My experience is that the question of nurse limbs relates more to size that to species. On larger caliper rootstock (anything over an inch maybe) a nurse limb is a must. Just too much shock to the root otherwise. On smaller stuff, the nurse limb is generally not necessary (in my experience....) I do a lot of "field grating" persimmons. Smaller stuff always does fine without a nurse limb. I have never noticed that nurse limbs do much harm either. The "sapping away energy" has not been a problem in my experience. On transplanted rootstock, I will sometimes leave live material from the rootstock on there, to help support the root, for the first summer at least (on a spring graft). You HAVE to take that away next year, and stay on top of it thereafter.

I have had good experiences using nurse limbs when grafting to apple and
pear root sprouts. However, now I am grafting to native persimmon
rootsprouts and wonder if nurse limbs will be counterproductive by
drawing too much energy and nutrients away from my graft.

Does any one have experience using this technique and would consider it
beneficial when grafting to persimmon, pawpaw or hickory?

Hello Betsy,

I never use nurse limbs for the very reason that you stated above, I cut
everything off below the graft. And on all species.

There was a member of the Indiana Nut and Fruit Growers whose name was
Jim Wood who had many nut trees, especially pecan. Because of the
problem of bleeding when grafting nut trees he developed what he called
the " Sap Stopper Graft. " He did a lot of grafting on pecan trees 6
inches in diameter and more. What he did was cut about half way through
a six-inch tree for example then push the top over on the ground so that
was still attached. This seemed to divert the sap from the cut area
which he then grafted. Then after the graft was well-established and
growing he would finish cutting off the half that was now laying on the
ground. I've seen some of his work and it seemed like is a viable method.

Jerry
