas... http://www.nhhostas.com/dividing-hostas/, good luck

Thank you for the info. I see you are from Fort Collins. I was there in April. Nice vacation

Just cut straight down through it. No problem.

Hostas never die!

No they never die and keep coming back year after year i dug mine up 1 year and got rid of them and guess what they came back go figure

No, but try to divide in early spring or late fall.

They will look raggedy at first but always rebound and flourish

No way!!! I've split so many and they come back the next year bigger and heartier.

Not at all.

Thank you John.

Thank you everyone for all your help.
