This made me sit up and take notice. I grafted mulberries this spring for
the first time, and got good results at first, with takes on 8 grafts. Then
hail knocked off a couple of buds but the grafts still held, and then they
all proceeded to die off, some within weeeks, others taking a couple of
months. I think they are all dead now. And no, my local stocks are not
paper mulberry. Anybody have experience with mulberries?
Actually, my initial failure sounds like Melanie's problem. Most of my
grafts went on small twigs or branches about 1/2" diameter, but the largest
tree was about 2" in diameter. It wept a lot of white sap all over the
stump, and the two grafts on that one never showed any signs of life. Donna

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.
