I have occasional grafts/buds that seem to flood out - on various species -
mulberry, pecan, hickory, walnut, persimmon. Haven't yet figured out
what's going on - other grafts/buds done the same day will do just fine.
I'm planning to get out and bud a few mulberries in the next few days,
using several different techniques, just to see if any seem to work better
than others.
Wonder if an inverted T-bud placement would be less likely to flood out?
Might even try that 'sap-stopper' technique, a modified bark graft, where
instead of completely beheading the rootstock, you just cut 3/4 to 7/8 of
the way through the stock, break it over, then do a simple bark graft. The
still-connected portion of the rootstock acts as a 'sap-drawer' or 'relief
valve'. I've had better success with this technique on walnuts than with
anything else I've tried.
I've done simple whips, whip & tongue, T-bud, bark grafts, cleft grafts on
mulberries, all with reasonable success rates, but I from the small numbers
I've done, cleft grafts have seemed to have the greatest success rate. All
these, with the exception of T-budding, were done with dormant-collected
scions and actively growing rootstocks.
