Raintree sells Krymsk 5 (which is what I have been using).

Or did you mean to say Gisela 5? That's what I just got from Raintree. I couldn't find another source of Gisela 5 on the internet anywhere, and I looked pretty hard. Raintree's got it.... but be warned, you're going to have to pay good money to get it.

No, I meant Krymsk 5. I wasn't aware they had Gisela. Must be new. When i look at the online catalog for cherry rootstock all I see is Krymsk 5. They sell lots of trees ON Gisela 5. Perhaps that's what you meant.

Yep, that's what I meant.

I got krymsk 5 from cummins nursery this year.
