What to do with these Medlar (Mespilus germanica) cuttings?

I just got about a dozen medlar cuttings in the mail yesterday, all my research says that grafting to medlar, pear or quince rootstock is the preferred method, however the cuttings are already breaking bud and my rootstock is weeks or maybe a month away from being ready for grafting (its in the ground, covered in 18" of snow). So i'm thinking of trying to root them indoors in 50/50 perlite/vermiculite with #8 rooting powder and humidity domes. Other options including rootings outdoors (freezing every night), rooting in unheated hoophouse (frost most nights) or rooting in a root cellar (no frost/ no light/ cool and humid).

Any thoughts on what is most likely to get decent results?

I am DEFINITELY NOT an expert....And as such, I would try all the things you suggested and hope some / all work!! Either way, good luck, and maybe someone smart will answer this.....

Hawthorn is another good option for grafting. That's what people use around here. If it grows wild where you live, I'd try it.

i just planted my first 5' tall medlar tree last year from a mail order co..and it had it's first fruit its first year..i was so surprised. I let the fruit "rot" on the tree cause i wanted it for the seeds to try to plant more this year (not sure how they'll do)..will see I guess

Hey Maine Aaron, did you have success rooting the medlar cuttings? I have some extra scionwood im thinking of rooting.
I grafted so many successfully, but would be interesting to see if they can root as well. If they are anything like rooting quince, I expect it would be very difficult... So curious of your results.

I tried grafting the first time this feb and it was Medlar on Hawthorne, worked like a charm leaves zooming all over
