Apple rootstock question

I have some BUD 118 that I’ll be grafting in the next few days, however my nursery beds aren’t ready (received a late freeze/snow). Can I trim the bottoms of rootstock to fit better into a pot for temporary planting, or is risky with the roots bring too delicate? Thank you!

Since the root and leaves amounts are balanced, you need very little root to push out one scion upon grafting.  They can be trimmed a lot.

Great, thank you. It will just be temporary in the pots (hopefully 3 weeks max) so this is good news
