David,
I don't have refrigerated storage for rootstocks, so my experience might be
relevant. The rootstocks are shipped to me dormant, but at least in recent
years three to five days in warm transit often will start them into growth.
So I graft dormant onto growing (usually still somewhat behind where the ones
in the field are). I may take a while to finish what I start, so some of
the rootstocks are pretty well along. I don't think that heeling them in
would be a good idea, since they put energy into growing roots that will
then get broken off when you dig them for the workshop. They seem to be
able to tolerate hanging out together in the bag they are shipped in. They
will still grow new roots, but you'll break fewer of them than if they have
gone through planting and unplanting. I keep them as cool as I can (weather
dependent). The first year I grafted I tried callousing them as most
directions say that you should, but since then I've planted them right out as
soon after grafting as I can and they do fine. They often will be going out
when the other trees are well along; no problem.
In sum: as long as the scionwood is dormant, the grafts have a good chance
of taking. They can be planted out immediately after grafting. I suspect
that it's a bad idea to heel them in.

< Do any of you experienced orchardists have any advice
to offer on the wisdom of grafting onto dormant rootstocks, to be planted in
the ground
immediately afterwards, at a time when most trees have long since broken
dormancy, and
indeed may well be in flower? What think you of the idea of actually heeling
in the rootstocks
when, (and presumably if), I get them ahead of the workshop, and allowing
them to break
dormancy prior to the workshop? (ie now, instead of grafting dormant scions
on dormant
rootstocks - which ultimately is not really different fom winter grafting - I
will be grafting onto
actively growing rootstocks, (more akin to field grafting, except that the
poor rootstocks are
going to be rudely ripped from their beds and replanted elsewhere, at a time
they are
desperately trying to heal catastophic (at least from the perspective of an
apple tree)
wounds.)>
